Findings From the Treatment for Adolescents with Depression Study (TADS): What Have We Learned? What Do We Need to Know?

Abstract

This introduction to the special section on findings from the Treatment for Adolescents with Depression Study provides a review of the rationale for the study, its design, and principal findings to date. Findings with regard to acute effectiveness of alternative treatments, relapse, recurrence, maintenance of gains, and the effects of treatment on suicidal ideations and suicidal behavior are reviewed. We conclude with a brief discussion of unresolved clinical issues, including treatment resistance, management of partial response, moderators and predictors of long-term response, and mediators of clinical change. The articles of the special section address a range of issues including relations between cognitive factors associated with depression, relations between maladaptive beliefs and treatment response, cognitive mediators of therapeutic improvement, relations between family conflict and treatment response, and the economic costs of adolescent depression.
