Introduction

Families with autistic adolescents navigate distinct relationship dynamics, influenced by factors including access to appropriate supports, societal attitudes toward autism, and neurodevelopmental differences in attention and cognitive processing. Research demonstrates that autistic individuals typically exhibit a monotropic attention style—channelling attention intensely toward fewer interests at any given time—in contrast to the polytropic tendency to distribute attention more broadly across multiple stimuli simultaneously ([70], Murray et al., 84). This fundamental difference in attentional processing, supported by neurobiological evidence of minicolumnar organization differences in the prefrontal cortex [21], underpins many aspects of autistic experience including sensory sensitivities, communication patterns, and what is often termed the “double empathy problem” [80]—the proposition that communication breakdowns between autistic and non-autistic people are bidirectional, arising from mutual differences in experiential understanding rather than from deficits located solely within the autistic individual. Understanding monotropism is essential for practitioners working with families, as it reframes apparent “deficits” as differences in how attention is allocated and sustained [33, 39].

The monotropic cognitive style characteristic of autism shapes family dynamics in specific ways. When attention is intensely focused on a current interest or activity, transitions to new activities or conversations may be experienced as jarring disruptions rather than natural shifts (Murray et al., 84). Family members may misinterpret this as rigidity or disinterest, when it reflects the cognitive reality of single-channelled attention processing. Understanding this allows families to develop strategies that work with, rather than against, monotropic processing—such as providing advance notice of transitions, using interests as bridges to connection, and recognizing that attention to one domain necessarily means reduced attention to others.

Research over the past two decades has increasingly documented the experiences of caregivers and impacts on family well-being, including shifting expectations, social isolation, and complexities of supporting co-occurring mental health needs [1, 30, 75]. Families often navigate fragmented healthcare systems, social stigma, and limited public understanding of autism, particularly in educational settings [95]. These systemic and social barriers deepen caregiving demands and expose persistent gaps in available services.

While quantitative studies have generated important insights into family stress, mental health patterns, and relationship dynamics [33, 35, 74, 96, 101], less is known about how these dynamics are understood and experienced by families themselves, particularly from the perspectives of autistic adolescents. Qualitative research has begun addressing this gap by exploring lived experiences [110,111,112,113], yet integrative frameworks that translate empirical findings into practice guidance remain scarce.

The Need for Family-Centred Practice Models

Existing interventions for families of autistic individuals have shown varying effectiveness. Cognitive-behavioral interventions (CBIs) have been linked to reductions in parental stress, anxiety, and depressive symptoms, as well as improvements in parent–child relationships [71]. However, these interventions may not fully address broader family-level priorities such as fostering open communication, improving cohesion, or building resilience [105]. Family systems therapy appears promising for strengthening these aspects, with systematic reviews documenting evidence for systemic interventions across a range of child-focused difficulties [22], though autism-specific family therapy research remains limited [58, 105].

Most studies on family interventions have focused on caregivers of autistic children aged 2—12 years, reflecting a broader emphasis on early to middle childhood support [39, 77]. McCrossin and Lach’s [77] scoping review further demonstrates that parenting programs for children with neurodisabilities typically focus on child and parent outcomes without consistently examining the family unit, with general family functioning representing only 31.6% of family-level outcomes measured across 29 studies. In contrast, relatively few studies have examined interventions tailored to autistic adolescents (13—19 years) and their families, despite the distinct developmental transitions and emotional shifts that characterize this stage. A recent systematic review suggests that psychological supports such as mindfulness-based interventions (MBIs) and cognitive-behavioral therapy (CBT) may benefit both autistic adolescents and their parents [71], though additional high-quality randomized controlled trials are needed to clarify how these interventions influence family dynamics more broadly [39, 62].

Notably, most family research has centered on parental perspectives, with limited inclusion of autistic adolescents’ own voices and experiences. This is particularly concerning given that adolescence represents a critical developmental period when identity, autonomy, and family relationships undergo significant transitions. Research indicates that during adolescence, brain development proceeds unevenly; for autistic individuals, these developmental patterns interact with existing neurological differences [92]. The divergence between monotropic (autistic) and polytropic (non-autistic) cognitive processing styles may create particular challenges during adolescence, when hormonal changes and identity development intensify relational dynamics within families. Additionally, a predominant focus on measuring perceived negative outcomes such as stress or conflict has contributed to a gap in understanding the strengths, adaptations, and positive transformations that can emerge in family life [66].

Positioning Against Existing Family-Focused Interventions

Several evidence-based interventions exist for families of autistic children, yet few adequately address whole-family relational dynamics from a neurodiversity-affirming perspective. McCrossin, Lach, and McGrath’s [78] content analysis of 22 randomised controlled trials of parent training programs for children with neurodisabilities found that theoretical frameworks were primarily focused on the individual child or parent, with little acknowledgement of the complex, relational, systemic context in which families operate—reinforcing the need for models grounded in family systems theory. Parent training programs such as RUBI [6] and Stepping Stones Triple P [121] employ applied behaviour analysis or social learning principles to equip parents with strategies for managing challenging behaviour. While effective for their stated aims, these interventions focus narrowly on the parent–child dyad, position behaviour reduction as the primary outcome, and locate the need for change predominantly within the autistic child. Similarly, naturalistic developmental behavioural interventions such as Project ImPACT [59] target social communication skill acquisition in young children through parent coaching but do not address broader family relationship quality. Social skills programs like PEERS [68] focus on individual skill acquisition for adolescents rather than family relational dynamics.

Co-parenting interventions such as Autism Parent Navigators (APN) represent important progress by addressing the couple subsystem, recognizing that parenting stress and autism-related demands affect partner relationships [57, 114]. However, these interventions typically focus on parenting coordination, stress reduction, and dyadic adjustment without extending to sibling relationships, whole-family identity reconstruction, or integration of neurodiversity-affirming frameworks that position autism as neurological difference rather than deficit.

More recently, Pennant [89] introduced Structural Family Therapy for ASD (SFT for ASD), which represents an important advance by addressing whole-family dynamics rather than isolated dyads. However, SFT for ASD emphasises restructuring family hierarchy and organisation rather than fostering mutual understanding across neurotypes, and does not explicitly integrate neurodiversity-affirming theory such as monotropism or the double empathy problem. What remains absent from the intervention landscape is a model that (a) addresses the family as an interconnected system across multiple subsystems including couple and sibling relationships, (b) centres relational connection rather than behaviour modification or structural reorganisation, (c) explicitly integrates autistic-led theoretical frameworks including monotropism, and (d) positions all family members—not solely the autistic individual—as participants in bidirectional adaptation. The present model addresses these gaps.

Purpose and Contribution

This article presents an evidence-informed practice model for enhancing family relationships and promoting connectedness in families of autistic adolescents. The model addresses recognized shortages of holistic family support interventions that meet individual family needs and work toward improving and strengthening relationships [39, 105]. Drawing on empirical research involving 44 participants from 18 families, including autistic adolescents, siblings, mothers, and father, the model integrates key findings to provide practitioners with theoretically grounded, evidence-informed strategies.

The practice model is situated within a biopsychosocial model [12], recognizing that social environments can disable or enable autistic individuals to participate fully [2, 50]. It emphasizes collaborative, person-centered approaches that position families as equal partners in planning, developing, and monitoring services [32]. The model comprises three interconnected components: (1) a conceptual framework explaining how autism impacts family relationships through disruptive and connective factors, (2) a six-element practice model targeting specific family domains; and (3) ten principles of practice guiding implementation.

This translational contribution bridges the gap between research and practice by providing actionable guidance for family practitioners, including social workers, family therapists, psychologists, and occupational therapists working with families of autistic adolescents.

