Gender Differences in Autism Spectrum Disorders in a Population-Based Twin Sample, 2016-2019

This data collection is associated with a large population-based twin study of gender differences in autism. The data were collected from 2016-2019 from a sample population based in the UK. All participants were aged between 20-24 years of age at the time of data collection. The data deposited in this collection are taken from in-home assessments and accompanying questionnaires completed by the twins. The collection includes data from Autism Diagnostic Observation Schedule -2 assessments, the Social Responsiveness Scale (2nd edition) (a measure of autism traits), WASI IQ assessments, Strengths and Difficulties Questionnaire total domain scores (a measure of aspects of mental health) and the WHOQoL Bref (a measure of quality of life). Also included in the collection are demographic information for the participants including sex, age, zygosity and a grouping variable to indicate whether they were included in the study’s diagnosed, high trait or co-twin sample groups.
