Research Review: A systematic review and meta-analysis of sex differences in narrow constructs of restricted and repetitive behaviours and interests in autistic children, adolescents, and adults.

BACKGROUND: Evidence that autism often manifests differently between males and females is growing, particularly in terms of social interaction and communication, but it is unclear if there are sex differences in restricted and repetitive behaviours and interests (RRBIs) when rigorously focusing on the narrow construct level (i.e., stereotyped behaviour, restricted interests, insistence on sameness, and/or sensory experiences). METHODS: We conducted a systematic review and four random effects meta-analyses investigating sex differences in narrow construct measures of RRBIs in autistic children, adolescents, and adults (Prospero registration ID: CRD42021254221). Study quality was appraised using the Newcastle-Ottawa Quality Assessment Scale. RESULTS: Forty-six studies were narratively synthesised and 25 of these were included in four random effects meta-analyses. Results found that autistic males had significantly higher levels of stereotyped behaviours (SMD = 0.21, 95% confidence interval (CI) [0.09, 0.33], p < .001) and restricted interests (SMD = 0.18, 95% CI [0.07, 0.29], p < .001) compared to autistic females. In contrast, there were no significant sex differences for sensory experiences (SMD = -0.09, 95% CI [-0.27, 0.09], p = .32) and insistence on sameness (SMD = 0.01, 95% CI [-0.03, 0.05], p = .68). The findings from the narrative synthesis were generally consistent with those from the meta-analyses and also found qualitative sex differences in the way RRBIs manifest. CONCLUSIONS: Our findings show significant differences in narrowly defined RRBIs in males and females. Practitioners need to be aware of such differences, which could be contributing to the under-recognition of autism in females and may not be captured by current diagnostic instruments.

What do measures of gender identity tell us about gender identity over time?

Gender identity is a multifaceted concept and is represented by a wide range of measures and constructs including both self-report and researcher observations of preferences and behaviours. However, despite their similar theoretical underpinning, gender identity measures are rarely found to correlate with one another, and contrasting patterns and trajectories are often found for each construct (Egan & Perry, Developmental Psychology, 37, 2001, 451). Therefore, this systematic review aimed to present a review of the longitudinal research evidence surrounding gender identity development in the absence of formal intervention. Using a systematic search strategy, 21 studies were identified. Narrative synthesis was used to synthesize the data collected in these studies and trajectories were explored for (1) self-identification measures of gender identity, (2) clothing preferences, (3) peer preferences, and (4) object/activity preferences. Overall, the results of this systematic review are consistent with wider research suggesting that distinct developmental patterns can be observed when using different constructs and measures of gender identity.

Navigating the landscape: Roles, perspectives, and experiences of psychologists supporting gender diverse children and young people in school settings.

Purpose: This review aimed to explore and synthesize the perspectives and experiences of school-based psychological professionals providing support to gender diverse CYP across the world, to foreground the voices of those with relevant experience and support future practice. Methods: A systematic review of five databases (PsychINFO, CINAHL, ERIC, SCOPUS and PROQUEST dissertations and theses) was performed between September and November 2022. Articles were included if they contained qualitative, primary research data representing the voice of at least one school-based psychological professional with experience working with gender diverse children and young people. Articles were excluded if they did not contain primary research data, were quantitative, related to non-school based psychologists or focussed on participant views in the absence of direct experience working with gender diverse pupils. Articles were thematically summarized and organized into a data extraction table. Results: Eighteen studies were identified for review, including 11 studies based in the USA, five in the UK, one in Australia and one in Cyprus. The voices of school-based professionals, including school counselors, school psychologists, trainee and qualified educational psychologists, were represented. The themes created highlighted the importance of the environment in which psychologists were working, the reliance on their own views and values to guide their work in the absence of clear guidance, the role psychologists saw they had to advocate for gender diverse CYP, as well as barriers and systems they were fighting against. Conclusion: The review highlighted the need for psychologists to advocate for gender diverse children and young people, in an often non-inclusive environment where there was a need to work systemically with schools. Future research is needed to explore young people's experiences of the support that they are receiving and would like to receive.

"If You're Not Yourself, Who are You Going to be?" an Exploration of Gender and Sexuality Diverse Pupils Experiences of Visibility Management in School: A Systematic Literature Review.

Like all young people (YP), those who are gender and sexuality diverse (GSD) spend their youth exploring and discovering their identities; but unlike their peers, they must consider whether, how, and when to disclose their GSD identity to others in a dynamic process of visibility management (VM). At school, GSD YP actively test social reactions, interpret attitudes, and assess safety, ultimately seeking belonging as their authentic selves. Our systematic review explored findings from 16 qualitative studies capturing GSD YPs experiences of managing visibility in schools internationally. Data were thematically synthesized, and seven themes were constructed. The process of visibility management is fluid, a negotiation with social norms that GSD YP's very existence transgresses. YP search for, and through activism actively shape, accepting environments in which they can safely be their authentic selves. GSD YP are actively asking school staff for help in creating open communities where all YP can find a place to belong, to fight to be visible. We offer some suggestions for how we might begin.
