Two-Year Follow-Up after Treatment with the Cognitive Behavioral Analysis System of Psychotherapy versus Supportive Psychotherapy for Early-Onset Chronic Depression.

BACKGROUND: Evidence on the long-term efficacy of psychotherapeutic approaches for chronic depression is scarce. OBJECTIVE: To evaluate the effects of the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) compared to Supportive Psychotherapy (SP) 1 year and 2 years after treatment termination. METHODS: In this study, we present 1- and 2-year follow-up assessments of a prospective, multicenter, evaluator-blinded, randomized clinical trial of outpatients with early-onset chronic major depression (n = 268). The initial treatment included 32 sessions of CBASP or SP over 48 weeks. The primary outcome was the rate of "well weeks" (Longitudinal Interval Follow-Up Evaluation; no/minimal symptoms) after 1 year and 2 years. The secondary outcomes were, among others, clinician- and self-rated depressive symptoms, response/remission rates, and quality of life. RESULTS: Of the 268 randomized patients, 207 (77%) participated in the follow-up. In the intention-to-treat analysis, there was no statistically significant difference between CBASP and SP patients in experiencing well weeks (CBASP: mean [SD] of 48.6 [36.9] weeks; SP: 39.0 [34.8]; rate ratio 1.26, 95% CI 0.99-1.59, p = 0.057, d = 0.18) and in remission rates (CBASP: 1 year 40%, 2 years 40.2%; SP: 1 year 28.9%, 2 years 33%) in the 2 years after treatment. Statistically significant effects were found in favor of CBASP 1 year after treatment termination regarding the rate of well weeks, self-rated depressive symptoms, and depression-related quality of life. CONCLUSIONS: CBASP lost its superiority over SP at some point between the first and the second year. This suggests the necessity of maintenance treatment for early-onset chronically depressed patients remitted with CBASP during the acute therapy phase, as well as the sequential integration of other treatment strategies, including medication for those who did not reach remission.

The impact of childhood maltreatment on the differential efficacy of CBASP versus escitalopram in patients with chronic depression: A secondary analysis.

Childhood maltreatment (CM) has been indicated as a predictor of a differential response to antidepressant treatment with psychotherapy compared to medication. In this secondary analysis, we investigated whether the presence of CM results in a differential indication for the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) or escitalopram plus clinical management (ESC). Sixty patients with chronic depression were randomized to either 22 sessions of CBASP or ESC over the course of 8 weeks of acute and 20 weeks of extended treatment at 2 German treatment sites. CM was assessed using the Childhood Trauma Questionnaire and the clinician rated Early Trauma Inventory. Intention-to-treat analyses were used to examine the impact of CM on depression, global functioning, and quality of life. The presence of CM did not result in significant differences in treatment response to CBASP or ESC on any outcome measure after 28 weeks of treatment independent of the type of CM assessment. After 8 weeks, a significant CM × treatment interaction was found for scores on the Montgomery-Asberg Depression Rating Scale. Patients with a history of CM receiving CBASP had a significantly lower response rate compared to patients without CM and to those receiving ESC after 8 weeks. Conclusively, CBASP and ESC are equally effective treatment options for the difficult to treat subgroup of patients with chronic depression and a history of CM. CM may be a predictor of a longer latency of treatment response in the case of psychotherapy. KEY PRACTITIONER MESSAGE: CBASP and escitalopram are equally effective treatment options for chronic depression. Both treatments are also equally effective for the difficult to treat subgroup of patients with chronic depression and a history of childhood maltreatment. Childhood maltreatment may result in a longer latency of treatment response in the case of psychotherapy.

The Impact of Childhood Maltreatment on Long-Term Outcomes in Disorder-Specific vs. Nonspecific Psychotherapy for Chronic Depression.

