Heritability of autistic traits in the general population.

Objective: To explore genetic and environmental influences on individual differences in autistic traits in early adulthood and to test if there is assortative mating (non-random partner choice) for autistic traits in the general population. Design: Twin family study using structural equation modeling. Setting: Population-based twin family sample from the Netherlands. Participants: Twins aged 18 years (n=370) and their siblings (n=94); parents of twins (128 couples). Main Outcome Measure: Self-reported Autism-Spectrum Quotient (AQ) scores, a quantitative measure of autistic traits. Results: Aut... Mehr ...
