Psychoanalytic and cognitive-behavior therapy of chronic depression : study protocol for a randomized controlled trial

Background: Despite limited effectiveness of short-term psychotherapy for chronic depression, there is a lack of trials of long-term psychotherapy. Our study is the first to determine the effectiveness of controlled long-term psychodynamic and cognitive-behavioral (CBT) treatments and to assess the effects of preferential vs. randomized assessment. Methods/design: Patients are assigned to treatment according to their preference or randomized (if they have no clear preference). Up to 80 sessions of psychodynamic or psychoanalytically oriented treatments (PAT) or up to 60 sessions of CBT are offered during the first year in the study. After the first year, PAT can be continued according to the ‘naturalistic’ usual method of treating such patients within the system of German health care (normally from 240 up to 300 sessions over two to three years). CBT therapists may extend their treatment up to 80 sessions, but focus mainly maintenance and relapse prevention. We plan to recruit a total of 240 patients (60 per arm). A total of 11 assessments are conducted throughout treatment and up to three years after initiation of treatment. The primary outcome measures are the Quick Inventory of Depressive Symptoms (QIDS, independent clinician rating) and the Beck Depression Inventory (BDI) after the first year. Discussion: We combine a naturalistic approach with randomized controlled trials(RCTs)to investigate how effectively chronic depression can be treated on an outpatient basis by the two forms of treatment reimbursed in the German healthcare system and we will determine the effects of treatment preference vs. randomization

Recovery from chronic depression and structural change : 5-year outcomes after psychoanalytic and cognitive-behavioural long-term treatments (LAC depression study)

Objective: Psychotherapy of chronic depression has remained a challenge due to limited prognosis and high rates of recurrence. We present 5-year outcome data from a multicentre trial comparing psychoanalytic (PAT) and cognitive-behavioural (CBT) long-term treatments with randomized and preferred allocations analysing symptom (N = 227) and structural change (N = 134) trajectories. Method: Self- and blinded expert ratings of depression symptoms were performed at yearly intervals using the Beck Depression Inventory-II (BDI-II) and Quick Inventory of Depressive Symptoms (QIDS-C). Blinded expert ratings of Operationalized Psychodynamic Diagnosis (OPD) and the Heidelberg Restructuring Scale (HRS) at baseline, 1, 3, and 5 years assessed structural change in a subsample. Results: Lasting and comparable symptom changes were achieved by PAT and CBT. However, compared to CBT, PAT was more successful in restructuring, a major goal of long-term psychodynamic treatments with high frequency and duration. Limitations: Due to practical reasons, the time criterion for chronic depression of an acute phase had to be defined for over 1 year in the present study, which does not correspond to the DSM-5 criterion of 2 years. Therapy duration and session frequency were not incorporated into the statistical models. Conclusion: Long-term psychotherapy helps patients with a yearlong history of depression and often multiple unsuccessful treatment attempts to achieve lasting symptom changes. Future follow-up will clarify whether restructuring promotes further sustainable improvements
