Guided self-determination in treatment of chronic pain - a randomized, controlled trial

OBJECTIVES: To test whether Guided Self-Determination (GSD) used in chronic pain management could improve the health-related quality of life, patient activation and sense of coherence (SoC) as a measurement of life skills in patients with chronic pain. The method has been shown to be effective in other chronic conditions, but has not been tested in chronic pain.

METHODS: A three-site randomised, controlled trial at three major multidisciplinary pain centres in Denmark. 200 patients were included and randomised. In the intervention period, both groups had regular visits to the pain centre with both doctors and nurses. The intervention group additionally received the GSD intervention with weekly sessions for eight weeks. Data were collected from February 2013 to July 2016 and consisted of three questionnaires answered before and after the 8-week intervention period, and after six months. The primary outcome was self-reported health related quality of life. Secondary outcomes included self-reported activation and SoC.

RESULTS: We found no clinically relevant difference between the groups for health-related quality of life, patient activation or SoC at either baseline, at three months or at six months. We also analysed data for trends over time using mixed model analysis, and this did not show any significant differences between groups.

CONCLUSIONS: GSD did not improve health-related quality of life, patient activation or SoC when administered to patients with chronic pain treated in a multidisciplinary pain centre. New research is recommended using a combination of self-reported and objective measures and longer follow-up.
