This study investigated the genetic and environmental origins of the co-occurrence of autistic traits, anxiety, and depression through a meta-analysis and a twin study. The meta-analysis of six twin studies revealed a genetic correlation of 0.42 and a non-shared environmental correlation of 0.15. The findings suggest overlapping influences across these traits.
Key findings
- Genetic correlation between autistic traits and internalising symptoms was 0.42.
- Non-shared environmental correlation was found to be 0.15.
- The twin study indicated a common latent factor influencing the co-occurrence of traits.
- Substantial heterogeneity was observed across estimates in the meta-analysis.
Why it matters
Understanding the shared genetic and environmental influences on autistic traits and internalising symptoms can inform screening practices. Clinicians may consider assessing for anxiety and depression in individuals with autistic traits, enhancing early intervention strategies.
