Gender Identity in Autism: Sex Differences in Social Affiliation with Gender Groups

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.

A Systematic Review of Gender Dysphoria Measures in Autistic Samples

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.

Inextricably tied: Nonbinary autistic individuals' views on how their gender identity and autism are connected

LAY ABSTRACT

This study explores the experiences and identities of nonbinary autistic people. The relationship between autistic and nonbinary identities has not been researched in detail. Few studies focus specifically on nonbinary autistic adults. We interviewed 44 nonbinary individuals for this study. Participants had thought-out opinions on gender identity and emphasized identifying with fluidity rather than traditional gender roles. Participants discussed the connection of their autistic and nonbinary identities and how it affected how people saw them and how they saw themselves. We have recommendations for programming, policy, and research from these findings.

Research methods at the intersection of gender diversity and autism: A scoping review

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.

Development and Initial Validation of the Russian Version of the RAADS-14: A Self-Report Questionnaire to Assess Autistic Traits

Autism is a relatively common neurodevelopmental condition that affects social communication and behavior, affecting the overall quality of life. The prevalence of autism is constantly increasing, but timely diagnosis allows for effective treatment. The aim of our research was to construct a Russian version of the RAADS-14, a brief self-report questionnaire originally designed for autism screening, and to perform its initial validation to provide a reference point in developing autism self-assessment tools for the Russian-speaking population. Psychometric properties of the RAADS-14 Rus were evaluated on a sample of 1724 participants, including a general sample of non-psychiatric young adults (n = 794) and adults with clinically established ASD (n = 49); a brief Russian inventory assessing Big Five personality traits (FFQ) was administered to a part of the sample (n = 364) to provide the first assessment of criterion validity. Confirmatory factor analysis of the RAADS-14 Rus confirmed the factor structure of the original Swedish version yielding acceptable fit indices. The discriminating properties were substantially worse than in the original study. The correlations between the RAADS-14 Rus domain scores and the Big Five factors were similar to previously obtained findings. Overall, the results suggest that the RAADS-14 Rus can be used as a screening tool for ASD in adults with proper caution and considering its discriminating properties.

EEG functional connectivity in infants at elevated familial likelihood for autism spectrum disorder

BACKGROUND

Many studies have reported that autism spectrum disorder (ASD) is associated with atypical structural and functional connectivity. However, we know relatively little about the development of these differences in infancy.

METHODS

We used a high-density electroencephalogram (EEG) dataset pooled from two independent infant sibling cohorts, to characterize such neurodevelopmental deviations during the first years of life. EEG was recorded at 6 and 12 months of age in infants at typical (N = 92) or elevated likelihood for ASD (N = 90), determined by the presence of an older sibling with ASD. We computed the functional connectivity between cortical sources of EEG during video watching using the corrected imaginary part of phase-locking values.

RESULTS

Our main analysis found no significant association between functional connectivity and ASD, showing only significant effects for age, sex, age-sex interaction, and site. Given these null results, we performed an exploratory analysis and observed, at 12 months, a negative correlation between functional connectivity and ADOS calibrated severity scores for restrictive and repetitive behaviors (RRB).

LIMITATIONS

The small sample of ASD participants inherent to sibling studies limits diagnostic group comparisons. Also, results from our secondary exploratory analysis should be considered only as potential relationships to further explore, given their increased vulnerability to false positives.

CONCLUSIONS

These results are inconclusive concerning an association between EEG functional connectivity and ASD in infancy. Exploratory analyses provided preliminary support for a relationship between RRB and functional connectivity specifically, but these preliminary observations need corroboration on larger samples.

The Gender Self-Report: A multidimensional gender characterization tool for gender-diverse and cisgender youth and adults

Gender identity is a core component of human experience, critical to account for in broad health, development, psychosocial research, and clinical practice. Yet, the psychometric characterization of gender has been impeded due to challenges in modeling the myriad gender self-descriptors, statistical power limitations related to multigroup analyses, and equity-related concerns regarding the accessibility of complex gender terminology. Therefore, this initiative employed an iterative multi-community-driven process to develop the Gender Self-Report (GSR), a multidimensional gender characterization tool, accessible to youth and adults, nonautistic and autistic people, and gender-diverse and cisgender individuals. In Study 1, the GSR was administered to 1,654 individuals, sampled through seven diversified recruitments to be representative across age (10-77 years), gender and sexuality diversity (∼33% each gender diverse, cisgender sexual minority, cisgender heterosexual), and autism status (> 33% autistic). A random half-split subsample was subjected to exploratory factor analytics, followed by confirmatory analytics in the full sample. Two stable factors emerged: Nonbinary Gender Diversity and Female-Male Continuum (FMC). FMC was transformed to Binary Gender Diversity based on designated sex at birth to reduce collinearity with designated sex at birth. Differential item functioning by age and autism status was employed to reduce item-response bias. Factors were internally reliable. Study 2 demonstrated the construct, convergent, and ecological validity of GSR factors. Of the 30 hypothesized validation comparisons, 26 were confirmed. The GSR provides a community-developed gender advocacy tool with 30 self-report items that avoid complex gender-related "insider" language and characterize diverse populations across continuous multidimensional binary and nonbinary gender traits.

Disclosing an autism diagnosis: A social identity approach

Autistic people face a difficult dilemma around whether or not to disclose their diagnosis because autistic people are a stigmatized social group. The central aim of this study was to examine if a social identity approach could be useful in understanding the factors that predict the likelihood of autistic adults disclosing their autism diagnosis in social settings, in the workplace, in educational settings and in the family. The social identity approach predicts that autistic people may cope with this dilemma by using an individualistic strategy to distance themselves from their autistic social identity. Alternatively, they may embrace their autistic social identity and use a collective strategy to resist stigma and advocate for autistic people. We present a survey based cross-sectional study (n = 175) with autistic adults living in Ireland. Participants completed a series of measures; autism social identification, stigma consciousness, and individualistic and collective strategy use to assess disclosing in the four settings. The overall models in each of the four regressions were significant. Autism social identification positively predicted disclosure in social, workplace and educational settings, while stigma consciousness negatively predicted disclosure in the family and in the workplace. Interestingly, over and above these predictors individualistic strategy use negatively predicted disclosure in each of the four settings, while collective strategy use positively predicted disclosure in social, educational and family settings. Our novel social identity approach was useful for explaining autistic adults' strategies to cope with the complex disclosure dilemma. Strengths, limitations, and directions for future research are discussed.

