The purpose of this study is to compare the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) conducted over 16 weeks (acute and continuation treatment) with Behavioral Activation (BA; same dose and duration) in persistently depressed treatment-resistant inpatients regarding efficacy, moderators and mediators of change.
About half of all psychiatric inpatients with depression suffer from persistent depressive disorder (PDD). Given their high degree of treatment-resistance (TR), comorbidity, suicidality, and hospitalization rates, this patient group appears to be particularly difficult to treat and, from a health economic perspective, constitutes a major challenge. The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) is the only psychotherapy specifically tailored for PDD. Originally developed as an outpatient treatment by James P. McCullough, CBASP has been modified for the severely ill PDD patients with TR as a multimodal inpatient concept. Pilot studies indicate very good feasibility and promising outcome. Therefore, a randomized controlled trial is now mandatory for testing the superiority of the inpatient CBASP program vs. the evidence-based Cognitive Behavioral Therapy (CBT), the 'gold standard' in depression treatment. Behavioral Activation (BA) was chosen as the control intervention because BA, as a specific variant of CBT, is at least as effective as standard CBT in severely depressed patients while being easier to train and implement in inpatient settings. Both therapies will be applied as a treatment-phase program (10-week inpatient/ dayclinic acute treatment followed by 6-week outpatient continuation group-treatment) in combination with standardized and guideline-based pharmacotherapy. The proposed prospective, multi-center, randomized study with 396 PDD patients with TR will therefore address the primary research question: Is the CBASP program more effective than the BA program in this patient group? The primary hypothesis is that after 16 weeks of treatment, CBASP will show a significant superiority over BA in reducing depressive symptoms. In addition, the important psychotherapy research question: what works for whom and why? will be addressed.
Moderator analyses will examine whether child maltreatment and methylation of exon IV of the BDNF gene have an impact on the differential efficacy of the treatments. Regarding mediator analyses, it will be examined whether the differential efficacy of the treatments can be explained by treatment-specific changes in interpersonal problems or activity levels. A follow-up survey 48 weeks after the end of the interventions will provide valuable results regarding the long-term outcome of the treatments. Finally, the health economic potential of the interventions will be investigated through cost-benefit analyses in order to provide important information on the cost-effectiveness of implementation in routine care for health policy. Thus, the results of this study will have the potential to relieve the burden of this very serious and cost-intensive disorder while improving human health. In addition, moderator and mediator analyses may guide personalized treatment and enable therapists to more specifically address psychotherapeutic needs of individual PDD patients in the future.

Due to the nature of interventions, blinding of patients/therapists concerning the treatment program is impossible, but all assessments as well as data analysis will be blinded to treatment allocation. Notably, patients are blinded to the study hypothesis by the Informed Consent process, as patients are told in the patient information and educational discussions about the study that they will in any case receive one of two different scientifically based psychotherapy programs, although it is unclear which of the two programs is more effective, one program focuses on coping with interpersonal problems, the other on building up activities that seem important for personal life. Similarly, the members of the treatment teams of each study ward are not informed about the study hypothesis; however, they are informed that it has not yet been scientifically clarified which therapy is more effective.

| baseline, weeks 1, 2, 4, 6, 8, 10, 12, 14, 16, 64 |
| Inventory of Depressive Symptomatology, Self-Report (IDS-SR) | The IDS-SR is a self-reported measure of depressive symptoms and used to detect change in self-rated depression severity. It shows good psychometric properties. Each item is rated from 0 to 3 by the patient, and all values are added up to an overall score. Total score ranges from 0 to 78, with higher values indicating a higher depression severity. | baseline, weeks 1, 2, 4, 6, 8, 10, 12, 14, 16, 24, 32, 40, 48, 56, 64 |
| Brief Symptom Inventory (BSI) | The BSI is a multi-dimensional self-reported measure with a total of nine scales assessing the subjective impairment by physical and psychological symptoms. Each item is rated on a scale from 0 to 5 by the patient and are added up and t-transformed to three global indices: Global Severity Index, Positive Symptom Distress Index, Positive Symptom Total. T-Scores range from 0 to 100, with higher values indicating a higher subjective impairment. | baseline, weeks 1, 5, 10, 16, 64 |
| Global Assessment of Functioning (GAF) | The GAF is a diagnostic measure used to assess social, occupational and psychological functioning according to DSM-IV. The score ranges from 0 to 100 with a total of ten levels of functioning and is determined by a clinical rater. Higher scores indicate a higher level of functioning and therefore a better outcome. | baseline, weeks 1, 5, 10, 16, 64 |
| World Health Organization Quality of Life (WHOQoL-BREF) | The WHOQoL-BREF is a self-reporting measure regarding the subjective quality of life. Four broad domains of quality of life are rated by the patient on a five point scale and a mean score for each domain is calculated. Scores range between 4 and 20, with a higher score indicating a higher quality of life and therefore a better outcome. | baseline, weeks 1, 5, 10, 16, 64 |
| Response | Response (50% decrease on HDRS-24 score) | weeks 5, 10, 16, 64 |
| Remission | Remission (HDRS-24 score of 10 or less) | weeks 5, 10, 16, 64 |

| Baseline |
| Brain-derived neurotrophic factor (BDNF) | Brain-derived neurotrophic factor (BDNF) methylation as a main moderator. | Baseline |
| Inventory of Interpersonal Problems-revised (IIP-32-R) | The IIP-32-R is a self-reported questionnaire that assesses the severity of interpersonal problems on eight scales based on the two-dimensional interpersonal circumplex model as a main mediator. The items are rated on a five-point scale by the patients. A mean score is calculated, ranging from 0 to 4. A higher score indicates a higher severity of interpersonal problems and therefore a worse outcome. | Baseline, weeks 1, 2, 4, 6, 8, 10, 12, 14, 16 and 64 |
| Behavioral Activation Depression Scale (BADS) | This self-report is designed to measure weekly changes in avoidance and activation during treatment with Behavioral Activation for depression. The BADS consists of 25 questions on four subscales, each rated on a seven point scale ranging from 0 to 6. The subscales are activation, avoidance/rumination, work/school impairment, and social impairment. A higher total score represents a higher level of activation and therefore a better outcome, while a high score in the subscale social impairment indicates a higher level of impairment and therefore a worse outcome. Scores range from 0 to 150. | Baseline, weeks 1, 2, 4, 6, 8, 10, 12, 14, 16 and 64 |