Empirical Foundation and Methods

The seven findings informing this practice model derive from a phenomenological qualitative study involving 44 participants from 18 families in Canberra, Australia [109]. This study was approved by Australian Catholic University National Human Research Ethics Committee (HREC), study registration number 2019—33H. Participants were recruited via purposive sampling through autism organizations, schools, and community networks, comprising autistic adolescents aged 12—19 (n = 11), siblings (n = 9), mothers (n = 12), and fathers (n = 12). Five of the 18 families were multiplex families with more than one autistic member [100].

Data were collected through in-depth semi-structured interviews using open-ended questions and encouragers to facilitate rich narrative accounts. Interviews explored participants’ lived experiences of autism within family relationships and external responses to autism. A Family Advisory Group comprising autistic individuals and family members provided ongoing guidance throughout the study design, data collection, and interpretation phases.

Data analysis followed a constructivist grounded theory approach [24] and procedures involving immersion in transcripts, initial coding, development of basic themes, and synthesis into organizing and global themes. Analysis was conducted both within stakeholder groups and across whole family units. Methodological triangulation strengthened validity, comparing individual accounts with family-level patterns to identify convergent and divergent experiences.

Full methodological details are available in Trew [109].

Reflexivity Statement

The first author is an autistic autism researcher, bringing insider knowledge that facilitated rapport with autistic adolescent participants and nuanced interpretation of accounts. Ongoing reflexive journaling throughout data collection and dialogue with two supervisors (professors of Social Work) ensured critical examination of researcher assumptions and positioning throughout analysis.

Key Findings Informing the Practice Model

Seven key findings emerged from this research (see Table 1). These findings illuminate both challenges and strengths in family adaptation, highlighting the critical roles of coping strategies, communication patterns, identity negotiation, and external support in shaping family relationships. While the seven findings derive from the first author’s qualitative research program, they converge with patterns documented in independent autism family research internationally, including studies of parental coping [8, 67], bidirectional communication [29, 54], sibling caregiving [28, 108], service barriers [117], and family resilience [48, 118]. Notably, Gunty’s [48] systematic review of family resilience in families of children with ASD identifies stressors, resources, and meaning-making as the core elements through which these families navigate adversity—a tripartite structure that maps directly onto the disruption–connection continuum developed in the conceptual framework below. This convergence suggests the findings reflect genuine features of family experience rather than artefacts of a particular sample or analytic approach. The model thus represents a synthesis of one researcher’s deep engagement with families, validated against the wider empirical literature.

These seven findings converge to reveal two interacting patterns in family life: disruptive factors that create physical withdrawal and emotional distancing, and connective factors that foster togetherness, understanding, and security. Importantly, the findings also reveal that families are not passive recipients of these dynamics but active agents who develop coping strategies, construct shared identities, and build resilience through meaning-making [48, 118]. The conceptual framework and practice model presented in subsequent sections operationalise these findings to guide intervention.

A methodological consideration warrants acknowledgment: the empirical foundation for this practice model derives from a single qualitative research program conducted by the first author. While this allowed for deep, sustained engagement with families and theoretical consistency across findings, it also means the model has not yet been independently validated. The findings presented here should be understood as one researcher’s systematic interpretation of family experiences, requiring replication and extension by other research teams before the model can claim broader generalisability.

Conceptual Framework: Disruption and Connection in Family Relationships

The conceptual framework presented here extends the empirical findings reported in the original qualitative study [109] by introducing three contributions not present in that article: (a) the disruption–connection continuum as an organising mechanism that explains how multiple factors interact to shape family relationships; (b) explicit integration of neurodiversity-affirming theoretical frameworks including monotropism (Murray et al., 84) and the double empathy problem [80] as explanatory lenses, and (c) systematic mapping of the empirical findings onto established models of family functioning. In particular, the framework draws on the Circumplex Model of Marital and Family Systems [86], Walsh’s [118, 119] family resilience framework, and the McMaster Model of Family Functioning [37] to situate the empirical findings within the broader family systems literature.

The conceptual framework (Fig. 1) illustrates how multiple factors—including autism-related differences, support availability, and external responses—shape family relationships through two primary pathways: disruption leading to disconnection, and connection leading to bonding. This framework synthesises the seven empirical findings to explain the underlying social processes affecting family relationships.

The two-pathway structure resonates with established models of family functioning. In the Circumplex Model [86], family systems are understood along dimensions of cohesion (the emotional bonding members have toward one another) and flexibility (the capacity of the system to change its leadership, roles, and rules in response to situational or developmental stress). Balanced levels of both dimensions are associated with healthy functioning, while unbalanced extremes—disengaged or enmeshed cohesion, rigid or chaotic flexibility—tend to be problematic over time. The disruption–connection continuum in the present framework parallels this logic: disruptive factors push families toward unbalanced functioning (disengaged withdrawal or enmeshed over-involvement), while connective factors support families in maintaining balanced cohesion and adaptive flexibility. Communication, the third dimension of the Circumplex Model, operates as a “facilitating dimension” ([86], p. 148) that enables movement along the other two, a principle directly reflected in this framework’s emphasis on open communication as a connective factor.

Similarly, Walsh’s [118, 119] family resilience framework identifies three domains of key processes through which families navigate adversity: belief systems, organisational patterns, and communication/problem-solving. The connective factors identified in the present framework map onto these domains: ‘understanding and acceptance of each member’s differences’ corresponds to Walsh’s belief systems (making meaning of adversity, maintaining a positive outlook); ‘teamwork and united fronts’ and ‘family routines and predictability’ correspond to organisational patterns (flexibility, connectedness, mobilising resources); and ‘open and direct communication’ corresponds to Walsh’s communication processes (clarity, open emotional expression, collaborative problem-solving). Gunty’s [48] systematic review of family resilience in families of children with ASD reinforces this mapping, demonstrating that resilience in these families operates through the same core elements, balancing stressors and resources while engaging in meaning-making, that underpin the present framework’s disruption–connection continuum.

The McMaster Model of Family Functioning [37] provides complementary assessment constructs through its six dimensions: problem-solving, communication, roles, affective responsiveness, affective involvement, and behaviour control. Several of the empirical findings that inform this framework align with specific McMaster dimensions. Finding 3 (bidirectional failure to connect) and Finding 1 (behavioural impacts on relating) correspond to the McMaster communication and affective responsiveness dimensions respectively, while Finding 5 (sisters as co-carers) maps onto the roles dimension, where role allocation, accountability, and the distinction between instrumental and affective family functions are assessed. This alignment suggests that practitioners implementing the present model may find McMaster-derived assessment tools (such as the Family Assessment Device; [38]) useful for baseline and outcome measurement.

Disruptive Factors and the Path to Disconnection

Several disruptive factors have direct impacts on individual family members and bidirectional effects on interactions between family dyads. These factors push families toward what Olson [86] describes as unbalanced functioning—either disengaged (where members operate independently with limited emotional connection) or, paradoxically, enmeshed (where the intensity of caregiving demands produces excessive closeness that limits individual autonomy).

Stress and anxiety arise from navigating co-occurring mental health needs, sensory sensitivities, and behaviours that family members may initially find difficult to understand or anticipate. Aggressive behaviours may occur during periods of overwhelm, particularly when communication systems and environmental supports are inadequate (Finding 1). These experiences correspond to what the McMaster Model terms challenges in affective responsiveness—the capacity of family members to respond to a range of stimuli with the appropriate quality and quantity of feeling [37].

Anger and frustration emerge when family members misunderstand each other’s experiences or perspectives, and conflict results from divergent coping strategies, role confusion, or competing needs (Findings 2 and 3). In Circumplex Model terms, families experiencing these dynamics may oscillate between rigid patterns (where one member’s needs dominate and rules cannot be renegotiated) and chaotic patterns (where responses are impulsive and roles unclear) [86].

