[PMID: 38831234 DOI: 10.1007/s10508-024-02896-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 05/08/2024] [Accepted: 05/08/2024] [Indexed: 06/05/2024]
Abstract
This systematic review investigated how studies have measured gender dysphoria (GD) in autistic samples and the impact of using different measures on study results. The literature search identified 339 relevant papers, with 12 of them meeting the inclusion criteria. Results showed that seven different measures of GD characteristics have been used with autistic samples and that the studies consistently reported a greater number of GD characteristics and a greater severity of GD in autistic compared to non-autistic samples. Methodological common practices were found in recruiting participants from clinical settings rather than the general population, having more autistic males than females in the samples, for studies being conducted in Europe, North America, and Oceania, and using single-item measures of GD for samples of autistic children. Issues were identified with study designs and measures of GD, suggesting a need for a more standardized multi-item self-report measure of GD for use in clinical and non-clinical samples across different ages and cultures.

Abstract
LAY ABSTRACT Research has increasingly focused on the intersection between gender diversity and autism. To better understand this literature, this scoping review systematically searched five databases for peer-reviewed literature on gender diversity and autism published between 2018 and 2023. Included studies (N = 84) were of English language, featured original qualitative or quantitative findings, and examined a psychosocial connection between autism and gender spectra variables. Most studies focused on measuring prevalence of autism among gender-diverse individuals. While the overall study rigor was acceptable, weaknesses in measurement, sample selection, and definition of key terms were noted. Promisingly, studies in this area appear to be shifting away from a pathologizing lens and towards research methods that engage in meaningful collaboration with the autistic, gender-diverse community to investigate how to best enhance the quality of life and wellbeing of this population.

Abstract
Autism and gender diversity often intersect. Many transgender youth seeking gender-related medical interventions are autistic. Clinicians serving these youth lack an autism-specific evidence base to guide gender care decisions. At present, care decisions are based on extrapolation of care models from transgender youth samples, generally. At this point, there is no evidence to suggest that autistic youth are likely to experience shifts in gender or gender-related medical requests, although this has been insufficiently studied. In this article, cowritten by expert clinicians and autistic gender-diverse collaborators, an overview of clinical care considerations and the current evidence base is provided.

Abstract
Many transgender people are autistic. Community expressions of the autism transgender intersection abound. Some commentators have questioned the proportional overrepresentation of autism among gender-diverse people, suggesting these individuals may not be truly autistic or truly transgender. However, increasing evidence challenges assertions that deny the authenticity of co-occurring autistic and transgender identities. Specifically, research by authors of this article indicates autistic transgender people show neurophenotypes generally consistent with cisgender autistic people and implicit gender phenotypes consistent with nonautistic transgender people. This article features a dialogue between eight leading experts in the field of intersectional autism and gender diversity, including clinicians, researchers, community advocates, and experts who are themselves autistic transgender. Key topics of discussion included: how research findings on autism and gender diversity inform respectful and supportive responses to autistic transgender people; the benefits and harms of increased societal attention toward the autism transgender intersection; and research and advocacy priorities. The expert panel concluded the following: (1) it is important to respect transgender autistic people's wellness and resilience, while also acknowledging the pathologization and stigmatization they face; (2) autistic gender-diverse people are experts of their own identity and should be involved in all aspects of research and clinical care; (3) research is needed to understand the disparities autistic transgender people face; (4) attempts to restrict autistic transgender people's access to gender care are unsupported by existing research; (5) adult gender care may benefit from incorporating universal design principles and neurodiversity-affirming strategies to reduce barriers to care and improve clinician-client communication in treatment delivery and the informed consent process; (6) cross-cultural and cross-societal research will improve best care practices in diverse contexts; (7) research and advocacy must be inclusive across ethnoracial identities, including in leadership and perspectives represented; and (8) a life span developmental framework is needed for adult research in this field.

