ADHD, previously believed to be a disorder of childhood, affects as many as 5 percent of adults. Adults with ADHD are at high risk for academic and occupational underachievement, relationship difficulties, and reduced quality of life. This study will determine whether CBT is more effective than ADHD education and relaxation techniques in treating adults with ADHD.

Participants will be randomly assigned to receive 12 to 15 weekly sessions of either CBT or training in which they will learn relaxation techniques and receive detailed information about ADHD. Questionnaires will be used to assess participants'''' ADHD symptoms at study entry and at study completion.

Study hypothesis: CBT is a more efficacious treatment for adult ADHD than education and relaxation techniques.