Bidirectional challenges in relating arise from differences in socio-emotional communication styles, reading emotions, and interpreting social cues—the ‘double empathy problem’ [80] experienced at the family level (Finding 3). These challenges are compounded by monotropic attention processing (Murray et al., 84), which may mean that autistic family members process conversation differently, requiring more time to shift attention between topics or interlocutors.

Caregiver duties and responsibilities create physical exhaustion, emotional fatigue, and limited time for relationship maintenance (Finding 2). When caregiving is distributed inequitably—as documented in Finding 5, where sisters assumed co-caring roles beyond developmentally appropriate expectations—this creates what the McMaster Model identifies as problematic role allocation, where necessary family functions are fulfilled at the expense of individual members’ wellbeing [37].

The presence of these disruptive factors facilitates physical withdrawal and emotional distancing between family members. Siblings may retreat to their rooms to avoid confrontations; autistic adolescents may withdraw into solitary interests; parents may become so focused on one child’s needs that relationships with other family members erode. This withdrawal and distancing result in impeded relationships characterised by limited communication, reduced shared activities, and diminished emotional intimacy.

When impeded relationships exist across multiple family dyads, the outcome is disrupted family connectedness—a pervasive sense of disconnection within the family unit. In Circumplex Model terms, these families present as disengaged systems where members “do their own thing, with limited attachment or commitment to their family” ([86], p. 147). This disconnection is particularly pronounced in families without regular respite, adequate professional support, or inclusive community environments (Finding 7).

Connective Factors and the Path to Bonding

Conversely, several connective factors positively impact individual family members and their interactions. These factors align with the key processes identified in Walsh’s [118] family resilience framework and with balanced functioning in the Circumplex Model [86].

Teamwork and united fronts, where family members coordinate efforts and support one another, correspond to Walsh’s [118] organisational patterns—specifically, the processes of connectedness, mutual support, and collaborative problem-solving that enable families to rally during times of stress. In Circumplex terms, effective teamwork reflects balanced flexibility: families that can reorganise roles and redistribute responsibilities without becoming either rigid (one person controls all decisions) or chaotic (no clear structure exists) [86].

Open and direct communication about emotions, needs, and behaviours is the facilitating dimension that enables movement along cohesion and flexibility [86]. It corresponds to Walsh’s [118] communication/problem-solving domain, which emphasises clarity, open emotional expression, mutual empathy, and collaborative decision-making. In the McMaster Model, effective communication is characterised by clear and direct messages where both the content and the intended recipient are unambiguous [37]. For families with autistic members, this requires attending to neurotype-specific communication preferences and processing differences, including monotropic attention allocation.

Family routines and predictability reduce anxiety and provide structure, aligning with Walsh’s [118] organisational patterns of stability through disruption and the Circumplex Model’s structured-to-flexible range of balanced flexibility [86]. Predictable routines are particularly important for autistic family members whose monotropic processing may make transitions between activities especially demanding (Murray et al., 84).

Spending positive time together through shared activities, family memories, and rituals builds emotional bonds that correspond to the Circumplex Model’s connected level of cohesion, moderate to high emotional bonding where family members feel close while maintaining some individual space [86].

Understanding and acceptance of each member’s differences, needs, and contributions maps onto Walsh’s [118] belief systems domain: making meaning of adversity, normalising and contextualising distress, and maintaining a positive outlook. For families of autistic adolescents, this specifically involves understanding autism through a neurodiversity-affirming lens rather than a deficit perspective, a form of meaning-making that Gunty [48] identifies as central to the family resilience process in this population.

The presence of these connective factors creates togetherness (shared experiences and coordinated efforts), greater understanding (mutual empathy and perspective-taking), and a sense of closeness and security (emotional warmth and support). These qualities result in bonded and strong relationships characterised by trust, reciprocity, and resilience [48, 118].

When bonded relationships exist across family dyads, the outcome is positive family connectedness, a pervasive sense of belonging, cohesion, and mutual support within the family unit. In Circumplex Model terms, these families function within the balanced range of cohesion (separated to connected), where members are “able to experience and balance” independence and togetherness ([86], p. 147). This connectedness extends beyond the family to include social and community connections.

The Role of External Factors

The framework recognises that societal exclusion and misunderstanding of autism reinforce family relationship patterns already characterised by interpersonal distancing and relationship disruption. External factors include stigma and discrimination in schools, workplaces, and community settings; limited access to autism-knowledgeable professionals and appropriate services; inadequate respite and support systems; and inaccessible or unwelcoming community environments (Finding 7).

These external factors operate through two mechanisms. First, they directly increase stress and caregiving demands on families, amplifying disruptive factors. Gunty [48] highlights that family resilience research has typically placed the responsibility for resilience on the family itself, without adequately accounting for contextual constraints on families’ abilities to be resilient, including socioeconomic status, minority stress, and systemic barriers to services. The present framework acknowledges that external factors can overwhelm families’ coping resources regardless of internal family strengths. Second, external factors shape how families perceive themselves and autism, influencing whether families adopt neurodiversity-affirming identities (which promote connection) or deficit-based views (which may exacerbate disconnection).

Social Identity Theory [106] helps explain this process. Families negotiate their collective identity in relation to autism and broader social categories. For some, particularly multiplex families where autism is common, embracing autism as a positive identity marker promotes group cohesion, psychological well-being, and social buffering against stigma [25]. These families actively push back against discrimination and create strengths-based family environments. For others, experiencing autism primarily through the lens of social exclusion and negative external responses reinforce disconnection and may lead to social withdrawal.

Dynamic Balance between Disruption and Connection

The conceptual framework illustrates that whether families experience greater connection or greater disconnection depends on the relative balance and interaction of disruptive and connective factors. This dynamic parallels Walsh’s [118] conceptualisation of family resilience as a process of balancing stressors, resources, and meaning making, not a fixed trait but an ongoing adaptive capacity. It also reflects the Circumplex Model’s hypothesis that balanced families have the resources and skills to shift their system in response to crisis, while unbalanced families tend to remain stuck in extreme patterns [86].

This is not a simple additive process; certain combinations of factors can swing the balance dramatically. For example, open communication (connective factor)—which must account for the autistic monotropic cognitive style, including the processing demands of simultaneously attending to content, facial expressions, tone, and turn-taking (Murray et al.,84)—may buffer against the impacts of challenging behaviours (disruptive factor), while lack of respite (external factor) may overwhelm families’ coping strategies. Walsh [118] frames such crises as potential catalysts for growth: a crisis can heighten attention to what matters, stimulating reappraisal, investment in relationships, and discovery of new strengths.

Importantly, the framework positions intervention as targeting this balance. Practitioners can work to: limit disruptive factors by providing appropriate supports, teaching coping strategies, and addressing external barriers; promote connective factors by facilitating communication, establishing routines, and building on family strengths; and enhance social buffering by supporting positive family identity formation and community inclusion. In Circumplex Model terms, the goal of intervention is to support families in moving toward balanced cohesion and flexibility—not to prescribe a single ‘ideal’ family structure, but to help families find their own functional balance between togetherness and separateness, between stability and adaptability [86].

The practice model presented in the following section operationalizes these intervention targets through six practice elements aligned with specific empirical findings.

The Practice Model

The practice model (Fig. 2) presents a situated family-based approach for practitioners working with families of autistic adolescents. It has dual aims: (1) enhancing family relationships, and (2) promoting connectedness among family members and within the family unit. The model comprises six broad elements, each addressing specific impacts identified in the empirical findings (see Table 1 for the mapping between findings and elements). These elements are guided by ten principles of practice (Fig. 3) that inform implementation across family domains.

