Revisiting the Link: Evidence of the Rates of Autism in Studies of Gender Diverse Individuals.

Turban and van Schalkwyk assert in their Translations article, "'Gender Dysphoria' and Autism Spectrum Disorder: Is the Link Real?" that an over-representation of autism spectrum disorder (ASD) in gender dysphoria is unsupported based on current evidence. Turban and van Schalkwyk discuss 7 of the currently 19 available empirical studies (excluding reviews and case reports) of the over-occurrence of ASD and/or autism traits with gender dysphoria/diversity. They are correct to note that some ASD screeners may lack specificity; that is, a clinical-range total score could indicate non-ASD-related mental health conditions or other developmental difference. However, they do not account for the 7 available studies which specifically report rates of clinical diagnoses of ASD among unselected gender-diverse samples. We suggest also that many of the studies that assess ASD-symptoms in gender-diverse groups are more convincing than suggested by Turban and van Schalkwyk because they employ measures assessing the multi-dimensionality of ASD symptoms and report significant elevations not only for socially-related symptoms but also for the various components of restricted and repetitive behaviors and interests (RRBI) core to ASD. We come together to write this response as gender clinicians and researchers, autism clinicians and researchers, and key stakeholders, including autistic and autistic transgender self-advocates. We work and live with the co-occurrence of autism and gender diversity on a daily basis, and we are concerned that perpetuating misunderstanding about the co-occurrence places individuals at risk.

What About the Girls? Sex-Based Differences in Autistic Traits and Adaptive Skills.

There is growing evidence of a camouflaging effect among females with autism spectrum disorder (ASD), particularly among those without intellectual disability, which may affect performance on gold-standard diagnostic measures. This study utilized an age- and IQ-matched sample of school-aged youth (n = 228) diagnosed with ASD to assess sex differences on the ADOS and ADI-R, parent-reported autistic traits, and adaptive skills. Although females and males were rated similarly on gold-standard diagnostic measures overall, females with higher IQs were less likely to meet criteria on the ADI-R. Females were also found to be significantly more impaired on parent reported autistic traits and adaptive skills. Overall, the findings suggest that some autistic females may be missed by current diagnostic procedures.

Sex differences in parent-reported executive functioning and adaptive behavior in children and young adults with autism spectrum disorder.

This study is the largest to date examining executive function and adaptive skills in females with autism spectrum disorder (ASD). Its primary aim was to utilize parent ratings of real-world executive functioning and adaptive behavior to better understand whether females with ASD differ from males with ASD in these areas of everyday functioning. We compared 79 females with ASD to 158 males with ASD (ages 7-18) who were statistically matched on age, IQ, and level of ADHD or ASD traits. All participants were assessed using the Behavior Rating Inventory of Executive Function (BRIEF) and a subset (56 females and 130 males) also received the Vineland Adaptive Behavior Scales (VABS). Females were rated by parents as having greater problems with executive function on the BRIEF. Parents also rated females as exhibiting more difficulties than males on the Daily Living Skills domain of the VABS. There was a correlation between increased global EF difficulty and decreased adaptive ability in both males and females. Our results indicate relative weaknesses for females compared to males diagnosed with ASD on executive function and daily living skills. These differences occur in the absence of sex differences in our sample in age, IQ, clinician ratings of core ASD symptomatology, parent ratings of ADHD symptoms, and parent-reported social and communication adaptive skills on the VABS. These findings indicate specific liabilities in real world EF and daily living skills for females with ASD and have important implications for targeting their treatments.

Reliability and validity of methods for measuring the duration of untreated psychosis: a quantitative review and meta-analysis.

BACKGROUND: The duration of untreated psychosis (DUP) has been associated with a wide range of clinical outcomes, and is considered to be one of the key parameters in managing clinical high risk and first episode psychosis patients. However, considerable discrepancies exist in the way that DUP is estimated in different studies. There is no standard or consensus on which method is most reliable and valid for assessing DUP. METHODS: This review aimed to quantitatively assess different DUP measurement instruments and definitions by comparing their inter-rater reliability, and their strength of validity in predicting biological and clinical outcomes. RESULTS: Nine instruments designed for measuring DUP were found. Their inter-rater reliability were found to be adequate to excellent, although quite varied. This analysis did not show that any instrument was clearly outstanding compared to the others, although the limited available data do not exclude this possibility. DUP was also significantly associated with a range of outcomes, although mostly with small effect sizes. However, non-instrument based, ad hoc clinical interviews remained the most common way of measuring DUP. Definitions of onset of psychosis and onset of treatment were inconsistent among studies. CONCLUSIONS: This review did not find quantitative evidence to support the use of one instrument over another. DUP remains a promising modifiable risk factor for a range of long-term clinical outcomes. Future research should quantify and improve the reliability and validity of the structured instruments for DUP measurement.

The role of social media networks in psychotic disorders: a case report.

We report the case of a young man diagnosed with schizophrenia who presented with stalking behaviors that may have been caused by problematic use or participation in social media networks (SMN). We review the possible role of SMN in the formation of his romantic delusion and offer suggestions for clinicians around incorporation of SMN questions into assessments. It is imperative to identify populations at risk of SMN-related stalking behaviors to stratify mental health resources and interventions. Additional studies are needed to further clarify the role of SMN in psychotic disorders.
