Adjustment Across the First College Year: A Matched Comparison of Autistic, Attention-Deficit/Hyperactivity Disorder, and Neurotypical Students.

Background: Although the number of autistic students attending higher education has grown substantially in recent decades, little is known about factors that support their retention and persistence in college. First-year experiences and adaptability to the college environment greatly impact students' decisions to remain enrolled. Despite the importance of first-year adjustment to persistence and retention, few studies have examined the adjustment experiences of first-year autistic students compared to those of matched nonautistic students.

Methods: This study used national survey data to compare the first-year college adjustment experiences of 222 freshmen, including 74 self-identified autistic students, 74 students with attention-deficit/hyperactivity disorder (ADHD), and 74 students without diagnoses (referred to as neurotypical; NT), matched on mental health and demographic characteristics. Students were compared on measures of academic, social, emotional, and institutional adjustment at the end of freshman year. Separate general linear models were used to investigate predictors of positive self-reported first-year adjustment.

Results: Autistic students reported significantly lower levels of social self-confidence than their NT and ADHD peers at the end of freshman year. On all other adjustment domains, students in the autism, ADHD, and NT groups did not significantly differ. Autistic students were not significantly different from their ADHD and NT peers in terms of satisfaction with their college experience or sense of belonging to their institution. Social factors, including social self-confidence and ease of making friends, emerged as important contributors to positive first-year adjustment outcomes across all groups.

Conclusions: When controlling for demographic factors and mental health characteristics entering college, autistic students do not significantly differ from their NT and ADHD peers on several domains of college adjustment. Future studies should further investigate the impact of mental health and student characteristics on college trajectories and outcomes for autistic students.
