[CBASP as an Inpatient Concept for Treatment-Resistant Chronic Depression: A Pilot Study of the Relationship between Adverse Effects and Treatment Outcome]. / CBASP als stationäres Behandlungskonzept der therapieresistenten chronischen Depression: Eine Pilotstudie zum Zusammenhang von Nebenwirkungen und Therapieerfolg.

BACKGROUND: Inpatient psychotherapy might trigger adverse effects among others due to short but intensive treatment. Thus, in this pilot study, certain adverse effects of the multidisciplinary inpatient Cognitive Behavioral Analysis System of Psychotherapy (CBASP) for treatment-resistant chronically depressed patients as well as their relationship to treatment outcome (response-, remission-, and relapse-rates) are examined. MATERIAL AND METHODS: 50 patients with treatment-resistant and chronic depression completed the structured 12-weeks inpatient treatment program. Adverse effects were assessed by 1) deterioration of depressive symptoms (measured by the Hamilton Depression Rating Scale, HDRS) at discharge and 2) a self-report questionnaire measuring Adverse Effects of Inpatient Psychotherapy (ADEFIP), which were filled out 6 to 12 months after discharge by the patients. RESULTS: After 12 weeks of treatment, 84% could be classified as responder, of whom 44% fulfilled the remission criterion. 16% were Non-Responder. According to HDRS, none of the patients showed objective deterioration of the depressive symptoms. Six months after discharge, 40% of the responders suffered from relapse. Concerning the ADEFIP, 66% of the patients reported transient deterioration of symptoms. These patients were less likely to achieve remission. Over 50% reported interpersonal conflicts with treatment team members or other patients without any relation to outcome. Finally, more than half of the patients reported significant changes in social relationships after discharge. These patients were less likely to relapse. Overall, 94% of the patients reported at least one of the in this study assessed adverse effects. CONCLUSIONS: Despite some limitations, this pilot study suggests that the CBASP inpatient program could indeed cause adverse effects. However, only subjective transient deterioration appeared to have a negative impact on the individual treatment outcome in the short-term. Results encourage further research concerning adverse treatment effects in the context of short- and long-term treatment outcome investigating how relevant adverse effects are.

Sensitivity to detect change and the correlation of clinical factors with the Hamilton Depression Rating Scale and the Beck Depression Inventory in depressed inpatients.

Discrepancies between scores on the Hamilton Depression Rating Scale (HAMD) and the Beck Depression Inventory (BDI), as well as differences regarding their sensitivity to detect change, have been reported. This study investigates discrepancies and their potential prediction on the basis of demographic, personality, and clinical factors in depressed inpatients and analyzes the sensitivity to change. The HAMD and the BDI were administered to 105 inpatients with major depressive disorder randomized to 5 weeks of either interpersonal psychotherapy or clinical management. Personality was assessed with the NEO Five-Factor Inventory. Low extraversion and high neuroticism were associated with relatively higher endorsement of depressive symptoms on the BDI compared with the HAMD. The HAMD presented a greater reduction of symptom scores than the BDI. Patients with high BDI scores, high HAMD scores or both revealed the greatest change, possibly due to a statistical effect of regression to the mean. Restricted by sample size, analyses were not differentiated by treatment condition. Regression to the mean cannot be tested directly, but it might be considered as a possible explanation. The HAMD and the BDI should be regarded as two complementary rather than redundant or competing instruments as the discrepancy is associated with personality characteristics. Attributing large effect sizes solely to effective treatment and a sensitive measure may be misleading.
