Psychiatric symptoms and psychosocial difficulties in young adults with autistic traits.

A screening version of the social responsiveness scale (SRS) was administered to 1,847 university students to identify a subgroup reporting significantly greater autism traits relative to their peers (High SRS group). A group reporting minimal autism traits was also identified (Low SRS group) matched for age, gender, and attentional difficulties. We administered the Behavioral Assessment System for Children-2nd edition (BASC-2), a comprehensive questionnaire designed to assess psychiatric symptoms and personality characteristics, to both groups. The high SRS group reported significantly more difficulties across the majority of areas, including depression/anxiety, interpersonal relationships, and personal adjustment. Thus, young adults reporting a greater degree of autistic traits also reported greater psychiatric difficulties across a wide psychosocial range.
