Differential Efficacy of Supportive-Expressive and Cognitive-Behavioral Interventions in Dependent and Self-critical Depressive Patients: A Randomized Trial.
**Abstract**
Efficacy research shows substantial between-subject variability in the efficacy of different types of behavioral and psychotherapeutic interventions for depression. Post-hoc analyses of naturalistic data suggest that pre-structured interventions are more effective for dependent depressive patients while explorative interventions are more effective for self-critical patients. This project proposes a randomized controlled trial in which these findings are tested in a mixed method experimental set-up.
