- Public TitleThe added value of positive compared to traditional CBT techniques
- Scientific TitlePositive compared to traditional cognitive-behavioral therapy strategies in depression. A within-subject comparison.
- hypothesisThe aim of the current project is to investigate whether positive, strengths- and exception-focused CBT may be a useful supplement or an alternative to the traditional, problem-focused CBT approach for clinically depressed individuals. Primary outcome measures are (1) the experience of positive emotions, hope, and flourishing mental health, and (2) improvements in depressive symptoms. In a within-subject design, conventional CBT will be alternated with positive CBT in two blocks of eight sessions each (with the order of blocks counterbalanced). We predict that: Clients will report stronger improvements in mental health, life satisfaction and sense of well-being after blocks of positive compared to traditional CBT. Improvements in depressive symptoms occur at an equal rate in both CBT variants. Clients as well as therapists experience more positive emotions after positive CBT sessions and that they rate the positive CBT sessions as more satisfying than the traditional, problem-focused CBT sessions. Drop-out rates will be less in treatments that start with the positive CBT block, although the current study may be underpowered to address this last hypothesis.

- Target number of participants34
- InterventionsAll participants are offered CBT for depression according to a protocol. However, the traditional, problem-focused approach is augmented with a positive CBT approach. Next to problem inventories and analyses of dysfunctional thoughts, the therapist focusses on exceptions to problems, strengths of the client, and progress towards goals. The two approaches are organized in two separate blocks in order to disentangle the effects of the different treatment approaches. The order of treatment sessions is randomized: half of the participants start with eight sessions of positive CBT followed by eight sessions of traditional, problem-focused CBT, for the other half the order is reversed.