The six elements were derived through a systematic process of translating the seven empirical findings into actionable practice domains. Each finding identified a specific relational dynamic or structural challenge; the elements group these findings into intervention-relevant categories that practitioners can assess, target, and evaluate. For example, Findings 1 and 3 (behavioural impacts on relating; bidirectional failure to connect) converge on communication challenges and are addressed through Element 3 (Communication), while Finding 4 (father–son enmeshment) identifies a cohesion-related dynamic addressed through Element 6 (Cohesion and Connectedness).

The model’s scope extends beyond existing parent training programs in several ways. McCrossin, Lach, and McGrath’s [78] content analysis of 22 randomised controlled trials identified five thematic areas across parent training programs for children with neurodisabilities: child skill enhancement, parenting as enacted, parenting as experienced, disability-specific parenting, and parent–child relationships. The present model addresses all five of these areas but adds three dimensions absent from most existing programs: (a) whole-family intervention across multiple subsystems (couple, sibling, parent–child) rather than targeting parent–child dyads alone; (b) explicit attention to family-level constructs such as cohesion, flexibility, and communication drawn from established family systems models [37, 86], and (c) integration of autism-specific theoretical frameworks (monotropism, double empathy problem) that reframe intervention targets in neurodiversity-affirming terms.

Model Overview and Guiding Principles

The central tenet of the model is a collaborative approach to practice, enabling families to have choice and control over how they receive intervention, what the intervention addresses, and the supports they engage with [32]. This person-centered approach positions families as equal partners in planning, developing, and monitoring services.

The model is positioned from a social view of disability, recognizing that social environments can disable or enable autistic individuals to participate fully [2, 50]. In practice, this means creating encouraging therapeutic spaces that accommodate autistic adolescents’ communication preferences and consistently upholding disability rights, justice, and respect for persons with disabilities [56].

Given the heterogeneity of autism and diversity inherent in families, the model does not propose an exact hierarchy of principles, approaches, or strategies. Rather, it offers a reflective, flexible, and dynamic blueprint for action, describing what happens in practice in a general way to guide decision-making and assist practitioners in articulating key concepts with families. Appendix A provides detailed operationalised strategies for each of the six elements of the family-based practice model for enhancing relationships in families of autistic adolescents.

Element 1: Active Participation

Aligned with Finding 7 (Lack of Suitable Supports and Exclusion).

Families in the empirical research lacked access to autism-knowledgeable professionals, suitable supports, and affordable respite. This element addresses the need for practitioners with clinical experience working with autistic adolescents and their families.

Core Strategies:

Psychoeducation. Facilitate discussion with families to explore autism and what it means for the autistic adolescent, using terminology families prefer (e.g., autism, autism spectrum condition, neurodivergence). Work alongside families to explore what these terms mean for the autistic adolescent and family unit collectively. Remain sensitive to emotions these discussions generate, including shame, guilt, or remorse that families may experience related to societal stigma around disability and diagnosis.

Empathic listening. Utilize well-developed empathy and emotional skills to attend to each family member’s experience. Manage emotional regulation when families discuss sensitive topics. Recognize that practitioners’ ability to remain present and attuned, models healthy emotional regulation for families.

Knowledge building. Ensure practitioners maintain current, evidence-based understanding of autism in adolescence, including how autistic adolescents’ monotropic cognitive style shapes sensory sensitivities, communication differences, executive functioning differences, and co-occurring support needs. Where practitioners lack autism expertise, collaborate with autism specialists or facilitate referrals.

This element draws on client-centered principles [97] emphasizing unconditional positive regard, empathic understanding, and congruence. It recognizes that families’ negative experiences with professionals lacking autism knowledge create barriers to engagement and trust. From a family systems perspective, Carr’s [22] comprehensive review demonstrates that the therapeutic alliance between practitioner and family is a consistent predictor of outcome across systemic interventions for child-focused problems. Gunty [48] reinforces this point, noting that when families do not engage in home components of interventions, clinicians should consider whether the assignment overwhelms the family’s current resources rather than labelling the family as ‘non-compliant’, an insight that directly informs how practitioners implementing this element should approach family engagement.

Element 2: Autonomy and Inclusion

Aligned with Finding 6 (Family Identity and Social Buffering).

Families in the research fell into two groups: those embracing neurodiversity-affirming identities (primarily multiplex families) and those minimizing community engagement due to fear of stigma. This element addresses how family identity formation affects well-being and connectedness.

Core Strategies:

Promoting shared understanding. In families where members hold similar views of autism, reinforce this shared perspective as a source of cohesion and psychological well-being [53, 104]. In families with divergent views, facilitate open dialogue between autistic adolescents and parents using advanced active listening and open-ended questions delivered respectfully and non-judgmentally.

Supporting neurodiversity-affirming environments. For families holding deficit views of autism, work to develop inclusive, strengths-based family environments. Increase awareness of how autism is perceived and help positively reorient attitudes. Frame contributing factors to community avoidance, including interpersonal dynamics, social determinants, and cultural influences.

Reinforcing parental buffering. Support parents’ capacity to buffer against negative external responses by providing behavioral and social supports that reinforce parental confidence. Work collaboratively to develop, implement, and adapt service delivery through an evolving practice framework suited to changing needs.

Attending to minority members. In multiplex families where most members are autistic, recognize potential challenges for non-autistic members to develop positive identity and maintain meaningful relationships [44, 45]. Work collaboratively to identify supports promoting sense of belonging. Use expert knowledge to facilitate access to suitable services, such as support groups for family members of neurodivergent individuals.

Social Identity Theory [106] explains how group membership influences self-concept and well-being. Strong in-group identity among multiplex families promotes cohesion and buffers against stigma. The construct of “social buffering” [25] explains how supportive environments mitigate stress impacts. This element also engages Walsh’s [118] family resilience framework at the level of belief systems—specifically, how families make meaning of adversity and whether they contextualise autism through a strengths-based or deficit-based lens. Walsh [118] identifies “making meaning of adversity” as a key resilience process involving normalising and contextualising distress, maintaining a positive outlook, and finding purpose through challenge. For families of autistic adolescents, neurodiversity-affirming identity formation represents a specific instantiation of this meaning-making process. In Circumplex Model terms, families with strong shared identity tend to function within the balanced cohesion range (connected), while identity conflict may push families toward disengaged functioning [86].

Element 3: Communication

Aligned with Findings 1 and 3 (Behavioral Impacts; Bidirectional Failure to Connect).

Families experienced difficulties with socio-emotional reciprocity, misreading emotions and social cues, and bidirectional failures of empathy. Practitioners should be aware that difficulties with Object Permanence (OP)—the cognitive understanding that people, plans, and situations continue to exist even when not directly perceived—can be misinterpreted as lack of empathy or caring [69]. Within monotropism theory, this phenomenon has been theorised as relating to differences in “object permanence” [69]—not in the Piagetian sensorimotor sense, but as an extension describing how monotropic attention allocation may affect the mental representation of people, plans, and situations that are not currently the focus of attention [70]. When attention is captured by immediate interests or demands, connection to absent others may temporarily recede, not because the relationship lacks importance, but because monotropic attention operates differently from polytrophic attention systems.

This theoretical framework, which requires further empirical investigation, offers practitioners a non-deficit explanation for behaviours that family members may otherwise interpret as indifference, forgetfulness, or lack of care. This attention-based explanation aligns with executive function research demonstrating working memory differences in autism [52] and challenges with sustained attention to non-immediate stimuli.

