A study published in the latest issue of Psychotherapy and Psychosomatics indicates that the benefits of a specific psychotherapeutic approach may disappear after two years from the conclusion of the psychotherapy.
Evidence on the long-term efficacy of psychotherapeutic approaches for chronic depression is scarce. The purpose of the trial was to evaluate the effects of the Cognitive Behavioral Evaluation System of Psychotherapy (CBASP) compared to Supportive Psychotherapy (SP) 1 12 months and a pair of years after treatment termination.
This study presents the outcomes of the 1- and 2-year comply with-up assessments of a prospective, multicenter, evaluator-blinded, randomized scientific trial of outpatients with early-onset chronic major depression (n = 268). The initial treatment included 32 periods of CBASP or SP over 48 weeks. The first consequence was the speed of “effectively weeks” (Longitudinal Interval Follow-Up Evaluation; no/minimal signs) after one year and two years. The secondary outcomes had been, among others, clinician- and self-rated depressive symptoms, response/remission rates, and quality of life.
Of the 268 randomized patients, 207 (77%) participated in the follow-up. Within the intention-to-treat analysis, there was no statistically significant difference between CBASP and SP sufferers in experiencing weeks nicely and in remission rates within the two years after treatment. Statistically significant results have been present in favor of CBASP 1 year after treatment termination concerning the speed of well weeks, self-rated depressive symptoms, and depression-related quality of life.
CBASP lost its superiority over SP at some point between the first and the second year. This suggests the necessity of maintenance therapy for early-onset chronically depressed patients remitted with CBASP throughout the acute therapy phase.
