Maintenance of gains versus relapse following brief psychotherapy for depression

Cross-sectional and longitudinal data are presented from a 2-year follow-up study of 91 older adults, initially diagnosed as in an episode of major depressive disorder (MDD), who were treated with brief cognitive, behavioral, or psychodynamic psychotherapy. Using research diagnostic criteria (RDC), 52%, 58%, and 70% of the sample did not meet criteria for any RDC depressive disorder at posttherapy, and 12- and 24-month follow-ups, respectively. There were no significant differences in response rate by therapy modality. Using Longitudinal Interval Follow-up Evaluation (LIFE; Shapiro & Keller, 1979; Keller et al., 1987) methodology, we noted that patients not depressed at posttreatment remained depression-free for longer time periods than those who were minor or MDD. These rates compare favorably with published reports on younger depressed patients.
