This study will determine the effectiveness of cognitive behavioral therapy (CBT) in
treating the symptoms of attention deficit hyperactivity disorder (ADHD) in adults who have
not responded to drug treatment.
Study hypothesis: CBT is an effective treatment for adult ADHD.
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 drug therapy in treating ADHD symptoms in adults who have been
resistant to previous drug therapies.
Participants will be randomly assigned to receive 12 to 15 weekly sessions of either CBT or
drug therapy which may include new or previously taken drugs. Questionnaires will be used to
assess participants’ ADHD symptoms at study start and at study completion.