Applications of identity-based theories to understand the impact of stigma and camouflaging on mental health outcomes for autistic people

Autistic people have long been conceptualized from a deficit-based model of disability, but recent self-advocates and scholars have asserted the importance of recognizing autism as both a disability and an important part of a person's social identity. The autistic identity is subject to specific stigma and stressors beyond everyday discrimination and prejudice, which can have many downstream implications on mental health and well-being. Prior research on camouflaging has explained both quantitatively and qualitatively how autistic people conform to norms and mask their autistic traits to better fit in with non-autistic societal standards. Given this paradigm shift in understanding autistic peoples' lived experiences, researchers must also begin to reshape the theories guiding their work in order to improve diagnosis, intervention, and supports. This review examines the extant research on identity-related stigma and camouflaging and their subsequent impacts on mental health outcomes in autism. A model is proposed integrating identity-based theories-specifically the social model of disability, social identity theory, and minority stress model-to explain relationships across research areas and better explain the experiences of autistic people. We discuss how identity-based theories can be applied in autism research to better understand the impacts of stigma and camouflaging on autistic peoples' lived experiences and reduce disparities in their mental health outcomes.

Shining a Light on a Hidden Population: Social Functioning and Mental Health in Women Reporting Autistic Traits But Lacking Diagnosis

Female Phenotype Theory (FPT) suggests that autistic women often present with less obvious social impairments than autistic men. We examined the possibility of an exaggerated female phenotype among undiagnosed but probably autistic women. In two nationwide online surveys, we compared self-reported social functioning and mental health between diagnosed autistic women and women without diagnosis who scored ≥ 32 on the Autism Quotient. Compared to diagnosed autistic women, probably autistic women had higher empathy and general social functioning, and were more likely to have received a diagnosis of Borderline Personality Disorder. Autistic women had typically received more mental health diagnoses prior to their ASC diagnosis than autistic men. These findings shed light on the history of misdiagnosis experienced by many autistic women.

The autism spectrum among transgender youth: default mode functional connectivity

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.

Parent reported barriers and facilitators to support services for autistic children in Aotearoa New Zealand

LAY ABSTRACT

Parents might have problems in getting support services for their autistic child due to certain barriers. However, there might also be things that can ease or facilitate parents' access to support services. In this study, New Zealand parents were asked about their experiences in getting support services for their autistic child. We also looked at differences in reported barriers and facilitators based on several demographic factors with a focus on family level of financial resourcing. A total of 173 parents completed a survey. The results suggested that parents experienced several barriers, particularly related to service pathways. Facilitators were also experienced, predominantly related to providers. Financial resourcing predicted the number of parent-reported barriers. Both lower level of family financial resourcing and having a non-binary child predicted parents' rating of the extent of barriers. Child age and level of speech were predictors for reports of experiencing a higher number of facilitators, with parents of younger children or of non-speaking autistic children reporting a greater number of facilitators. We discuss how these results may be useful to support service delivery and identify areas for future research.

Transidentities and autism spectrum disorder: A systematic review

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.

Greater gender diversity among autistic children by self-report and parent-report

LAY ABSTRACT

Gender diversity broadly refers to the way in which an individual experiences (expressions and/or identities) their gender distinctly to that which would be expected based upon social norms for their gender assigned at birth. Recent research has shown a higher representation of gender diversity among autistic youth. Previous research in this area has relied on parent-report based on a single question from the Child Behavior Checklist Item-110, asking whether their child "Wishes to be the opposite sex." The Gender Diversity Screening Questionnaire Self-Report and Parent-Report were used to assess the experience of gender diversity in 244 children (140 autism spectrum disorder and 104 typically developing) between 10 and 13 years. The Item-110 was also collected. Results showed that autistic children endorsed much higher rates of Binary Gender Diversity (less identification with their designated sex and more with the other binary sex) and Nonbinary Gender Diversity (identification as neither male nor female) than typically developing children. Similarly, parents of autistic children reported significantly more gender-body incongruence experienced by their child than parents of typically developing children. Specifically, parents of autistic females-assigned-at-birth reported significantly more gender-body incongruence than autistic males-assigned-at-birth. Parent- and self-report measures were largely related. Moreover, statistical comparisons between and within the groups revealed associations between gender profiles and symptoms of anxiety, depression, and suicidality. Results extend previous reports showing increased rates of gender diversity in autistic children, now based on both self-report and parent-report, and highlight the need to better understand and support the unique and complex needs of autistic children who experience gender diversity.

Sex and Sexuality in Autism Spectrum Disorders: A Scoping Review on a Neglected but Fundamental Issue

ASD consists of a set of permanent neurodevelopmental conditions, which are studded with social and communication differences, limited interests, and repetitive behaviors. Individuals with ASD have difficulty reading eye gestures and expressions, and may also have stereotyped or repetitive language, excessive adherence to routines, fixed interests, and rigid thinking. However, sexuality in adolescents and young adults with ASD is still a poorly studied and neglected issue. This review aims to evaluate sexual function and behavior in individuals with ASD to foster a greater understanding of this important, although often overlooked, issue. This review was conducted by searching peer-reviewed articles published between 01 June 2000 and 31 May 2022 using the following databases: PubMed, Embase, Cochrane Database, and Web of Science. A comprehensive search was conducted using the terms: "Autism" OR "ASD" AND "Sexuality" OR "Romantic relation" OR "sexual behavior" AND/OR "sexual awareness". After an accurate revision of 214 full manuscripts, 11 articles satisfied the inclusion/exclusion criteria. This review found that, although individuals with ASD may have sexual functioning, their sexuality is characterized by higher prevalence rates of gender dysphoria and inappropriate sexual behavior. Furthermore, sexual awareness is reduced in this patient population, and the prevalence of other variants of sexual orientation (i.e., homosexuality, asexuality, bisexuality, etc.) is higher in adolescents with ASD than in non-autistic peers. Sexual health and education should be included in the care path of patients with ASD in order to improve their quality of life and avoid/reduce inappropriate and risky behaviors.

Implicit and Explicit Gender-Related Cognition, Gender Dysphoria, Autistic-Like Traits, and Mentalizing: Differences Between Autistic and Non-Autistic Cisgender and Transgender Adults

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.