Practice in this element involves psychoeducation about attention differences and practical strategies such as visual reminders, scheduled check-ins, and explicit communication about the distinction between “out of awareness” and “not valued.” For example, an autistic adolescent may show little interest in a sibling’s important life events (exams, competitions, friendship difficulties) when not physically present for them. While this may appear uncaring, it may reflect OP challenges—when the sibling and their concerns are not immediately visible, maintaining awareness of their ongoing emotional experiences becomes difficult, especially when the adolescent’s attention is captured by immediate interests or activities. This distinction has significant implications for family relationships: what appears to be callousness, or disregard may actually reflect a cognitive processing difference rather than an emotional deficit. Families benefit from understanding that autistic individuals experience empathy—indeed, often intensely—but may process social and relational cues differently due to OP and monotropic attention patterns. This element addresses communication challenges across family dyads.

Core Strategies:

Addressing autism-related communication differences. Work with autistic adolescents and family members (alongside autism specialists if needed) to reduce frustration from miscommunications and address tension or conflict miscommunication creates. Explore specific challenges including difficulty reading body language, expressions of emotions, and social cues, as well as impacts of restrictive and repetitive interests on conversations. From a monotropism perspective, what diagnostic criteria term “restricted and repetitive interests” are better understood as passionate interests—areas where attention flows intensely and engagement is most authentic [70]. These interests represent not pathology but the natural expression of monotropic cognition. Crucially, flow states achieved during engagement with passionate interests may represent the times when autistic individuals feel most connected to themselves and, potentially, to others who share or respect those interests [94]. Rather than viewing interests as barriers to relationship or targets for reduction, practitioners can help families recognise passionate interests as potential bridges to connection—opportunities for shared engagement, mutual respect, and authentic relating. When family members engage with an autistic adolescent through their interest rather than attempting to redirect attention away from it, connection becomes possible on terms that honour the adolescent’s cognitive style.

Promoting open communication. Support families to develop problem-solving skills and communication patterns emphasizing open rather than closed communication [19]. Help families move toward collective understanding of clear, accepted communications about emotions, needs, and behaviors. Recognize that subtle differences in how individuals communicate can lead to misunderstandings generating ambiguity, conflict, or disengagement. Approximately 50% of autistic individuals experience alexithymia—difficulty identifying and describing emotions—which requires adapted communication approaches [64]. Rather than assuming emotional awareness, clinicians should support multiple pathways for emotional expression, including describing physical sensations, using visual aids, and validating needs-based communication [10, 20].

Utilizing advanced listening skills. Display understanding of non-verbal communication to increase deeper understanding and fuller communication of factual and emotional content. Facilitate open, direct dialogue between family dyads and the family unit to reduce bidirectional failure of empathy [54, 82], consistent with the double empathy problem theory.

Shifting focus from identified individual. Encourage shift from viewing the autistic adolescent as the identified individual toward recognizing that all family members can misunderstand each other. Frame communication challenges as bidirectional rather than locating difficulty solely with the autistic individual.

Bowlby’s [19] attachment theory emphasizes open communication about emotions and needs as foundational for secure relationships. The “double empathy problem” [80] recognizes that communication breakdowns occur bidirectionally between autistic and non-autistic individuals, not solely due to autistic social communication differences. The Circumplex Model positions communication as the “facilitating dimension” that enables families to adjust their levels of cohesion and flexibility [86]. Positive communication skills—listening, speaking, self-disclosure, clarity, continuity tracking, and respect—help balanced families maintain functional patterns, while poor communication impedes movement and increases the likelihood that unbalanced systems remain extreme [86]. The McMaster Model similarly identifies communication as one of its six core dimensions, distinguishing between clear versus masked and direct versus indirect communication patterns, and positing that the more clear and direct the overall family communication pattern, the more effective the family’s functioning [37]. For families with autistic members, this element must account for monotropic attention allocation: conversation requires simultaneous attention to content, facial expressions, tone, and turn-taking, which may exceed monotropic processing capacity (Murray et al., 84). Practitioners should therefore adapt communication strategies to accommodate attentional bandwidth differences, such as reducing simultaneous processing demands, allowing extended response time, and using interest-based conversation bridges.

Element 4: Psychoeducation

Aligned with Findings 2 and 3 (Coping Methods; Bidirectional Failure to Connect).

Families used various coping strategies—some adaptive, some maladaptive—and experienced ambiguous loss and grief in relationships. This element provides psychoeducation to support adaptive coping and address loss.

Psychoeducation must also account for alexithymia—difficulty identifying and describing one’s own emotions—which occurs at elevated rates among autistic individuals [64]. Practitioners cannot assume that an autistic adolescent will readily identify their emotional states or connect internal sensations to emotional labels. This relates to interoception, the awareness of internal bodily signals such as hunger, pain, or emotional arousal,monotropic processing may mean that attention is not distributed across internal signals in the same way as for polytropic individuals [70]. Practical strategies include: using concrete, observable descriptors rather than abstract emotion words,connecting emotions to physical sensations or situations; using visual scales or body maps; and accepting that emotional expression may look different from neurotypical expectations. Families can be supported to recognise that difficulty naming emotions does not indicate absence of emotion—autistic adolescents may experience emotions intensely while lacking the interoceptive awareness or vocabulary to communicate them.

Psychoeducation about sensory sensitivities should be grounded in understanding monotropism. Because monotropic attention channels intensify current focus, sensory input within that channel may be experienced with heightened intensity, while input outside the attention tunnel may go unnoticed entirely (Murray et al., 84). This explains why an autistic adolescent might be overwhelmed by a sound that others barely notice (hyper-sensitivity within the attention focus) while simultaneously appearing oblivious to someone calling their name (hypo-awareness outside the focus). Families benefit from understanding this as an attentional pattern rather than selective hearing or deliberate ignoring.

Core Strategies:

Addressing ambiguous loss. Facilitate discussion about behaviors and patterns contributing to ambiguous relationships, unclear communications, and stress. Draw on the construct of ambiguous loss [13,14,15] to guide intervention, recognizing families experience psychological absence despite physical presence. Support identification of strategies promoting adaptive patterns including conflict resolution, problem-solving, and enhanced coping ability [116].

Processing grief and loss. Help families work through periods of reframing expectations as part of grieving the loss of normative family experiences. Explore grief from autistic adolescents’ perspectives, recognizing they experience social and emotional disconnectedness from parents despite strong desires to connect. Support identification of strategies promoting reciprocal awareness that this loss may be a unifying experience.

Promoting adaptive coping. Encourage approach or action strategies, problem-focused strategies, and cognitive and meaning-making strategies rather than avoidant behaviors like social isolation or emotional withdrawal [76, 79, 83]. Implement cognitive restructuring [43] to help family members identify and challenge maladaptive thoughts.

Managing sibling conflict. Support strategies teaching behavioral and social skills and self-regulatory skills to siblings [65]. Facilitate open dialogue exploring feelings of guilt, stress, and anxiety for parents responding to distress-driven behaviors and sibling conflict while maintaining relationship balance.

Enhancing resilience. Build on families’ existing resilience factors including supportive and appreciative interactions, open and positive communication patterns, committed relationships, teamwork, problem-solving, flexibility with each member’s needs, spending time together, positive outlook, and established routines [5, 47, 60].

Ambiguous loss theory [14] explains psychological distress from unclear or incomplete losses, a dynamic particularly relevant for families who grieve the expectations they held for their autistic child while simultaneously celebrating who their child is. Walsh’s [118, 119] family resilience framework identifies protective factors enabling families to navigate adversity, with particular emphasis on how families that engage in collaborative meaning-making around their experiences emerge more resilient. Gunty’s [48] systematic review extends this to ASD-specific contexts, demonstrating that meaning-making is a core element of the family resilience process and that clinicians should consider how interventions support or hinder families’ capacity to balance stressors against available resources. Cognitive-behavioral approaches address maladaptive thought patterns and avoidant coping [7]. This element’s psychoeducation content—particularly around alexithymia, interoception, and sensory processing within a monotropism framework—provides families with the knowledge base necessary for the meaning-making processes that Walsh [118] and Gunty [48] identify as central to resilience.