Abstract
The common intersection of autism and transgender identities has been described in clinical and community contexts. This study investigates autism-related neurophenotypes among transgender youth. Forty-five transgender youth, evenly balanced across non-autistic, slightly subclinically autistic, and full-criteria autistic subgroupings, completed resting-state functional magnetic resonance imaging to examine functional connectivity. Results confirmed hypothesized default mode network (DMN) hub hyperconnectivity with visual and motor networks in autism, partially replicating previous studies comparing cisgender autistic and non-autistic adolescents. The slightly subclinically autistic group differed from both non-autistic and full-criteria autistic groups in DMN hub connectivity to ventral attention and sensorimotor networks, falling between non-autistic and full-criteria autistic groups. Autism traits showed a similar pattern to autism-related group analytics, and also related to hyperconnectivity between DMN hub and dorsal attention network. Internalizing, gender dysphoria, and gender minority-related stigma did not show connectivity differences. Connectivity differences within DMN followed previously reported patterns by designated sex at birth (i.e. female birth designation showing greater within-DMN connectivity). Overall, findings suggest behavioral diagnostics and autism traits in transgender youth correspond to observable differences in DMN hub connectivity. Further, this study reveals novel neurophenotypic characteristics associated with slightly subthreshold autism, highlighting the importance of research attention to this group.

Abstract
Transidentity and autism frequently co-occur. Previous reviews have focused mainly on frequencies. Here, we conducted a systematic review to condense all the studies and themes on this co-occurrence and to offer a global view. We followed the PRISMA method and selected 77 articles (including 59 clinical studies) in April 2022. We found 5 main themes (sex ratio, theories, sexual orientation, clinical and social consequences, and care implications) in addition to frequencies. Many theories have been proposed to explain the co-occurrence. One posits that social difficulties related to autism would lead to less identification with gender norms and less pressure to conform to these norms, allowing for greater gender diversity in people with autism. Given their difficulties with social interactions and communication, the announcement of one's transidentity to one's social group is often discredited, increasing the risk of suffering and delayed care. Many reports reaffirm the importance of providing specialised care for transgender people with autism. Autism is not a contraindication for gender-affirming treatment. However, some cognitive specificities can affect the planning of care, and transgender people with autism are at high risk of discrimination and harassment. We conclude that there is a need to raise awareness about gender and autism.

Abstract
Background Little research addresses the experiences of autistic people at work, yet employment prospects remain bleak. The extant literature takes a largely remedial perspective and does not focus on harnessing this population's considerable talents. In global organizational practice, several programs purposefully target autistic people for their abilities. However, preliminary evidence suggests that such programs are inadvertently attracting mainly White males, to the exclusion of other demographics. Therefore, stigma surrounding autism at work remains, creating potential compound adverse impacts by marginalizing identities, including gender, race, ethnicity, sexuality, and socioeconomic status. We explored the intersection of autism with other marginalizing identities in the context of work. The research focused on labor force participation for autistic people and, for those in employment, perceptions of exclusion and inclusion. We compared the aforementioned variables by gender identity, racial identity, sexuality, socioeconomic background, and geographic origin. Methods We undertook a global cross-sectional survey, advertised through various social media platforms and promoted directly to relevant organizations. The survey included a range of validated measures as well as demographic information. We analyzed the data with frequencies, cross tabulations, chi-square tests, and non-parametric, group-wise comparisons. Results We found preliminary evidence of reduced rates of employment participation by race and geographic location. Females and non-binary people had lower perceptions of inclusion and belonging at work. The perception of accommodation provision had a strong association with inclusion and belonging; more so than incidental provision of flexibility in environment and scheduling not framed as a specific accommodation. Conclusions The findings highlight the relational aspects of accommodation and a more universal inclusion perspective. We urge practitioners and researchers to monitor employment participation and levels of inclusion/exclusion using intersectional demographic identification. We appeal for cross-cultural collaboration with academic institutions outside the anglosphere to improve our knowledge of global programs and their impact.