L’identité de genre, entre faits naturels et faits construits, une approche intégrative et développementale

À partir des années 1950, l’identité de genre, en ce qu’elle définit la conviction de l’individu d’appartenir à un genre ou à un autre, devient un objet de recherche médicale et scientifique. Partant des premiers travaux de John Money et de Robert Stoller, qui posent la possibilité d’une dimension polyfactorielle de la construction de l’identité de genre, les recherches les plus récentes portant sur les facteurs génétiques, neuroanatomiques, socio-cognitifs et psychodynamiques, réactualisent l’intérêt de pouvoir envisager un modèle polyfactoriel. Le paradigme clinique des variations du développement génital et des troubles du spectre de l’autisme entrouvre des hypothèses quant à l’articulation possible de ces facteurs de différentes natures. Pour appuyer tant ces éléments historiques que les données issues de la recherche actuelle, nous développerons en quoi les pratiques médicales actuelles vis-à-vis du genre s’inscrivent, sur le plan déontologique, dans une approche nécessairement individualisée soutenant un modèle polyfactoriel développemental.

Is the dolphin a fish? ERP evidence for the impact of typicality during early visual processing in ultra-rapid semantic categorization in autism spectrum disorder

BACKGROUND

Neurotypical individuals categorize items even during ultra-rapid presentations (20 ms; see Thorpe et al. Nature 381: 520, 1996). In cognitively able autistic adults, these semantic categorization processes may be impaired and/or may require additional time, specifically for the categorization of atypical compared to typical items. Here, we investigated how typicality structures influence ultra-rapid categorization in cognitively able autistic and neurotypical male adults.

METHODS

Images representing typical or atypical exemplars of two different categories (food/animals) were presented for 23.5 vs. 82.3 ms (short/long). We analyzed detection rates, reaction times, and the event-related potential components dN150, N1, P2, N2, and P3 for each group.

RESULTS

Behavioral results suggest slower and less correct responses to atypical compared to typical images. This typicality effect was larger for the category with less distinct boundaries (food) and observed in both groups. However, electrophysiological data indicate a different time course of typicality effects, suggesting that neurotypical adults categorize atypical images based on simple features (P2), whereas cognitively able autistic adults categorize later, based on arbitrary features of atypical images (P3).

CONCLUSIONS

We found evidence that all three factors under investigation - category, typicality, and presentation time - modulated specific aspects of semantic categorization. Additionally, we observed a qualitatively different pattern in the autistic adults, which suggests that they relied on different cognitive processes to complete the task.

Theories on the Link Between Autism Spectrum Conditions and Trans Gender Modality: a Systematic Review

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.

Rural-Urban Differences in Age at Autism Diagnosis: A Multiple Model Analysis

Objective: Early recognition of autism is important, but diagnosis age varies among children. Recent studies have aimed to identify factors affecting age of diagnosis and several studies have attempted to explore geographic variation in age at diagnosis of autism. However, there is a lack of research examining geographic variations with multiple models to find whether geographic differences can be explained by risk factors such as socioeconomic status and differences in child characteristics. This study aimed to address this gap of knowledge by comparing age at diagnosis of autism between the group of people living in the center of the province and the group of people living in the rest of the province, considering potential medical and socioeconomic confounders. Method : The study population consisted of 50 autistic children born in East Azerbaijan Province between 2004 and 2016. Initially, univariate testing by ANOVA was performed to identify family and individual factors contributing to differences in age at autism diagnosis. Following this, the association between living in the center of the province and age at diagnosis in univariate and multivariate analyses was examined. Results: Results from the initial univariate analysis indicate a significant association between living in the center of province and early diagnosis. However, inclusion of possible confounders in multiple model illustrates that these geographical disparities in age at diagnosis can be explained by differences in socioeconomic and medical status. Conclusion: Although geographic variation in age at diagnosis of autism was observed, analyses show that differences in individual and family-level factors may contribute to geographic differences. In this study, most of the observed variation was accounted for by family-level factors rather than geographic policies. Findings prove that multiple strategies are required to identify targeted interventions and strategies.

Is It Autism? A Critical Commentary on the Co-Occurrence of Gender Dysphoria and Autism Spectrum Disorder

An increasing amount of literature revealed a link between GD and ASD. Both GD and ASD are complex and heterogeneous conditions characterized by a large variety of presentations. Studies have reported that individuals with GD tend to have higher prevalence rates of autistic traits in comparison to the general population. The purpose of this commentary is to provide, through the description of a clinical case, our reading and a possible interpretation of the correlation of these two conditions in light of the several methodological limitations found in literature. We hypothesize that the traits often classified as autistic could be more accurately related to the distress and discomfort evoked by GD. The autistic traits of individuals with GD as forms of psychological defenses and coping mechanisms aimed at dealing with socio-relational and identity problems are discussed.

Autism Spectrum Disorder and Gender Dysphoria/Incongruence. A systematic Literature Review and Meta-Analysis

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.

Autistic Traits, Empathizing-Systemizing, and Gender Diversity

Previous research indicates a link between autism and transgender and gender-diverse identities, though the association is not yet fully understood. The current study examined autistic traits (Autism Spectrum Quotient [AQ]), empathizing (Empathizing Quotient-Short [EQ-S]), and systemizing (Systemizing Quotient-Short [SQ-S]) in a sample of 89 adults and aimed to test whether gender-diverse individuals exhibit cognitive profiles consistent with predictions derived from the Extreme Male Brain (EMB) theory. As most research has considered only cisgender people, we recruited a more diverse sample by contacting > 200 UK LGBTQ+ organizations and posting on social media. A range of non-cisgender identities (e.g., transgender male, transgender female, non-binary, genderqueer, transmasculine) and non-heterosexual orientations (e.g., bisexual) were represented, and participants were categorized into one of four groups: (1) assigned female at birth but does not identify as female (transgender AFAB) (n = 32), (2) cisgender female (n = 21), (3) assigned male at birth but does not identify as male (transgender AMAB) (n = 18), and (4) cisgender male (n = 18). After controlling for age and autism diagnostic status, transgender AFAB participants had marginally higher AQ scores, and significantly higher SQ-S and systemizing-relative-to-empathizing (D) scores, compared with the cisgender female group. No such differences were detected between the transgender AMAB and cisgender male groups. Our findings are broadly in line with predictions derived from the EMB theory, though as no transgender AFAB participants reported being heterosexual, it was not possible to determine whether these effects relate specifically to gender identity, to sexual orientation, or to both.

