Adaptive behavior and psychiatric symptoms in university students with ASD: One-year longitudinal study

In recent years, more young adults with ASD are attending post-secondary education, and several support programs have been proposed for this population. However, research regarding the long-term effects of university enrollment on outcomes among students with ASD is scarce. This study examined adaptive behavior and psychiatric symptoms during the first semester of two consecutive academic years (T1, T2) among 39 students with ASD, 29 students without ASD and high levels of social anxiety symptoms (High SA), and 32 students without ASD and low levels of SA symptoms (Low SA). Students with ASD participated in a university support program and resided with a peer mentor student without ASD, which encouraged social interaction. At T1, students with ASD reported lower levels of adaptive behavior and higher levels of social anxiety and obsessive-compulsive symptoms compared to the other groups. However, at follow-up (T2), significantly higher conceptual adaptive skill levels (specifically communication skills) and significantly lower depression symptom levels from T1 were reported only among students with ASD. The levels of social anxiety and obsessive-compulsive symptoms at T1 were negatively associated with adaptive functioning a year later (T2). Implications regarding adults with ASD attending university are discussed.
