The association between autistic spectrum disorder and psychotic experiences in the Avon Longitudinal Study of Parents and Children (ALSPAC) Birth Cohort

Research output: Contribution to journalArticle (Academic Journal)peer-review

Abstract

Objective: Studies report overlap between autism spectrum disorders and psychosis. This may indicate a relationship between the two disorders or an artificial overlap due to similarity of symptoms. The aim of this study was to investigate whether autism spectrum disorder and autistic traits predict psychotic experiences in early adolescence.
Method: This study analyses prospective data from a cohort. A dataset of 5359 cohort members was analysed who had provided data on autistic traits and/or a diagnosis of an autism spectrum disorder and psychotic experiences at age 12.
Results: A diagnosis of an autism spectrum disorder (OR 2.81 95% CI 1.07, 7.34 p=0.035) and childhood autistic traits (OR 1.15 95% CI 1.05, 1.26 p=0.0018) were associated with psychotic experiences after adjustment for confounders.
Conclusions: These findings suggest a shared neuro-developmental origin for autism and psychosis.
