The present study examined the effectiveness of interpersonal group therapy designed to improve self-esteem and social functioning in college students with Attention-Deficit/Hyperactivity Disorder (ADHD). Participants with documented ADHD diagnoses completed self-report measures of self-esteem and social functioning at the initiation of the study, after 6 weeks, and at 12 weeks. Half the participants completed a 12-week interpersonal group therapy while the other half served as a control group matched by gender and age. Findings suggest that interpersonal group therapy improves self-esteem, psychosocial competence, and emotional maturity, and should be a treatment option for college students with ADHD. Implications for practice are discussed.
