Exploratory Study of Executive Function Abilities Across the Adult Lifespan in Individuals Receiving an ASD Diagnosis in Adulthood
The few studies of autism spectrum disorder (ASD) across adulthood suggest different age-related associations in different aspects of executive function (EF). In this exploratory study we examined EF abilities and self-report autism traits in 134 adults (aged 18-75 years; mean=31 years) with abilities in the normal range, receiving a first diagnosis of ASD. Results suggest that in some EF relying on speed and sequencing (Trails A and B; Digit Symbol), late-diagnosed ASD individuals may demonstrate better performance than typical age-norms. On other EF (Digit Span, Hayling, Brixton tests) age-related correlations were similar to typical age-norms. Different domains of EF may demonstrate different trajectories for ageing with ASD, with patterns of slower, accelerated or equivalent age-related change observed across different measures

Measuring the Autistic Women's Experience (AWE).
Peer reviewed: TruePublication status: PublishedWe developed a Dutch questionnaire called the Autistic Women's Experience (AWE) and compared its psychometric properties to the Autism Spectrum Quotient (AQ). Whilst attenuated gender differences on the AQ have been widely replicated, this instrument may not fully capture the unique experience of autistic women. The AWE was co-developed with autistic women to include items that reflect autistic women's experience. We investigated the AWE (49 items) and compared it with the AQ (50 items) in Dutch autistic individuals (N = 153, n = 85 women) and in the general population (N = 489, n = 246 women) aged 16+. Both the AQ and AWE had excellent internal consistency and were highly and equally predictive of autism in both women and men. Whilst there was a gender difference on the AQ among non-autistic people (men > women), there was no gender difference among autistic people, confirming all earlier studies. No gender differences were detected on the AWE overall scale, yet subtle gender differences were observed on the subscales. We conclude that the AQ is valid for both genders, but the AWE provides an additional useful perspective on the characteristics of autistic women. The AWE needs further validation in independent samples using techniques that allow for testing gender biases, as well as a confirmatory factor analysis in a larger sample