Social Responsiveness and Psychosocial Functioning in Adults with Prader-Willi Syndrome

Although various studies have investigated symptoms of autism spectrum disorder (ASD) in Prader−Willi syndrome (PWS), little is known about the consequences of these symptoms, especially in psychosocial function. We aimed to explore ASD symptoms in adults with PWS with special attention to psychosocial functionality. This cross-sectional study included 26 adults (15 women) with PWS who attended a reference unit for rare diseases. Participants’ primary caregivers completed the Social Responsiveness Scale (SRS), and clinicians assessed multidimensional functioning with the Personal and Social Performance Scale (PSP). Impaired social responsiveness was identified in 20 (76.9%) participants, and manifest to marked difficulties in social functioning were identified in 13 (50%). Participants with impaired social responsiveness (SRS ≥ 60) had significantly worse scores in functionality measured with the PSP (U = 12.5; p = 0.009) and with three of the four PSP main areas. Moreover, scores for the Social Cognition domain of the SRS correlated positively with the Socially useful activities (p < 0.05) and Personal and social relationships (p < 0.01) main areas of the PSP. These results suggest that difficulties in social skills should be assessed in all psychosocial evaluations of patients with PWS.

Challenging Empathic Deficit Models of Autism Through Responses to Serious Literature

Dominant theoretical models of autism and resultant research enquiries have long centered upon an assumed autism-specific empathy deficit. Associated empirical research has largely relied upon cognitive tests that lack ecological validity and associate empathic skill with heuristic-based judgments from limited snapshots of social information. This artificial separation of thought and feeling fails to replicate the complexity of real-world empathy, and places socially tentative individuals at a relative disadvantage. The present study aimed to qualitatively explore how serious literary fiction, through its ability to simulate real-world empathic response, could therefore enable more ecologically valid insights into the comparative empathic experiences of autistic and non-autistic individuals. Eight autistic and seven non-autistic participants read Of Mice and Men for six days while completing a semi-structured reflective diary. On finishing the book, participants were asked to engage in three creative writing tasks that encouraged reflective thinking across the novel. Thematic and literary analysis of the diary reflections and writing tasks revealed three main themes (1) Distance from the Novel; (2) Mobility of Response; (3) Re-Creating Literature. Findings demonstrated the usefulness of serious literature as a research tool for comparing the empathic experiences of autistic and non-autistic individuals. Specifically, autistic individuals often showed enhanced socio-empathic understandings of the literature with no empathy deficits when compared to non-autistic participants.

The Diagnosis and Management of Autism Spectrum Disorder (ASD) in Adult Females in the Presence or Absence of an Intellectual Disability

We review the reasons for the greater male predominance in the diagnosis of autism spectrum disorder in the non-intellectual disabled population and compare it to autism diagnosed in intellectually disabled individuals. Accurate and timely diagnosis is important, as it reduces health inequalities. Females often present later for the diagnosis. The differences are in core features, such as in social reciprocal interaction through 'camouflaging' and restricted repetitive behaviours, that are less noticeable in females and are potentially explained by the biological differences (female protective effect theory) and/or differences in presentation between the two sexes (female autism phenotype theory). Females more often present with internalising co-occurring conditions than males. We review these theories, highlighting the key differences and the impact of a diagnosis on females. We review methods to potentially improve diagnosis in females along with current and future management strategies.

Flexibility in autism during unpredictable shifts of socio-emotional stimuli: Investigation of group and sex differences

LAY ABSTRACT

Flexibility difficulties in autism might be particularly common in complex situations, when shifts (i.e. the switch of attentional resources or strategy according to the situation) are unpredictable, implicit (i.e. not guided by explicit rules) and the stimuli are complex. We analyzed the data of 101 autistic and 145 non-autistic adults, without intellectual deficiency, on two flexibility tasks performed online. The first task involved unpredictable and non-explicit shifts of complex socio-emotional stimuli, whereas the second task involved predictable and explicit shifts of character stimuli. Considering the discrepancies between laboratory results and the real-life flexibility-related challenges faced by autistic individuals, we need to determine which factor could be of particular importance in flexibility difficulties. We point out that the switch cost (i.e. the difference between shift and non-shift condition) was larger for autistic than for non-autistic participants on the complex flexibility task with unpredictable and non-explicit shifts of socio-emotional stimuli, whereas this was not the case when shifts were predictable, explicit and involved less complex stimuli. We also highlight sex differences, suggesting that autistic females have better social skills than autistic males and that they also have a specific cognitive profile, which could contribute to social camouflaging. The findings of this work help us understand which factors could influence flexibility difficulties in autism and are important for designing future studies. They also add to the literature on sex differences in autism which underpin better social skills, executive function, and camouflaging in autistic females.

Sex/gender differences in the human autistic brains: A systematic review of 20 years of neuroimaging research

Our current understanding of autism is largely based on clinical experiences and research involving male individuals given the male-predominance in prevalence and the under-inclusion of female individuals due to small samples, co-occurring conditions, or simply being missed for diagnosis. There is a significantly biased 'male lens' in this field with autistic females insufficiently understood. We therefore conducted a systematic review to examine how sex and gender modulate brain structure and function in autistic individuals. Findings from the past 20 years are yet to converge on specific brain regions/networks with consistent sex/gender-modulating effects. Despite at least three well-powered studies identifying specific patterns of significant sex/gender-modulation of autism-control differences, many other studies are likely underpowered, suggesting a critical need for future investigation into sex/gender-based heterogeneity with better-powered designs. Future research should also formally investigate the effects of gender, beyond biological sex, which is mostly absent in the current literature. Understanding the roles of sex and gender in the development of autism is an imperative step to extend beyond the 'male lens' in this field.

Interpersonal Trauma and Posttraumatic Stress in Autistic Adults

Background

Many autistic adults report interpersonal traumas (IPTs) such as physical or sexual assault, which are often associated with posttraumatic stress and dissociation. Factors such as gender might make autistic individuals particularly vulnerable to experiencing IPT and negative posttraumatic symptoms.

Methods

In this study, 687 self-identified autistic adults completed an online survey on their traumatic experiences and mental health symptoms.

Results

Seventy-two percent of participants reported experiencing sexual assault, other unwanted or uncomfortable sexual experiences, or physical assault. Forty-four percent of participants met the criteria for posttraumatic stress disorder (PTSD), including 50% of those who had experienced IPT and 28% of those who had not (odds ratio = 2.50; 95% confidence interval 1.74-3.60). IPT was also significantly associated with higher levels of psychoform (p < 0.001) and somatoform (p < 0.001) dissociation. Autistic cisgender women and gender minorities experienced a significantly higher number of traumas (p = 0.004) and were significantly more likely than cisgender men to experience sexual IPT (p < 0.001) and meet the criteria for PTSD (p < 0.001). There were no significant differences between autistic individuals with and without a professional autism spectrum disorder (ASD) diagnosis.

Conclusions

IPT is associated with potentially severe mental health outcomes for autistic adults. Autistic women and gender minorities may be particularly vulnerable to sexual IPT and adverse outcomes. Increased screening for a history of IPT and posttraumatic symptoms is recommended for all autistic adults regardless of ASD diagnosis status.

