Abstract: | Relapse and recurrence following response to acute-phase treatment for major depressive disorder (MDD) are prevalent and costly. In a meta-analysis of 28 studies including 1,880 adults, the authors reviewed the world's published literature on cognitive-behavioral therapies (CT) aimed at preventing relapse-recurrence in MDD. Results indicate that after discontinuation of acute-phase treatment, many responders to CT relapse-recur (29% within 1 year and 54% within 2 years). These rates appear comparable to those associated with other depression-specific psychotherapies but lower than those associated with pharmacotherapy. Among acute-phase treatment responders, continuation-phase CT reduced relapse-recurrence compared with assessment only at the end of continuation treatment (21% reduction) and at follow-up (29% reduction). Continuation-phase CT also reduced relapse-recurrence compared with other active continuation treatments at the end of continuation treatment (12% reduction) and at follow-up (14% reduction). The authors discuss implications for research and patient care and suggest directions, with methodological refinements, for future studies.
