Efficacy of Cognitive Behavioral Therapy in Treatment of Adults With Attention Deficit Hyperactivity Disorder
Study Details
Study Description
Brief Summary
The purpose of the project is to evaluate the efficacy of cognitive behavioral therapy (CBT) for adults with attention deficit hyperactivity disorder (ADHD) with and without stimulant medication and compare it to medication alone. Subjects will be randomly assigned to stimulant medication only, CBT only and combined CBT and stimulant medication group. Patients will be evaluated at baseline, following mediation optimization (for medicated groups), following 12 months of treatment, after 3 months of follow up, and after 6 months of follow up. The investigators hypothesize that the combined group will have the best outcome at all evaluation points. ADHD in adults is associated with significant morbidity and impaired academic, occupational, social, and emotional functioning. Developing optimal treatment approaches for this population is key in improving their functioning.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Medication only Stimulant medication (methylphenidate or amphetamine product approved for clinical use in Canada), with dose optimized for each patient based on report of efficacy and side effects. |
Drug: methylphenidate or amphetamine product
Medication is titrated over a 4-week period with stepwise increments each week. Patients and significant others complete ADHD symptom scales at baseline and before each medication visit. Patients also complete side effects scales at baseline and before each medication visit. The gradual increase will continue until there is no further improvement in symptoms and in the Clinical Global Improvement Scale or side effects are such that further increases are not indicated. Once the optimal dose is reached, the subjects remain on this dose for the remainder of the study.

Behavioral: Cognitive behavioral therapy
12 sessions of group cognitive behavioral therapy. Participants also receive individual coaching 3 times a week (twice over telephone and once in person). Coaching sessions are 15 minutes each in duration and are aimed at implementation, practice, and generalization of skills acquired in therapy.

| Experimental: Cognitive behavioral therapy alone 12 weeks of structured group cognitive behavioral therapy, focusing on acquisition of skills in organization, time management, goal attainment, cognitive restructuring, stress management, anger management, impulse control, self-esteem, and relationship management. |
