Common Intersection of Autism and Gender Diversity in Youth: Clinical Perspectives and Practices

The missing clinical guidance: a scoping review of care for autistic transgender and gender-diverse people

The co-occurrence of autism and gender diversity has been increasingly studied in the past decade. It is estimated that ∼11% of transgender and gender-diverse (TGD) individuals are diagnosed with autism. However, there is insufficient knowledge about appropriate gender-related clinical care for autistic TGD individuals. We performed a scoping review of current clinical guidance for the care of TGD individuals to identify what was said about autism. Clinical guidance documents were searched in PubMed, Web of Science, Google Scholar, Embase, Guidelines International Network, and TRIP medical database, as well as reference mining and expert recommendation. Evidence was synthesised by narrative synthesis, recommendation mapping, and reference frequency analysis. Out of the identified 31 clinical guidance documents, only eleven specifically mentioned the intersection between autism and TGD. Key concepts among the available recommendations included advocating for a multidisciplinary approach; emphasising the intersectionality of autism and gender-diverse experiences during assessments; and-importantly-recognising that autism, in itself, does not serve as an exclusion criterion for receiving gender-related care. However, detailed and practical clinical guidance is lacking due to a gap in evidence. Empirical research into the care experiences and outcomes of autistic TGD individuals using a developmental, lifespan, and strengths-based approach is needed to generate evidence-informed and tailored guidance.

Gender diversity is correlated with dimensional neurodivergent traits but not categorical neurodevelopmental diagnoses in children

BACKGROUND

Gender clinic and single-item questionnaire-based data report increased co-occurrence of gender diversity and neurodevelopmental conditions. The nuances of these associations are under-studied. We used a transdiagnostic approach, combining categorical and dimensional characterization of neurodiversity, to further the understanding of its associations with gender diversity in identity and expression in children.

METHODS

Data from 291 children (Autism N = 104, ADHD N = 104, Autism + ADHD N = 17, neurotypical N = 66) aged 4-12 years enrolled in the Province of Ontario Neurodevelopmental Network were analyzed. Gender diversity was measured multi-dimensionally using a well-validated parent-report instrument, the Gender Identity Questionnaire for Children (GIQC). We used gamma regression models to determine the significant correlates of gender diversity among age, puberty, sex-assigned-at-birth, categorical neurodevelopmental diagnoses, and dimensional neurodivergent traits (using the Social Communication Questionnaire and the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Rating Scales). Internalizing and externalizing problems were included as covariates.

RESULTS

Neither a categorical diagnosis of autism nor ADHD significantly correlated with current GIQC-derived scores. Instead, higher early-childhood dimensional autistic social-communication traits correlated with higher current overall gender incongruence (as defined by GIQC-14 score). This correlation was potentially moderated by sex-assigned-at-birth: greater early-childhood autistic social-communication traits were associated with higher current overall gender incongruence in assigned-males-at-birth, but not assigned-females-at-birth. For fine-grained gender diversity domains, greater autistic restricted-repetitive behavior traits were associated with greater diversity in gender identity across sexes-assigned-at-birth; greater autistic social-communication traits were associated with lower stereotypical male expression across sexes-assigned-at-birth.

CONCLUSIONS

Dimensional autistic traits, rather than ADHD traits or categorical neurodevelopmental diagnoses, were associated with gender diversity domains across neurodivergent and neurotypical children. The association between early-childhood autistic social-communication traits and overall current gender diversity was most evident in assigned-males-at-birth. Nuanced interrelationships between neurodivergence and gender diversity should be better understood to clarify developmental links and to offer tailored support for neurodivergent and gender-diverse populations.

Gender diversity in autistic and neurotypical youth over adolescence and puberty: A longitudinal study

Recent research in autism spectrum disorder (ASD) has suggested a higher prevalence of gender diversity in individuals diagnosed with ASD. Adolescence is a critical period for the consolidation of gender identity, yet the extent to which the experience of gender diversity is stable over adolescence and puberty in autistic youth is poorly understood. The aim of the study was to examine the consistency of gender diversity using the gender diversity screening questionnaire for self- and parent-report of youth (GDSQ-S, GDSQ-P) over a four-year longitudinal study of pubertal development in youth with ASD (N = 140, 36 assigned-female-at birth (AFAB)) and typical development (TD, N = 104, 58 assigned-male-at-birth [AMAB]) and their parents. The extent to which diagnosis (ASD vs. TD), assigned sex (AFAB vs. AMAB) and developmental level (age, puberty) predict GDSQ trajectory over time was explored. There was a significant diagnosis by sex-assigned-at-birth by age interaction for GDSQ-S Gender Diversity, p = 0.002, showing higher scores in autistic AFAB youth over adolescence, and TD AFAB showing initially lower, then increasing levels over adolescence. For GDSQ-P, Gender Incongruence was significantly different between the groups, p = 0.032, showing higher incongruence for autistic AFAB around age 10, decreasing between age 12-14 before increasing again, while TD AFAB evidence the inverse trend. AMAB trends were stable. The significant diagnostic, developmental and sex-based differences indicate AFAB youth experience greater gender diversity that evolves over development. Findings suggest gender identity formation is nuanced and may be influenced by pubertal progression, hormonal patterns, and psychosocial factors. Results underscore the need for enhanced understanding of the unique, dynamic profiles of females-assigned-at-birth.

A comparison of gender diversity in transgender young people with and without autistic traits from the Trans 20 cohort study

Background

There is an elevated co-occurrence of autism in trans individuals, with recent meta-analyses suggesting that 11% of trans individuals are autistic. The presence of autism in trans young people can create clinical challenges by adding complexity to the presentation, assessment and management of those presenting to gender clinics. Although many trans young people display traits of autism, how these traits relate to the nature of their gender diversity is unclear.

