Approximately 1% (<jats:italic>n<\/jats:italic>\u00a0=\u00a0251) endorsed high autistic traits, henceforth the Autism Spectrum Traits (AST) group.

Elevated current PTSD symptoms were reported by AST compared to COA. An interaction was observed between autistic traits and trauma severity; the effect of level of trauma on PTSD symptoms was significantly greater for AST versus COA participants. This interaction remained significant when controlling for current depression and anxiety symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings suggest that high autistic traits may increase the likelihood of experiencing trauma across the lifespan, and the impact of severe trauma on PTSD symptoms. Older adults with high (vs. low) autistic traits may be at greater risk of experiencing PTSD symptoms in latter life. Future research should test whether the pattern of results is similar for diagnosed autistic adults.<\/jats:p><\/jats:sec>","DOI":"10.1002\/gps.5669","type":"journal-article","created":{"date-parts":[[2021,12,23]],"date-time":"2021-12-23T15:15:16Z","timestamp":1640272516000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Traumatic
