Treatment of Depression With Mindfulness, Acceptance and Commitment

In this study, a randomized trial is conducted in which the participants are allocated to two different care services (MAC‐CBT® vs. progressive muscle relaxation). Participants are patients with depression who have been made aware of the group therapy by their treating physicians or psychotherapists or who have read the advertising in waiting areas or on the investigators homepage. An extensive psychometric survey will be conducted at the start of the study in an interview session with a psychotherapist, who also judges if the participants are able to participate in a therapy group. The MAC‐CBT® group receives an eight‐session group therapy, in which the aspects of mindfulness, acceptance and commitment are taught in detail. The control group will receive an eight‐session treatment with progressive muscle relaxation. Input and output results are determined using validated survey instruments. In addition, the investigators will check the data for moderating variables (e.g. age, gender, previous treatments...).
