Is Less More? Dosing and Sequencing Effect

The investigators want to evaluate core components from cognitive behavioral psychotherapies (CBTs) with the aim of investigating dosing and combinatory effects on conditions of anxiety and depression.

In the present study, participants will be randomly assigned to one of four groups, receiving one or both treatment components under investigation, all over the course of six sessions of treatment. 1. It is hypothesized that both component A (Cognitive Restructuring) and component B (External Attention Allocation) will be efficient in reducing symptoms of depression and anxiety when delivered separately, both when delivered over 3 and 6 sessions. The difference between components as well as between the number of sessions on primary and secondary outcomes will be explored. 2. The combinatory effects, comparing the effect of receiving Component A subsequent to Component B and vice versa will be explored. 3. The process of change in both components will be explored. 4. Group differences in participants' experience of being the recipient of the components (either individually or combination) both qualitatively (free descriptions of their experience with using them) and quantitatively (questionnaires concerning the understanding and employment) will be explored. 5. The moderating effect of baseline characteristics including baseline symptomatology, diagnoses, personality functioning, and working alliance will be explored. 6. Potential harmful effects will be explored in each group.