Lay summary

Why was this study done?: Many autistic people experience interpersonal traumas (IPTs) such as sexual or physical assault. These can lead to mental health challenges such as posttraumatic stress disorder (PTSD) or dissociation (a disconnection between individuals and aspects of their perceptions or sense of self). We wanted to better understand what might make autistic adults more likely to experience trauma and how it affects them.What was the purpose of this study?: The purpose was to understand what might make autistic people more at risk of experiencing IPT and PTSD. We also wanted to know if IPT is associated with a higher risk of PTSD or dissociation.What did the researchers do?: Six hundred eighty-seven autistic adults filled out an online survey about their traumatic experiences, PTSD symptoms, and dissociation symptoms. We analyzed their responses to see how often participants reported experiencing different types of trauma and whether they met the criteria for PTSD and clinical dissociation. We then compared trauma experiences and PTSD rates across genders and those with and without a professional autism spectrum disorder (ASD) diagnosis and compared PTSD rates and dissociation rates across participants who had versus had not experienced IPT.What were the results of the study?: Seventy-two percent of autistic adults in this study reported having experienced sexual assault, another unwanted sexual experience, or physical assault. Almost half (44%) met the criteria for PTSD. Most participants (93%) also reported high levels of mind-based dissociation, and 32% reported high levels of body-based dissociation (dissociation that causes negative emotions to be experienced as physical problems such as headaches or trouble moving). Participants who had experienced IPT were almost twice as likely to meet the criteria for PTSD and scored higher on both measures of dissociation. Cisgender women and gender minorities were more likely to experience IPT and meet the criteria for PTSD than cisgender men. Participants with and without a professional ASD diagnosis did not differ.What do these findings add to what was already known?: Most previous research on trauma and PTSD for autistic people was done on children and did not look at IPT specifically or compare people based on their gender or ASD diagnosis. As far as we know, this is the first study on posttraumatic dissociation in autistic adults.What are potential weaknesses in the study?: The findings of this study may not apply to autistic adults as a whole. People who could have participated may not have been interested in the topic, may not have seen study advertisements and so been unaware of the study, or may not have had the time or energy to participate. Findings might have been different if different groups of autistic people participated more.How will these findings help autistic adults now or in the future?: If professionals who help autistic people do not talk to them about trauma, traumatized autistic adults may not get the right support. This study could encourage professionals to screen more autistic people, especially women and gender minorities, for trauma.

An analysis of the reading habits of autistic adults compared to neurotypical adults and implications for future interventions

BACKGROUND

While research has consistently highlighted the usefulness of narrative texts for social development, this has not been fully explored with autistic adults. It has long been assumed that autistic individuals lack the social understanding to contemplate fiction, preferring non-fiction. This study aimed to explore the self-reported reading habits of autistic adults compared to neurotypical adults, accounting for higher education demands.

METHODS

A qualitative design was used, with 43 participants (22 autistic; 21 neurotypical) completing a reading habits questionnaire and subsequent semi-structured interview.

RESULTS

Neurotypical participants tended to prefer fiction, with autistic participants showing no preference between fiction and non-fiction. Four themes were identified from interview data (1) reading material choices; (2) text investment; (3) in-text social understanding; and (4) reading as a social learning device. Both groups reported evidence of empathising, perspective-taking and social understanding while reading. The autistic group additionally reported social learning outcomes from reading.

DISCUSSION

Findings contradict prior assumptions that autistic individuals lack the social understanding required by fiction. Instead, findings show that social benefits of narrative texts extend to autistic readers, providing important social learning experiences.

Sexual Knowledge, Desires, and Experience of Adolescents and Young Adults With an Autism Spectrum Disorder: An Exploratory Study

Although most persons with an Autism Spectrum Disorder (ASD) wish to have romantic and/or sexual relationships, little is known about self-report sexuality of adolescents/young adults with ASD. In this exploratory study, 172 male and female adolescents/young adults (68 with ASD and 104 without ASD) completed an online version of the Sexual Behavior Scale-Third edition. Although many more similarities than differences were observed between the groups for views and desires about romantic relationships (e.g., wishing to have a girlfriend/boyfriend), fewer participants with ASD (mostly boys) had experience with a variety of sexual/dyadic behaviors, and approximately half of girls with ASD reported negative sexual experiences. Significantly higher rates of participants with ASD felt their knowledge about sexuality was limited and found it difficult to understand sexual education compared with typically developing (TD) participants. Significantly lower rates of participants with ASD reported that they identify to their assigned gender compared with TD participants. Multiple regressions revealed that being older at first diagnosis and possessing better knowledge about sexuality were significant predictors of both positive and negative sexual experience. This study explores strengths and challenges related with the sexual health of adolescents/young adults with ASD and implications for clinical and educational practice are discussed.

Social identities and mental well-being in autistic adults

Social identities relate to psychological perceptions of group memberships and form part of the self-concept. Socially identifying with groups has previously been found to associate with better mental well-being outcomes. This study first examined the factor structure and the reliability of measuring social identification in autistic adults. Confirmatory factor analysis showed that a factor structure was replicated in this sample for social identification with other autistic people, but not the family. Second, the study assessed the level to which autistic adults socially identified with different groups, the total number of social identities and whether these were associated with their mental well-being. Autistic adults reported feelings of social identification with many kinds of groups, some with multiple groups, whereas others did not socially identify with any group. Stronger feelings of social identification towards other autistic people and towards one’s family, and with more groups overall, were associated with less severe self-reported depression symptoms and more facets of positive mental health. These findings indicate the importance of facilitating autistic people’s engagement with social groups.

Inclusive Practices for Neurodevelopmental Research

Purpose of Review

Inclusive research practice is both a moral obligation and a practical imperative. Here we review its relevance to the study of neurodevelopmental diversity in particular, briefly describing a range of inclusive research models and justifying their use. The review itself is inclusively co-authored with three autistic collaborators and community leaders who all have extensive experience of research involvement.

Recent Findings

Drawing on theoretical arguments and specific exemplar projects, we describe six key considerations in the delivery of inclusive research. These are the following: taking the first steps towards inclusive practice; setting expectations; community-specific inclusion measures; inclusion and intersectionality; the role of empowerment; and knowledge exchange for inclusion. Together, these sections provide an illustrated guide to the principles and process of inclusive research.

Summary

Inclusive research practice is both beneficial to and a requirement of excellence in neurodevelopmental research. We call for greater engagement in this participatory research agenda from grant-awarding bodies to facilitate not just inclusive but also emancipatory research.