Element 5: Recognition and Awareness

Aligned with Finding 5 (Sisters as Caregivers).

All sisters of autistic brothers with intellectual disability assumed substantial caregiving roles, creating role ambiguity, boundary confusion, and isolation. This element addresses role clarity and boundary issues.

Core Strategies:

Addressing role conflict. Recognize that role conflict and lack of clarity increase depression and anxiety risk [16]. Facilitate labeling and discussion of role difficulties without attributing blame [9]. Enable siblings—particularly sisters—to explore present and future caregiving concerns without guilt [105].

Monitoring gendered caregiving. Remain cognizant of gendered caring patterns where sisters disproportionately assume caregiving duties. Closely monitor sisters’ caring load and associated pressure. Use practitioner sensitivity around role acceptance coupled with resilience-enhancing strategies as central therapeutic components supporting ongoing ability to cope.

Advocating for respite. Actively advocate for regular respite for sister siblings away from caring duties and role expectations. Use knowledge of suitable agencies to support applications for household support and respite funding. Consider family functioning in single-parent households where siblings’ caring duties likely increase further (Finding 5).

Clarifying boundaries. Facilitate open dialogue between parents and siblings addressing family structural issues including boundary issues or role ambiguities. Use boundary ambiguity construct [17] to guide intervention, supporting identification of strategies promoting alignment in family subsystems toward balance between open and closed boundaries. Help family members distinguish clearly between family roles, such as blurred divisions between being a sibling and being a caregiver [27].

Addressing emotional entanglement. Work to address complexities of emotional entanglement potentially occurring between primary caregiver and autistic child in parent–child dyads due to overly open emotional boundaries—where insufficient differentiation exists between caregiver and child emotional states, such that the caregiver’s mood, identity, and daily functioning become excessively intertwined with the child’s wellbeing, and the child in turn absorbs parental anxiety. This enmeshment can create feedback loops that intensify distress for both parties.

Boundary ambiguity theory [17] explains how unclear role definitions create psychological distress. Family systems theory [81] emphasizes appropriate boundaries between subsystems. Research on gender and caregiving documents disproportionate burden on daughters [55]. The McMaster Model’s [37] roles dimension is directly relevant here: it defines family roles as the repetitive patterns of behaviour by which individuals fulfil family functions, and distinguishes between necessary family functions and the allocation of responsibility for these functions. Finding 5’s identification of sisters assuming caregiving roles represents problematic role allocation in McMaster terms, where necessary family functions are being fulfilled by a family member whose own developmental needs are compromised in the process. Epstein et al. (1978) further note that roles must be assessed in terms of both allocation and accountability, whether functions are clearly assigned to individuals and whether mechanisms exist to ensure they are fulfilled. This element’s strategies around role clarification and boundary setting operationalize McMaster assessment of the roles dimension within the specific context of sibling caregiving in autistic families.

Element 6: Cohesion and Connectedness

Aligned with Finding 4 (Father-Son Enmeshment).

Fathers and sons with autism showed mirrored behaviors and emotional entanglement due to undefined boundaries. This element promotes healthy balance between connectedness and separateness.

Core Strategies:

Providing father-oriented supports. Establish father-focused interventions acknowledging fathers as primary caregivers. Facilitate open dialogue between fathers of autistic children in father-focused parenting groups. Work collaboratively to develop strategies strengthening family relationships and learning necessary skills to address emotional and physical parenting challenges (Finding 4).

Balancing connectedness and separateness. Promote balance between healthy connectedness and healthy separateness in father-autistic child relationships, particularly important when fathers adopt multiple roles (caregiver, friend, teacher, caseworker/advocate). Address potentially increased prospects for emotional entanglement and psychological fusion between parent and child.

Addressing enmeshment. Choose strategies to address enmeshment and emotional entanglement in parent–child relationships, including encouraging more independence and autonomy for autistic adolescents, working toward balance of healthy connectedness and healthy separateness. Recognize that enmeshed relationships, while appearing to show affection and care, may impede individuality processes and affect psychosocial development [4].

Facilitating external supports. Use knowledge of suitable agencies to provide referrals to external peer support groups for young people and carer support groups for parents. External support groups serve as helpful outlets for emotional and social needs and are particularly important for families with limited formal and informal support networks who often rely greatly on extended family members [72].

Recognizing resilience and growth. While acknowledging challenges and mental health risks, encourage families to see themselves as capable, strong, and successful in exhibiting resilience and growth while managing diverse stressors. Draw attention to positive changes including newly acquired outlooks or appreciation of life, increased family cohesion, and development of stronger family relationships.

Structural family therapy [81] emphasizes appropriate boundaries and subsystem functioning. Enmeshment theory explains how overly close relationships with undefined boundaries impede individuation [4]. Post-traumatic growth frameworks recognize positive changes emerging from adversity [107]. The Circumplex Model’s [86] cohesion dimension provides the most direct theoretical connection for this element. Olson defines family cohesion as the emotional bonding that family members have toward one another, ranging from disengaged (very low) through separated and connected (balanced) to enmeshed (very high). The father–son enmeshment identified in Finding 4 corresponds to unbalanced cohesion at the enmeshed extreme within a specific subsystem: an extreme amount of emotional closeness where individuals are very dependent on each other and reactive to one another, with a lack of personal separateness [86]. Olson’s treatment planning framework proposes that for enmeshed families, intervention should support movement toward balanced cohesion, not toward disengagement, but toward connected or separated functioning where members can experience and balance togetherness and independence [86]. This directly informs this element’s core strategy of promoting balance between healthy connectedness and healthy separateness. Importantly, Olson [86] notes that the Circumplex Model is sensitive to cultural diversity, what appears enmeshed by one cultural standard may be functional in another. Practitioners should therefore assess enmeshment patterns in context rather than applying universal thresholds, attending to whether the closeness serves adaptive functions or impedes individuation and development.

Implementation of the Practice Model

Target Populations and Settings

The practice model is designed for families with autistic adolescents (ages 12—19 years) and their family members (parents, siblings). The model requires adaptation to diverse family contexts, including culturally and linguistically diverse (CALD) families and families with gender-diverse members. Cultural factors influence how autism is understood, whether and how diagnosis is sought, family communication norms, and acceptable forms of support [31]. Gender fluidity and transgender identity intersect with autism at elevated rates [120], and autistic adolescents exploring gender identity may face compounded challenges in family relationships, particularly where gender norms are strongly held. Research indicates that autistic transgender individuals experience multiple layers of camouflaging demands—managing autistic traits, gender presentation, and navigating both neuronormative and cisnormative expectations [49]. Practitioners must create space for these intersecting identities and ensure the model’s application does not assume cisgender or culturally homogeneous family structures.

The practice model is applicable across various practice settings including clinical social work and family therapy practices providing counseling or therapeutic contexts, community mental health services offering family-based interventions, autism-specific service agencies providing comprehensive family support, school-based family support programs coordinating with educational settings, and disability support services funded through mechanisms like Australia’s NDIS. Practitioners implementing the model should include social workers, family therapists, psychologists, occupational therapists, and other professionals with appropriate training in family systems approaches. Central to practice is working collaboratively on issues identified by families to enhance socio-emotional functioning within social and physical environments [46].

