Abstract
OBJECTIVES: To investigate the effects on persons with chronic pain after 3 months of a group-based chronic pain self-management course compared with a drop-in, low-impact outdoor physical group activity on patient activation and a range of secondary outcomes. DESIGN: An open, pragmatic, parallel group randomised controlled trial. Analyses were performed using a two-level linear mixed model. SETTING: An easily accessible healthcare service provided by Norwegian public primary healthcare. PARTICIPANTS: A total of 121 participants with self-reported chronic pain for 3 months or more were randomised with 60 participants placed in the intervention group and 61 placed in the control group (mean age 53 years, 88% women, 63% pain for 10 years or more). INTERVENTIONS: The intervention group was offered a group-based chronic pain self-management course with 2.5-hour weekly sessions for a period of 6 weeks. The sessions consisted of education, movement exercises and emphasised group discussions. The control group was offered a low-impact outdoor group physical activity in 1-hour weekly sessions that consisted of walking and simple strength exercises for a period of 6 weeks. MAIN OUTCOMES: The primary outcome was patient activation assessed using the Patient Activation Measure. Secondary outcomes measured included assessments of pain, anxiety and depression, pain self-efficacy, sense of coherence, health-related quality of life, well-being and the 30 s chair to stand test. RESULTS: There was no effect after 3 months of the group-based chronic pain self-management course compared with the control group for the primary outcome, patient activation (estimated mean difference: -0.5, 95% CI -4.8 to 3.7, p=0.802). CONCLUSIONS: There was no support for the self-management course having a better effect after 3 months than a low-impact outdoor physical activity offered the control group.
