Anthony Spirito, PhD, is Professor and Director of the Division of Clinical Psychology in the Department of Psychiatry and Human Behavior. He conducts treatment research with depressed, suicidal, and substance-using adolescents and their parents. Dr. Spirito has been conducting research in adolescent suicidality and depression for 25 years. He is currently conducting treatment development studies to determine if new approaches will increase the efficacy of depression treatments for adolescents. The first trial is examining whether concurrently treating the depressed parent of a depressed teen will improve outcomes for the adolescent. The second study is examining whether the addition of an exercise component to a CBT protocol will improve depression outcomes in overweight adolescents treated with CBT. The third trial is testing an integrated approach for treating conduct problems in depressed adolescents.