Methods

This study compared gender identity, gender expression and gender dysphoria (GD) in trans young people with and without autistic traits. Baseline data from a cohort study of trans children and adolescents who first attended the Royal Children's Hospital Gender Service (Victoria, Australia) between February 2017 and January 2020 were analysed cross-sectionally. Autistic traits were assessed via the Social Responsiveness Scale-2. Gender was assessed using tools that measure gender identity, social transition, GD, body dissatisfaction, voice dysphoria, and chest dysphoria.

Findings

522 participants were included, of whom 239 (45.8%) exhibited autistic traits (SRS total T-score ≥60). Those with and without autistic traits were similar in their age (mean (SD) age 14.0 (2.9) and 13.1 (3.6) years respectively) and gender identity: the majority (73.7% (n = 174) and 70.5% (n = 198) respectively) identified in a binary way. Higher rates of social transition (specifically, changing pronouns) were noted in those with autistic traits (Difference in proportion 11.7, 95% confidence interval [CI] 2.4-21.1, p = 0.014). GD was high in both groups with ∼95% displaying clinically relevant levels of GD. Chest dysphoria was similar between groups, while voice dysphoria was higher in those with autistic traits (standardised mean difference [SMD] = 0.3, 95% confidence interval [CI]: 0.1-0.5 p = 0.00087). Dissatisfaction with secondary gendered characteristics (SMD = 0.3, CI: 0.1-0.5 p = 0.0011) and hormonally unresponsive body characteristics (SMD = 0.2, CI: 0.1-0.4 p = 0.016) was higher in trans young people with autistic traits.

Interpretation

The similarly high severity of GD in those with and without autistic traits reinforces the importance of trans young people with and without autistic traits being availed the same opportunities to access gender-affirming care. Subtle differences identified between the groups in other areas of gender diversity suggest trans young people with autistic traits may have distinct needs and that gender-affirming care may need to be tailored accordingly.

Autistic and non-autistic transgender youth are similar in gender development and sexuality phenotypes

Increasing rhetoric regarding the common intersection of autism and gender diversity has resulted in legislation banning autistic transgender youth from accessing standard of care supports, as well as legislative efforts banning all youth gender care in part justified by the proportional over-occurrence of autism. Yet, no study has investigated whether autistic and non-autistic transgender youth present fundamentally different gender-related phenotypes. To address this gap, we extensively characterized autism, gender diversity, and sexuality among autistic and non-autistic transgender binary youth (N = 66, Mage = 17.17, SDage = 2.12) in order to investigate similarities and/or differences in gender and sexuality phenotypes. Neither autism diagnostic status nor continuous autistic traits were significantly related to any gender or sexuality phenotypes. These findings suggest that the developmental and experiential features of gender diversity are very similar between autistic and non-autistic transgender adolescents. Future research is needed to determine whether the similarity in profiles is maintained over time into adulthood.

Supporting the health and wellbeing of trans autistic school-aged youth: a systematic literature review

Introduction : This systematic literature review (SLR) aims to synthesize available research which examines the supports required for trans autistic school-aged youth to improve their mental health, wellbeing, and quality of life. Current literature highlights the need to support this specific school-aged population, but the research that synthesizes the existing limited research is lacking. This SLR brings together existing literature and highlights recommended inclusive interventions, programs, support mechanisms, and protective factors needed to support and promote optimal mental health and wellbeing.

Methods

This review followed the 2020 PRISMA Guidelines and included JBI quality appraisal tools of included studies. Three electronic databases were used, with literature search conducted on 18 July 2023. Literature, including book chapters, were assessed against predetermined inclusion and exclusion criteria, with included studies written in English, online full-text availability, peer-reviewed, and reported data relevant to research question. Abstract, full-text review, and quality appraisal were conducted by three independent reviewers to ensure rigor. Findings from included studies were synthesized using thematic analysis.

Results

Twenty studies were included for final synthesis with five using qualitative methodologies, two case reports, and 13 cross-sectional studies. The final synthesis comprised five themes, indicating therapy should focus on mental health, particularly internalized feelings and emotions that may lead to suicidal ideation without support, whereas interventions should support executive functioning, communication, and socialization. Clinicians should make adaptions to their clinics and practices to support the neurodivergent-related needs of their clients. Schools should work toward having well-articulated and embedded policies supporting gender affirmation and preventing bullying and ostracization to ensure trans autistic youth develop positive health and wellbeing, and overall good quality of life.

Conclusions

In many cases support measures discussed were limited. The complexities of supporting the needs of school-aged trans autistic youth requires further research, specifically focusing on the voices of trans autistic youth.

Mental health challenges faced by autistic people

Mental health challenges impede the well-being of autistic people. This Review outlines contributing neurodevelopmental and physical health conditions, rates and developmental trajectories of mental health challenges experienced by autistic people, as well as unique clinical presentations. A framework is proposed to consider four contributing themes to aid personalized formulation: social-contextual determinants, adverse life experiences, autistic cognitive features, and shared genetic and early environmental predispositions. Current evidence-based and clinical-knowledge-informed intervention guidance and ongoing development of support are highlighted for specific mental health areas. Tailored mental health support for autistic people should be neurodivergence-informed, which is fundamentally humanistic and compatible with the prevailing bio-psycho-social frameworks. The personalized formulation should be holistic, considering physical health and transdiagnostic neurodevelopmental factors, intellectual and communication abilities, and contextual-experiential determinants and their interplay with autistic cognition and biology, alongside resilience. Supporting family well-being is integral. Mutual empathic understanding is fundamental to creating societies in which people across neurotypes are all empowered to thrive.
