Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The treatment protocol consists of 10 weekly sessions of 90 minutes within three months. Every session lasts 90 minutes each. In the initial sessions, the predominant physical and psychological problems as well as problems of the patient’s current life situation are discussed. Furthermore, psychoeducation is delivered and an individual model of the patient’s current complaints and possible ways to recovery is developed. In sessions three through nine, therapist and patient focus on the individual primary pain. Different relaxation strategies are introduced and trained with the help of CBT-BF. In addition, patients receive daily homework to exercise progressive muscle relaxation. In session nine, pain-related problems such as dysfunctional cognitions and behaviour, or inactivity are modified using standard CBT techniques. In session ten, the learned methods and strategies for coping with chronic pain are reviewed and evaluated regarding their use in future pain situations. Farewell at termination of treatment is included.
