Autistic Traits in Men With Substance Use Disorder.

There has been no study in the literature evaluating autistic traits (ATs) in men with substance use disorders (SUDs). Therefore, we performed the current study to evaluate whether there is a relation between the ATs among men with SUDs and normal controls. A total of 142 men with SUDs and 109 age and sex-matched healthy controls were included in the current study. Present attention deficit hyperactivity disorder (ADHD) symptoms of the participants were evaluated using the Adult ADHD Self-Report Scale. The autism spectrum quotient (AQ) was used to evaluate ATs. The current study found that higher AQ imagination and lower AQ attention to detail scores predicted SUDs after controlling for AQ subscales and present ADHD symptoms. This study shows that ATs may be engaged in the development of SUDs. To explore the connection between ATs and SUDs, more research is needed.