Exploring Three Core Psychological Elements When Treating Adolescents on the Autism Spectrum: Self-Awareness, Gender Identity, and Sexuality

For those growing up on the autism spectrum, adolescence is associated with unique challenges. This narrative review explores three core psychological elements for clinicians to consider when treating adolescents on the autism spectrum: self-awareness, gender identity, and sexuality. Developmental tasks of adolescence include adaptation to a maturing mind and body, increased expectations for independence, and the ability to establish satisfying interpersonal relationships. What are welcome opportunities for non-autistic peers can become nearly insurmountable hurdles for autistic teens, which, in turn, could lead to crisis, particularly if skills needed for success in managing these tasks have not yet been acquired.

How children with autism spectrum disorder perceive themselves: A narrative research

AIM

The purpose of this article is, through a dialog between the child and the author, to clarify how children with autism spectrum disorder (ASD) perceive themselves.

METHODS

The qualitative study's participants were nine children with ASD. Their ages were 8-18 years. Data were collected through two sessions of dialog between the child and the author. Data were analyzed through a qualitative inductive approach based on the perspectives of narrative analysis.

RESULTS

There were eight categories of how the children perceive themselves. The children talked about themselves as follows. The children with ASD wished to share feelings with others, sensitively read between the lines, and talked about the belief to cherish their friends. They were able to anticipate that repetitive behavior or interest in one thing would end someday. And they then made an effort to deal with problematic matters in social life.

CONCLUSION

This article proposes to understand the experience of "increasing alienation" in children with ASD. As a type of support to understand the child, this article proposed a dialog that elicits communication arrangements, specifically a dialog that focuses on forming a profound relationship of being able to share and communicate with each other.

Benefits and Risks: A Systematic Review of Information and Communication Technology Use by Autistic People

Background

Communication via the internet is a regular feature of everyday interactions for most people, including autistic people. Researchers have investigated how autistic people use information and communication technology (ICT) since the early 2000s. However, no systematic review has been conducted to summarize findings.

Objective

This study aims to review existing evidence presented by studies about how autistic people use ICT to communicate and provide a framework for understanding contributions, gaps, and opportunities for this literature.

Methods

Guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses(PRISMA) statement, we conducted a comprehensive review across five databases, searching for studies investigating how autistic youth and adults use ICT to communicate. Authors reviewed the articles for inclusion and assessed methodological quality.

Results

Thirty-two studies met the eligibility criteria, including 19 quantitative studies, 12 qualitative studies, and 1 mixed methods study, with data from 3026 autistic youth (n = 9 studies) and adults (n = 23 studies). Ratings suggest that the evidence base is emergent. Underrepresented groups in the sample included autistic women, transgendered autistic people, non-White autistic people, low income autistic people, and minimally speaking and/or autistic adults with co-occurring intellectual disability. Three main themes emerged, including variation in ICT communication use among autistic youth and adults, benefits and drawbacks experienced during ICT communication use, and the engagement of autistic youth and adults in the online autism community.

Conclusions

Further exploration of the positive social capital that autistic people gain participating in online autism communities would allow for the development of strengths-based interventions. Additional research on how autistic people navigate sexuality and ICTs is needed to identify mechanisms for reducing vulnerability online. Additional scholarship about underrepresented groups is needed to investigate and confirm findings regarding ICT communication use for gender, racial, and socioeconomic minority groups.

Lay summary

What was the purpose of this study?: People use the internet to communicate (talk and connect) with one another. Some research has found that autistic people may prefer to communicate using the internet instead of in person. Over the past 20 years, there has been research about how autistic people use the internet. To understand what research has discovered so far, we collected published research about how autistic youth and adults use the internet to communicate.What did the researchers do?: We used scientific best practices as described in the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to collect research about how autistic people us the internet to communicate. We included research that uses words (qualitative research) and numbers (quantitative research). First, we searched several places that list research studies to find research on autistic people and the internet. Then, we removed research that did not fit what we were looking for (our criteria). Finally, we then read the full articles, collected their most important findings, and looked for patterns.What do these findings add to what is already known?: Thirty-two studies met our criteria, including 19 studies that used closed-ended survey questions that tested relationships between variables, 12 studies that used open-ended interviews and looked for patterns and connections among participants, and 1 mixed methods study. In total, 3026 autistic youth of ages 10-17 years (number of participants = 9 studies) and adults (number of participants = 23 studies) participated in these 32 studies. We rated each of the 32 studies for quality and learned that the evidence base is preliminary, meaning that more rigorous high-quality studies are needed before we can be confident in the findings. We found three main themes: (1) differences in the ways that autistic youth and adults used the internet to communicate, (2) benefits and drawbacks experienced when using the internet to communicate, and (3) the engagement of autistic youth and adults in the online autism community. Some of the benefits of social media for autistic people include more control over how they talk and engage with others online and a greater sense of calm during interactions. However, findings suggest some drawbacks for autistic people, including continued feelings of loneliness and the desire for in-person friendships. Social media provides opportunities for autistic people to find others on the autism spectrum and form a stronger identity as part of the autism community. The study also showed that there is little research about autistic women, autistic transgender people, autistic racial/ethnic minorities, or autistic people from lower socioeconomic status (SES) groups.What are potential weaknesses of this study?: We only included research in scientific articles, and there may be useful information on this topic in books, student research, or online.How will these findings help young adults on the autism spectrum now or in the future?: This study can help identify gaps and opportunities for new research, support the importance of online autistic communities, and suggest possible training opportunities about how to support autistic people when they use the internet for communication.

A Conceptual Analysis of Autistic Masking: Understanding the Narrative of Stigma and the Illusion of Choice

Autistic masking is an emerging research area that focuses on understanding the conscious or unconscious suppression of natural autistic responses and adoption of alternatives across a range of domains. It is suggested that masking may relate to negative outcomes for autistic people, including late/missed diagnosis, mental health issues, burnout, and suicidality. This makes it essential to understand what masking is, and why it occurs. In this conceptual analysis, we suggest that masking is an unsurprising response to the deficit narrative and accompanying stigma that has developed around autism. We outline how classical social theory (i.e., social identity theory) can help us to understand how and why people mask by situating masking in the social context in which it develops. We draw upon the literature on stigma and marginalization to examine how masking might intersect with different aspects of identity (e.g., gender). We argue that although masking might contribute toward disparities in diagnosis, it is important that we do not impose gender norms and stereotypes by associating masking with a "female autism phenotype." Finally we provide recommendations for future research, stressing the need for increased understanding of the different ways that autism may present in different people (e.g., internalizing and externalizing) and intersectionality. We suggest that masking is examined through a sociodevelopmental lens, taking into account factors that contribute toward the initial development of the mask and that drive its maintenance.