BACKGROUND: Childhood maltreatment (CM) predicted poorer outcomes in acute depression treatment with CBT, IPT and Supportive Psychotherapy (SP). The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) fared well in patients with chronic depression and CM during acute treatment, yet there is a considerable lack of empirical evidence for long-term outcomes. METHODS: We analyzed one and two-year follow-up data of 268 patients randomized to 24 sessions (20 weeks) of acute and 8 sessions (28 weeks) of extended treatment with CBASP or SP. Primary outcome was the number of well weeks as measured by the Longitudinal Interval Follow-Up Evaluation Interview (LIFE). Secondary outcomes included self- and clinician-rated depression symptoms. We investigated this moderating effect for any CM and for specific subtypes of CM. RESULTS: Intent-to-treat analyses revealed that the presence of CM did not significantly moderate long-term effects of CBASP compared to SP. The analysis of trauma subtypes revealed that patients with childhood emotional abuse had statistically significant worse outcomes than patients without (main effect, p=.015) and that the advantage of CBASP over SP was larger in patients with childhood emotional abuse than in patients without (interaction effect, p=.045) after 1 year. No significant effects were found for other trauma subtypes. LIMITATIONS: The measurement of CM was limited to retrospective self-assessment. CONCLUSIONS: The presence of CM did not significantly moderate long-term treatment effects of CBASP compared to SP. When trauma subtypes were considered, CBASP was more effective than SP after one year in patients who retrospectively reported emotional abuse.

Effect of Disorder-Specific vs Nonspecific Psychotherapy for Chronic Depression: A Randomized Clinical Trial.

IMPORTANCE: Chronic depression is a highly prevalent and disabling disorder. There is a recognized need to assess the value of long-term disorder-specific psychotherapy. OBJECTIVE: To evaluate the efficacy of the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) compared with that of nonspecific supportive psychotherapy (SP). DESIGN, SETTING, AND PARTICIPANTS: A prospective, multicenter, evaluator-blinded, randomized clinical trial was conducted among adult outpatients with early-onset chronic depression who were not taking antidepressant medication. Patients were recruited between March 5, 2010, and October 16, 2012; the last patient finished treatment on October 14, 2013. Data analysis was conducted from March 5, 2014, to October 27, 2016. INTERVENTIONS: The treatment included 24 sessions of CBASP or SP for 20 weeks in the acute phase, followed by 8 continuation sessions during the next 28 weeks. MAIN OUTCOMES AND MEASURES: The primary outcome was symptom severity after 20 weeks (blinded observer ratings) as assessed by the 24-item Hamilton Rating Scale for Depression (HRSD-24). Secondary outcomes were rates of response (reduction in HRSD-24 score of ≥50% from baseline) and remission (HRSD-24 score ≤8), as well as self-assessed ratings of depression, global functioning, and quality of life. RESULTS: Among 622 patients assessed for eligibility, 268 were randomized: 137 to CBASP (96 women [70.1%] and 41 men [29.9%]; mean [SD] age, 44.7 [12.1] years) and 131 to SP (81 women [61.8%] and 50 men [38.2%]; mean [SD] age, 45.2 [11.6] years). The mean (SD) baseline HRSD-24 scores of 27.15 (5.49) in the CBASP group and 27.05 (5.74) in the SP group improved to 17.19 (10.01) and 20.39 (9.65), respectively, after 20 weeks, with a significant adjusted mean difference of -2.51 (95% CI, -4.16 to -0.86; P = .003) and a Cohen d of 0.31 in favor of CBASP. After 48 weeks, the HRSD-24 mean (SD) scores were 14.00 (9.72) for CBASP and 16.49 (9.96) for SP, with an adjusted difference of -3.13 (95% CI, -5.01 to -1.25; P = .001) and a Cohen d of 0.39. Patients undergoing CBASP were more likely to reach response (48 of 124 [38.7%] vs 27 of 111 [24.3%]; adjusted odds ratio, 2.02; 95% CI, 1.09 to 3.73; P = .03) or remission (27 of 124 [21.8%] vs 14 of 111 [12.6%]; adjusted odds ratio, 3.55; 95% CI, 1.61 to 7.85; P = .002) after 20 weeks. Patients undergoing CBASP showed significant advantages in most other secondary outcomes. CONCLUSIONS AND RELEVANCE: Highly structured specific psychotherapy was moderately more effective than nonspecific therapy in outpatients with early-onset chronic depression who were not taking antidepressant medication. Adding an extended phase to acute psychotherapy seems promising in this population. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00970437.