Abstract
Evidence indicates a link between autism spectrum disorder (ASD) and gender diversity, yet this intersection remains insufficiently understood. Here, we investigated whether (1) ASD affects gender-related cognition (i.e., mental processes of perceiving and interpreting one's own gender self-concept), (2) autistic people have increased gender dysphoria and recall limited gender-typed behavior from childhood, and (3) transgender individuals have increased ASD-like traits and difficulties in mentalizing. A total of 106 non-autistic cisgender (51 birth-assigned female), 107 autistic cisgender (57 birth-assigned female), 78 non-autistic transgender (41 birth-assigned female), and 56 autistic transgender adults (27 birth-assigned female) participated in the study. The mean age of participants was 31.01 years (range = 18 to 70). Using an explicit as well as an implicit measure, for the first time, we found that ASD affected gender-related cognition only in autistic cisgender people. Sex differences were also observed in this group. Whereas autistic cisgender birth-assigned males showed a stronger implicit gender-group identification than non-autistic cisgender birth-assigned males, autistic cisgender birth-assigned females showed a weaker gender-group identification than non-autistic cisgender birth-assigned females. Furthermore, autistic cisgender people reported significantly more gender dysphoric feelings and recalled significantly less gender-typed behavior from childhood than non-autistic cisgender individuals. No difference was observed between non-autistic and autistic transgender people. We also found that relative to non-autistic cisgender individuals, both non-autistic transgender and autistic transgender people reported significantly more ASD-like traits. However, mentalizing difficulties were observed only in the latter group. This research enhances our understanding of the link between ASD and gender diversity.

Abstract
The Reading the Mind in the Eyes test (RMET) is a widely used measure of theory of mind (ToM). Despite its popularity, there are questions regarding the RMET's psychometric properties. In the current study, we examined the RMET in a representative U.S. sample of 1,181 adults. Key analyses included conducting an exploratory factor analysis on the full sample and examining whether there is a different factor structure in individuals with high versus low scores on the 28-item autism spectrum quotient (AQ-28). We identified overlapping, but distinct, three-factor models for the full sample and the two subgroups. In all cases, each of the three models showed inadequate model fit. We also found other limitations of the RMET, including that nearly a quarter of the RMET items did not meet the criteria for inclusion in the RMET that were established in the original validation study. Due to the RMET's weak psychometric properties and the uncertain validity of individual items, as indicated by our study and previous studies, we conclude that significant caution is warranted when using the RMET as a measure of ToM.

Abstract
While research on the prevalence of co-occurring autism spectrum conditions (ASC) and trans gender modality (TGM) is available, less is known about the underlying mechanism of this association. Insight is needed to improve treatment of trans autistic people. This review provides an overview of theories on the ASC-TGM link and the available evidence for/against them published between January 2016 and October 2020. A systematic search was performed in PubMed, PsycINFO, Web of Science, and Scopus. This resulted in 36 studies, in which 15 theories were identified. Results indicate all theories lack substantial empirical support. Unlikely and promising theories were identified. The most promising theories were those on resistance to social norms and weakened sex differences. Future directions are provided.

Abstract
The suggested overlap between autism spectrum disorder (ASD) and gender dysphoria/incongruence (GD/GI) has been much disputed. This review showed a relationship between ASD traits and GD feelings in the general population and a high prevalence of GD/GI in ASD. Our meta-analyses revealed that the pooled estimate of the prevalence of ASD diagnoses in GD/GI people was 11% (p < .001) and the overall effect size of the difference in ASD traits between GD/GI and control people was significant (g = 0.67, p < .001). Heterogeneity was high in both meta-analyses. We demonstrated that the chances that there is not a link between ASD and GD/GI are negligible, yet the size of it needs further investigation.

Abstract
Gender nonconformity is substantially elevated in the autistic population, but the reasons for this are currently unclear. In a recent study, Kallitsounaki and Williams (Kallitsounaki and Williams, Journal of Autism and Developmental Disorders, 2020; authors 1 and 2 of the current paper) found significant relations between autistic traits and both gender dysphoric feelings and recalled cross-gender behaviour, and between mentalising ability and gender dysphoric feelings. The current study successfully replicated these findings (results were supplemented with Bayesian analyses), in sample of 126 adults. Furthermore, it extended the previous finding of the role of mentalising in the relation between autistic traits and gender dysphoric feelings, by showing that mentalising fully mediated this link. Results provide a potential partial explanation for the increased rate of gender nonconformity in the autistic population.