Lay summary

Why is this topic important?: Autistic masking is a complicated topic. We currently think that masking includes things such as making eye contact even if it makes you feel uncomfortable, or not talking about your interests too much for fear of being labeled "weird." There is a lot about masking that we do not know yet, but it is important to understand masking as we think that it might have a negative effect on autistic people.What was the purpose of this article?: The purpose of this article was to look at current explanations of masking, and try to figure out what is missing.What do the authors conclude?: We conclude that work on masking needs to think about autistic people in a different way. Autistic people grow up in a social world and experience a lot of negative views about autism and autistic people. We argue that we need to understand how this social world and the trauma that can come from being part of it contributes toward masking. We also argue against the idea that masking is a "female" thing that occurs as a result of there being a "female-specific" subtype of autism, because this might make it harder for some people to get a diagnosis (e.g., nonbinary people, and men and women who do not fit with any of the current criteria). Instead we argue that people need to recognize that autism does not look like one "type" of person, and try to separate ideas about masking from ideas about a person not fitting a stereotype.What do the authors recommend for future research on this topic?: Though masking is called a "social strategy," there has not been a lot of social theory applied to masking research. We recommend that researchers use theories about how people try to fit in, and theories about how people exclude and hurt people who are different. This can help us to understand why autistic people mask. We also stress the need to understand that masking is not necessarily a choice, and that there are many unconscious aspects. We argue that researchers should try to find out when masking starts to happen (e.g., in childhood) and what makes people feel like they need to keep up the mask. We also recommend lot more research into autistic identity, and how different parts of identity (including things such as gender, race, and co-occurring conditions) might mean that someone has to mask more (or less), or in different ways.How will this analysis help autistic adults now and in the future?: We hope that this analysis will help researchers to understand that some aspects of masking might be unique to autistic people, but some aspects might be like other kinds of "pretending to be normal" that other people who are socially excluded use to try and fit in. We hope that our suggestions can help to improve our understanding of masking, and lead to research that makes life better for autistic people.

Toward a Gender-Sensitive Approach of Psychiatric Rehabilitation in Autism Spectrum Disorder (ASD): A Systematic Review of Women Needs in the Domains of Romantic Relationships and Reproductive Health

Later age of diagnosis, better expressive behaviors, increased use of camouflage strategies but also increased psychiatric symptoms, more unmet needs, and a general lower quality of life are characteristics often associated with female gender in autism spectrum disorder (ASD). Psychiatric rehabilitation has shown small to moderate effectiveness in improving patients' outcomes in ASD. Few gender differences have been found in the response to psychiatric rehabilitation. This might be related to the predominance of males in research samples, but also to the lack of programs directly addressing women's unmet needs. The objectives of the present paper were: (i) to review the needs for care of autistic women in romantic relationships and reproductive health; (ii) to review the existing psychosocial treatments in these domains; and (iii) to evaluate the strengths and limitations of the current body of evidence to guide future research. A systematic electronic database search (PubMed and PsycINFO), following PRISMA guidelines, was conducted on autistic women's needs for care relating to psychiatric rehabilitation in romantic relationships and reproductive health. Out of 27 articles, 22 reported on romantic relationships and 16 used a quantitative design. Most studies were cross-sectional (n = 21) and conducted in North America or Europe. Eight studies reported on interventions addressing romantic relationships; no published study reported on interventions on reproductive health or parenting. Most interventions did not include gender-sensitive content (i.e., gender variance and gender-related social norms, roles, and expectations). Autistic women and autistic gender-diverse individuals may face unique challenges in the domains of romantic relationships and reproductive health (high levels of stigma, high risk of sexual abuse, increased psychiatric symptoms, and more unmet needs). We discussed the potential implications for improving women's access to psychiatric and psychosocial treatment, for designing gender-sensitive recovery-oriented interventions, and for future research.

Sex Differences in Gender-Diverse Expressions and Identities among Youth with Autism Spectrum Disorder

A growing body of evidence supports a potential link between autism spectrum disorder (ASD) and gender dysphoria, yet few studies have looked at sex differences in the co-occurrence of gender diversity and ASD. The aim of this study was to characterize sex differences in gender-diverse expressions and identities, as well as gender-related concerns, in youth with ASD. Parents of youth with ASD ages 6-21 (n = 163) completed an online questionnaire about their child's gender expression and identity. Sex-typed behaviors during childhood were measured using the Gender Identity Questionnaire (GIQ). Semi-partial Kendall correlations and chi-square tests were used to compare gender non-conformity, gender-diverse identities, and gender-related concerns between sexes. Sex-based differences in mean GIQ score and individual GIQ items were evaluated using a linear regression and semi-partial Kendall correlations, respectively. All regressions and correlations controlled for child age. Parents of girls were more likely to report child appearances and mannerisms that were less concordant with their child's birth sex. Based on parent-report, girls had lower mean GIQ scores, indicating greater cross-gendered/fewer same-gendered behaviors in childhood. Lastly, parents of girls with ASD were more likely to report that their daughters experienced anxiety due to gender-related concerns and discomfort during puberty than parents of boys. These findings suggest that girls with ASD seem more likely have gender-diverse preferences, mannerisms, and appearances that fall outside of traditional gender norms. Gender-related concerns appear to be a source of real distress in girls with ASD, highlighting the need for individualized support, especially during puberty. LAY SUMMARY: Despite evidence of a potential link between autism and gender diversity, few studies have explored differences in gender identity/expression between boys and girls with autism. Based on parent responses, we found that girls with autism are more likely than boys to have appearances and mannerisms, as well as behaviors during childhood, that fall outside of the traditional gender role. The unique profile of girls with autism and their elevated distress over gender-related concerns call for individualized support during adolescence.

An Exploratory Study of a Dimensional Assessment of the Diagnostic Criteria for Autism

Prevalence rates of autism based upon child samples have shown a consistent increase over the past three decades, suggesting that many autistic adults are undiagnosed. Adult diagnostic pathways typically are initiated with measures of autistic-like traits. Whilst autistic-like traits represent a continuous dimension across the general population, autism is a categorical diagnosis and the relationship between the two is unclear. A self-report dimensional reflection upon the two diagnostic criteria for autism was developed and reflected upon by 1076 participants embedded within two online surveys. Those with an informal (self) diagnosis of autism self-reported comparable social difficulties but fewer restricted and repetitive behaviour difficulties than those with a formal diagnosis of autism. The new items also significantly correlated with autistic-like traits.