Intervention Structure and Duration

The model does not prescribe exact intervention duration or session length, recognizing these vary based on unique presenting factors of each family, service model and funding structures, practitioner’s theoretical orientation and approach, family preferences and availability, and severity and complexity of relationship challenges.

Sessions might include some or all members of the immediate family unit. Family members should be encouraged to decide who is able and willing to engage, with participation varying across sessions based on needs and preferences. Individual sessions with specific family members (e.g., father-focused groups, sibling support groups) can complement whole-family sessions.

A phased approach is recommended. The assessment phase (2–4 sessions) builds therapeutic alliance, assesses family functioning across the model’s six elements, identifies strengths and challenges, and collaboratively develops goals. This duration is grounded in family therapy literature: Carr’s [22] review of effective systemic interventions documents preliminary engagement and assessment phases as standard components, and Minuchin’s [81] structural family therapy model emphasises the importance of joining with the family system before attempting restructuring interventions. The active intervention phase (8–16 sessions) implements strategies targeting specific elements based on family needs. This range reflects the evidence base for family-based interventions for children with neurodisabilities: McCrossin et al.’s [78] content analysis found that approximately 70% of parent training programme trials involved 5–12 sessions, with 25% involving 13–17 sessions. The wider range proposed here accommodates the model’s whole-family scope, which extends beyond parent training to include sibling subsystems, couple relationships, and cross-subsystem coordination. The consolidation phase (2–4 sessions) reviews progress, strengthens gains, and plans for ongoing support, following standard family therapy practice of reviewing and anticipating future challenges [119]. These session ranges are indicative rather than prescriptive, and should be adapted to individual family needs and service contexts. Some families may require longer engagement,others may benefit from briefer, more focused intervention followed by periodic check-ins.

Assessment and Evaluation

Practitioners should assess family functioning across domains targeted by the model: communication patterns (open vs. closed; direct vs. ambiguous; verbal and non-verbal), role structure (clarity vs. ambiguity; balance vs. boundary violations; age-appropriate expectations), cohesiveness (healthy connectedness vs. enmeshment; healthy separateness vs. disengagement), adaptive patterns (problem-solving effectiveness; conflict resolution skills; coping strategies employed), family identity (neurodiversity-affirming vs. deficit-based; sense of belonging; social connectedness), and external support access (availability of respite; quality of professional support; community inclusion).

Assessment should be ongoing throughout intervention, using both formal measures (where appropriate and family-consented) and qualitative observation. Evaluation focuses on family-identified goals rather than imposing external benchmarks.

Cultural Responsiveness and Adaptation

While the model was developed with Australian families primarily of white, university-educated backgrounds, practitioners must adapt implementation to diverse cultural contexts. Cultural beliefs, values, and stigma significantly shape how families understand autism, access support, and navigate relationships.

Culturally responsive practice includes exploring cultural beliefs about disability, family roles, and help-seeking; recognizing that communication norms, emotional expression, and family structures vary across cultures; adapting intervention strategies to align with cultural values and preferences; addressing unique barriers faced by culturally and linguistically diverse families; involving cultural brokers or interpreters when language barriers exist; and recognizing intersectional identities (e.g., LGBTQI + autistic youth, Indigenous families). Future research should explicitly examine how cultural factors influence family experiences and intervention outcomes in diverse communities.

Coordination Across Systems

Effective implementation requires coordination across multiple systems affecting families: healthcare (coordinate with medical providers, mental health professionals, and allied health services), education (collaborate with schools to ensure consistent support and reduce school-related stressors), disability services (navigate funding systems such as NDIS in Australia and coordinate service access), and community organizations (connect families with autism advocacy groups, peer support networks, and recreational programs). Practitioners may need to serve as care coordinators, ensuring families receive comprehensive, integrated support rather than fragmented services.

Discussion

This article presents an evidence-informed practice model for enhancing family relationships and promoting connectedness in families of autistic adolescents. The model addresses recognised gaps in holistic family support interventions by providing practitioners with theoretically grounded, empirically informed strategies for assessment, case management, therapeutic work, and group programs. The following discussion is organised around three themes: (1) the nature and scope of the model’s theoretical contribution, (2) key implications for practice, and (3) considerations for diverse family contexts alongside the model’s limitations and directions for future research.

Theoretical Contributions: Synthesis Rather than Novelty

The conceptual framework’s contribution lies not in introducing new theoretical constructs but in synthesising established frameworks—family systems theory [81], ambiguous loss theory [14], the Circumplex Model of Marital and Family Systems [86], Walsh’s [118, 119] family resilience framework, the McMaster Model of Family Functioning [37], social identity theory [106], and monotropism (Murray et al., 84)—into an integrated lens for understanding and intervening in families of autistic adolescents. Individually, each of these theoretical traditions have been applied to family research, disability contexts, or autism specifically. What has been absent is a framework that brings them together in a manner that is both neurodiversity-affirming and oriented toward whole-family relational intervention.

The disruption–connection continuum proposed in this framework offers a mechanism for explaining how the constructs from these different traditions interact within families. The Circumplex Model’s dimensions of cohesion and flexibility [86] provide the structural vocabulary for describing where families fall on this continuum: disengaged or enmeshed cohesion, rigid or chaotic flexibility. Walsh’s [118] family resilience framework supplies the process-level understanding of how families move along the continuum, through belief systems, organisational patterns, and communication processes. The McMaster Model [37] offers complementary assessment dimensions (problem-solving, communication, roles, affective responsiveness, affective involvement, behaviour control) that allow practitioners to identify specific areas of family functioning requiring intervention. And monotropism (Murray et al., 84) provides the autism-specific theoretical grounding that existing family systems models lack, explaining why communication, transitions, and attentional demands operate differently in families with autistic members.

This synthesis is consistent with recent calls in the literature for theoretical frameworks that account for the complex, relational, systemic contexts in which families of children with neurodisabilities operate [78]. McCrossin, Lach, and McGrath’s [78] content analysis of parent training programs found that existing interventions’ theoretical underpinnings focused primarily on the individual child or parent, with little acknowledgement of systemic family dynamics. The present model directly addresses this gap by positioning the family system as the unit of analysis and intervention.

Gunty’s [48] systematic review further supports the theoretical approach taken here. Her conceptualisation of family resilience in families of children with ASD as a dynamic process of balancing stressors, resources, and meaning-making parallels the disruption–connection continuum, and her critique that existing resilience research places disproportionate responsibility on families without accounting for contextual constraints aligns with this model’s explicit attention to external factors (stigma, service inadequacy, community exclusion) as modulators of family functioning.

An important theoretical direction for future development concerns the integration of monotropism. While the current model incorporates monotropism at specific points—particularly in explaining communication challenges through the double empathy problem, attention allocation differences, and sensory-relational patterns—it functions additively rather than as the organising principle of the entire framework. Future theoretical work might examine how monotropic attention allocation shapes every dimension of family functioning: how families negotiate whose interests receive attention, how family rituals either accommodate or violate monotropic needs for deep engagement, and how therapeutic interventions either support or disrupt monotropic processing. This deeper integration represents an important direction for advancing neurodiversity-affirming family therapy frameworks, and we encourage other research teams to pursue this line of theoretical development.

Practice Implications

Shifting from individual to family-level intervention. Traditional interventions for autistic individuals focus on skill development or managing areas of difficulty. While important, this approach neglects relational dynamics and family-level functioning. The present model positions the family system as the unit of intervention, recognising that strengthening relationships and promoting connectedness benefits all members, including the autistic adolescent. This orientation is consistent with the substantial evidence base for systemic interventions in child-focused problems documented by Carr [22] and responds to McCrossin and Lach’s [77] finding that parenting programs inconsistently measure family-level outcomes, with general family functioning representing only 31.6% of family-level constructs assessed across 29 studies.

