This study presents 2-year follow-up data of a comparison between complete cognitive–behavioral therapy for depression (CT) and its 2 major components: behavioral activation and behavioral activation with automatic thought modification. Data are reported on 137 participants who were randomly assigned to 1 of these 3 treatments for up to 20 sessions with experienced cognitive–behavioral therapists. Long-term effects of the therapy were evaluated through relapse rates, number of asymptomatic or minimally symptomatic weeks, and survival times at 6-, 12-, 18-, and 24-month follow-ups. CT was no more effective than its components in preventing relapse. Both clinical and theoretical implications of these findings are discussed.