Social Capital and Autism in Young Adulthood: Applying Social Network Methods to Measure the Social Capital of Autistic Young Adults

Social isolation is a core challenge associated with autism. Interpersonal relationships and the resources and support embedded in the social networks of autistic young adults could impact key adult outcomes, including quality of life, mental health, employment, and independence. However, little research systematically measures the networks of autistic young adults and network impact on key adult outcomes. This article demonstrates how social network analysis can be adapted for the field of autism to measure young adult networks. We provide examples as to how this approach could be implemented to yield key insights into the amount and quality of interpersonal relationships and the types of resources embedded in the networks of autistic young adults. The network protocol was feasibility tested with autistic adults during the posthigh school transition period (n = 17, 19–27 years). The parents of three of the recruited young adults also successfully completed a complementary network survey, allowing for the inclusion of the parent-reported network using duocentric network analysis, never before applied to parent–child networks. The implementation data collected from the study suggest feasibility of egocentric and duocentric approaches, with several important modifications to adapt the measure for the field of autism. The future potential of social network research for understanding autism in adulthood is discussed.

What was the purpose of this study?

Many autistic young adults are disconnected from people, communities, and organizations that could provide them with valuable social resources to support their transition to adulthood. This study tests the feasibility of using social network methods to measure the resources that autistic young adults gain from their social connections. Future studies using our social network measure might provide valuable information about possible interventions that could help autistic youth acquire the social resources needed for successful adult outcomes.

What did the researchers do?

To test the feasibility of our social network measure, 17 autistic adults, between the ages of 19 and 27 years, were recruited to complete a survey about their social connections and the resources provided to them by their social connections. The parents of three of the autistic adults were also surveyed to provide information about the social connections that they relied on to help their autistic young adult to transition successfully.

What were the results of the study?

All participants successfully completed our survey online. We analyzed the network data to illustrate what types of information the survey produced. We demonstrated how the survey captures different types of support that people gained from their networks. We also used network pictures to show how network measures characterize connections among supporters of autistic young adults. This research successfully lays the groundwork for future studies to test whether the social resources young adults on the autism spectrum receive from their networks impact their adult outcomes.

What do these findings add to what is already known?

We know very little about the social networks for young adults on the autism spectrum. Also, no studies have used duocentric network analysis to measure the social capital of youth and their parents together. This project produced new useful ways of collecting social network data from young autistic adults that will produce knowledge about how to help young adults on the autism spectrum build networks that will yield the social resources needed to support positive adult outcomes.

What are potential weaknesses of this study?

The study was only designed to test the feasibility of the social network measure and does not provide generalizable information about how networks might impact outcomes. Also, the social network measure only allowed participants to identify five people, possibly under-reporting the actual size and composition of autistic young adult networks.

How will these findings help young adults on the autism spectrum now or in the future?

If future research suggests that social network factors help young adults on the autism spectrum to improve outcomes, then network interventions, guided by social network data, can be created.

Links Between Autistic Traits, Feelings of Gender Dysphoria, and Mentalising Ability: Replication and Extension of Previous Findings from the General Population

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.

The Female Autism Phenotype and Camouflaging: a Narrative Review

Autism is more commonly diagnosed in males than females. One explanation is the ‘female protective effect’: there is something inherent in being female which reduces the likelihood of developing autism. However, evidence suggests that the condition is underdiagnosed in females, perhaps because females express their autism in ways which do not meet current diagnostic criteria. This review explores evidence for a female-typical autism presentation, the Female Autism Phenotype (FAP) and the component of camouflaging (compensating for and masking autistic characteristics) in particular. The evidence so far supports the existence of a female-typical autism presentation, although further examination of the characteristics and their impact across all genders and ages is needed.

Feasibility and preliminary efficacy of a parent-mediated sexual education curriculum for youth with autism spectrum disorders

Youth with autism spectrum disorder can face social-communication challenges related to sexuality, dating, and friendships. The purpose of this study was to assess the feasibility, acceptability, and preliminary efficacy of the Supporting Teens with Autism on Relationships program. In total, 84 youth with autism spectrum disorder aged 9 to 18 and their parents participated in this study; two groups received the Supporting Teens with Autism on Relationships program (interventionist-led parent group vs parent self-guided), while an attentional control group received a substance abuse prevention program that included instruction in problem-solving and social skills. Feasibility and acceptability of the Supporting Teens with Autism on Relationships program was high overall. The Supporting Teens with Autism on Relationships program was effective in increasing parent and youth knowledge of sexuality, while the attentional control was not. There was preliminary support for improvement in parenting efficacy related to discussing sexuality with their children. Gains were seen among completers regardless of whether the parent received support from a facilitator. Implications and future directions are discussed.

Gender differences in self-reported camouflaging in autistic and non-autistic adults

Social camouflaging describes the use of strategies to compensate for and mask autistic characteristics during social interactions. A newly developed self-reported measure of camouflaging (Camouflaging Autistic Traits Questionnaire) was used in an online survey to measure gender differences in autistic ( n = 306) and non-autistic adults ( n = 472) without intellectual disability for the first time. Controlling for age and autistic-like traits, an interaction between gender and diagnostic status was found: autistic females demonstrated higher total camouflaging scores than autistic males (partial η2 = 0.08), but there was no camouflaging gender difference for non-autistic people. Autistic females scored higher than males on two of three Camouflaging Autistic Traits Questionnaire subscales: Masking (partial η2 = 0.05) and Assimilation (partial η2 = 0.06), but not on the Compensation subscale. No differences were found between non-autistic males and females on any subscale. No differences were found between non-binary individuals and other genders in either autistic or non-autistic groups, although samples were underpowered. These findings support previous observations of greater camouflaging in autistic females than males and demonstrate for the first time no self-reported gender difference in non-autistic adults.

A Review Update on Gender Dysphoria and ASD and Response to Corrections

Here we address the earlier published review by Øien et al. (J Autism Dev Disord, https://doi.org/10.1007/s10803-018-3686-7 , 2018) and the subsequent comments by Zucker and VanderLaan (J Autism Dev Disord, https://doi.org/10.1007/s10803-018-3748-x , 2018). The current commentary is a response to the corrections put forth by the latter authors where aspects related to diagnostic criteria of Gender Dysphoria and corrections to the existence of a control group were noted. Additionally, to highlight that research on Gender Dysphoria and ASD is becoming a very fast and growing field we also present an update of the original review which show a 13% increase of empirical studies published only in the past few months.
