Estimated Prevalence of Attention-Deficit/Hyperactivity Disorder Symptoms Among College Freshmen Gender, Race, and Rater Effects

Group differences and prevalence rates for attention-deficit/hyperactivity disorder (ADHD) symptoms in a matched sample of college freshmen (n = 956) and their parents (n = 956) were investigated for gender and race (African American and Caucasian) effects using current self-report and retrospective parent-report ratings. On self-report, compared to female students, male students displayed higher mean scores on subscales and lower rates for reporting symptom totals beyond DSM-IV thresholds for the three subtypes of ADHD. Mean differences in ADHD symptoms were not apparent for race. However, African American students displayed higher rates for reporting symptom totals beyond DSM-IV thresholds for all subtypes. On retrospective parent report, male students and Caucasian students displayed higher mean scores on all scales and higher rates for reporting symptom totals beyond DSM-IV thresholds for all subtypes. Prevalence rates varied by gender and race on self-report and parent report. Prevalence was examined based on combined data of self-report and parent report and using age-adjusted cutoff criteria. Findings and implications are discussed.
