Objective: The effectiveness of a short (six session) individual cognitive behavioral planning intervention for college students with attention-deficit/hyperactivity disorder (ADHD) was tested. Method: In three student counseling services in Flanders, individuals with ADHD (N = 58) were randomized to the intervention or waitlist condition. Pre- and posttreatment assessments were conducted, and within the intervention group, a 4-month follow-up was conducted. Primary outcomes were ADHD symptoms and study skills; secondary outcomes were comorbid symptoms and planning skills on a neuropsychological task. Results: Intent-to-treat analyses showed a significant interaction on one outcome: inattention symptoms. The treatment condition improved from pretest to posttest, whereas the waitlist did not. Other measures showed large significant time effects (improved skills, reduction of symptoms in both groups) but no interactions. Stability analyses were not possible due to substantial dropout at follow-up. Conclusion: Specific treatment effects are on one outcome (inattention) and modest; for further implementation, the treatment needs adaptation.