Balancing challenge and strength perspectives. The model acknowledges genuine challenges families face—aggressive behaviours, caregiver exhaustion, role confusion, grief and loss—while emphasising families’ capacities for resilience, growth, and connection [48, 118]. This balanced approach avoids both deficit-focused narratives that pathologise families and overly optimistic accounts that minimise real struggles. Walsh [118] frames adversity as holding potential for relational transformation: families that weather crises together may emerge with strengthened bonds and new competencies.

Addressing external as well as internal factors. Effective intervention cannot focus solely on internal family dynamics. Practitioners must address external barriers including inadequate services, educational system failures, community stigma, and limited respite availability (Finding 7). This may involve advocacy, system navigation, and working to change environments rather than only changing families. Gunty [48] highlights that family resilience research has historically placed the responsibility for resilience on the family itself, without adequately accounting for contextual constraints, a limitation this model seeks to address through its explicit external factors pathway.

Including autistic voices. The empirical research centred autistic adolescents’ perspectives alongside family members’ views. Practice should similarly ensure autistic adolescents are active participants in intervention, not merely present but genuinely included in decision-making about goals, strategies, and evaluation. This requires practitioners to accommodate monotropic processing differences in session design, including providing advance notice of topics, allowing sufficient processing time, and recognising that contributions may take non-verbal or interest-based forms.

Recognising family heterogeneity. Families vary dramatically—multiplex versus single-diagnosis families; those with neurodiversity-affirming versus deficit-based identities; families where autism co-occurs with intellectual disability versus autism alone. The Circumplex Model’s sensitivity to cultural and contextual diversity is relevant here: Olson [86] notes that what appears to be extreme functioning may be normative and functional within particular cultural or religious contexts. The model’s flexibility allows adaptation to diverse family presentations rather than imposing prescriptive approaches.

Considerations for Diverse Family Contexts, Limitations, and Future Directions

Family structure and composition. The model was developed primarily from research with two-parent families. Single-parent families face distinct structural challenges—sole decision-making responsibility, financial constraints, limited respite opportunities—that may require substantial adaptation of practice elements. Similarly, stepfamilies, families with separated or divorced parents co-parenting an autistic adolescent, and families headed by grandparents represent significant proportions of families raising autistic children, and the model’s applicability to these contexts has not been examined. In Circumplex Model terms [86], single-parent families may present with different baseline patterns of cohesion and flexibility than two-parent families, and practitioners should assess accordingly rather than applying norms derived from two-parent research. Future research should explicitly examine how the model translates to diverse family structures and what modifications optimise effectiveness.

Multiplex versus simplex families. The empirical findings revealed important differences in family identity formation between multiplex families (where multiple members are autistic) and simplex families (where one member is autistic). Multiplex families more readily embraced neurodiversity-affirming identities that promoted cohesion and social buffering, while simplex families were more variable. Practitioners should recognise these identity dynamics and attend to minority members in each context—non-autistic members in multiplex families may need support developing positive identity and maintaining meaningful relationships, while autistic members in simplex families may need support connecting with autistic community and culture outside the family unit.

Co-occurring intellectual disability. The model was developed from studies with inconsistent intellectual disability (ID) representation. While Finding 5 (sisters as co-carers) emerged from families where autistic members had moderate-severe ID, most other findings came from samples without ID or with mild ID only. The model has not been validated for families where autism co-occurs with moderate-severe ID, and substantial modifications would likely be necessary given different support needs, caregiving demands, and family stressors associated with ID co-occurrence [115]. Future research should explicitly examine this model’s applicability and necessary adaptations for this population, including perspectives from non-speaking autistic individuals.

Gender and enmeshment patterns. Finding 4 identified father–son enmeshment as a distinct relational pattern. In Circumplex Model terms, this represents unbalanced cohesion at the enmeshed extreme within a specific subsystem [86]. However, our research examined father–son dyads specifically and did not systematically study other parent–child gender combinations. Whether mother–son, mother–daughter, or father–daughter dyads show similar patterns remains unknown. Practitioners should apply the assessment questions in Element 6 (Cohesion and Connectedness) to all parent–child combinations, recognising that gendered socialisation patterns shape how closeness and separateness are experienced and expressed across dyads. Systematic examination of enmeshment across all gender combinations would significantly advance understanding.

Cultural responsiveness. The model was developed with Australian families of predominantly white, university-educated backgrounds. Olson [86] notes that the Circumplex Model is sensitive to ethnic and cultural diversity: families from collectivist cultures may normatively function at cohesion levels that would appear enmeshed by individualist standards, and rigid family structures may be functional within religious or cultural groups that have normative expectations supporting them. Practitioners adapting this model across cultural contexts must explore cultural beliefs about disability, family roles, and help-seeking, recognise that communication norms, emotional expression, and family structures vary across cultures; and address unique barriers faced by culturally and linguistically diverse families, including intersectional identities (e.g., LGBTQI + autistic youth, Indigenous families). Future research should explicitly examine how cultural factors influence family experiences and intervention outcomes in diverse communities.

Methodological limitations. Several methodological limitations warrant acknowledgement. The empirical foundation reflects a specific time point among a relatively small group of families (N = 18 families, 44 participants) drawn from a single geographic area and deriving from a single researcher’s qualitative program. While findings converge with broader autism family research and are grounded in established theoretical frameworks [22, 48, 86, 118], generalisability beyond the specific study context remains uncertain. The practice model was developed primarily from research findings rather than through co-design with service providers, and families experiencing the greatest relationship difficulties may have been less likely to participate.

Untested model. The model has not been empirically tested. While grounded in research evidence and aligned with established practice frameworks, its effectiveness remains unknown. Future research should evaluate outcomes including family relationship quality and satisfaction, communication effectiveness, caregiver well-being and stress levels, sibling adjustment, autistic adolescents’ sense of belonging and family connection, and family resilience and cohesion. Rigorous evaluation should include randomised controlled trials comparing the model to standard practice, qualitative studies examining families’ experiences with the intervention, and implementation research addressing barriers and facilitators to model adoption. Validated family assessment instruments such as FACES IV [87] and the McMaster Family Assessment Device [38] may be suitable for baseline and outcome measurement.

Developmental scope. The model focuses on families of adolescents (ages 12–19). Whether and how it applies to families with younger autistic children or autistic adults requires investigation. The developmental period of adolescence brings unique challenges—identity formation, increasing autonomy, peer relationships—that may necessitate different intervention approaches than other life stages.

Goal alignment. The model emphasises relationship enhancement and connectedness promotion. While these are important outcomes, families may prioritise other goals such as managing specific behaviours, accessing services, or navigating transitions. Practitioners should collaboratively identify goals with families rather than imposing relationship-focused objectives when other needs are paramount.

Conclusion

This practice model offers practitioners a comprehensive, evidence-informed framework for supporting families of autistic adolescents. By attending to both disruptive factors that create disconnection and connective factors that promote bonding, while addressing external barriers to family well-being, the model provides actionable guidance for intervention across multiple family domains. The model’s integration of established family systems frameworks—the Circumplex Model [86], Walsh’s [118] family resilience framework, and the McMaster Model [37]—with autism-specific theoretical perspectives including monotropism (Murray et al., 84) and the double empathy problem [80] represents a synthesis designed to bridge the gap between family therapy traditions and neurodiversity-affirming practice.

Translating research findings into practice is inherently complex, and this model is offered as a starting point for clinical application and empirical evaluation, not as a finished product. Its effectiveness awaits rigorous testing across diverse family contexts, and its theoretical integration, particularly regarding monotropism, invites further development by researchers and practitioners committed to advancing family-centred, neurodiversity-affirming support.
