Behavioral Activation for Depression and Habitual Rumination
Sponsor: Ragnar Pétur Ólafsson
Summary
Depressive rumination, a negative thinking style characterized by repetitive and passive thoughts about the causes, meanings, and consequences of one's feelings and distress, is often described as being a habitual response tendency that forms a vulnerability to depression. Behavioural Activation (BA) is an effective treatment for depression but little is known of mechanisms of changes during a successful treatment completion and for whom the treatment benefits the most. The main purpose of the study is to investigate whether habit-like mood-reactive rumination will change during Behavioral Activation treatment for current depression and mediates symptom changes in the treatment. Important moderators of change will also be investigated (i.e. history of early life stress and cognitive flexibility). We aim to provide individual BA treatment for up to 120 currently depressed participants (from 90 to 120 participants) in 12 treatment sessions over 11 weeks. Measures are obtained at pre-treatment, during treatment, at post-treatment and at 6 month follow up.

Behavioural Activation (BA)
Behavioural activation treatment delivered in this single arm study. Individual treatment given to all participants in 12 sessions over 11 weeks. All treatment components have been introduced by session 8 that defines minimum amount of treatment in the trial (i.e. 8 session completed). Behavioral Activation is a psychological treatment for depression focused on gradually re-engaging people with sources of reinforcement and reward in their environment by re-establish healthy patterns of activity, and replace avoidance behaviours with more adaptive behaviours.
