OBJECTIVE: To examine the hypothesis that change in pain self-efficacy is associated with observed and self-reported activity, pain intensity, catastrophizing, and quality of life after multi-disciplinary rehabilitation of fibromyalgia patients.

DESIGN: In-depth analyses of secondary outcomes of a randomized-controlled trial.

SUBJECTS: Women (N = 187) with fibromyalgia.

METHODS: Outcomes were Pain Self-Efficacy, Assessment of Motor and Process Skills (AMPS), SF-36 Physical Function (SF-36-PF), pain intensity, and SF-36 Mental Composite Score (SF-36-MCS) to assess quality of life and pain catastrophizing. Individual and group associations between outcomes were examined.

RESULTS: Individual changes in pain self-efficacy were not associated with changes in observed activity: AMPS motor (rs = 0.08, p = 0.27) and process (rs = 0.12, p = 0.11), not even in those patients with a clinically relevant improvement in observed functioning (38.5%), and only weakly or moderatly with changes in SF-36-PF; (rs = 0.31, p < 0.0001), SF-36-MSC; (rs = 0.41, p < 0.0001), and pain catastrophizing (rs = -0.31, p < 0.0001).

CONCLUSION: The main hypothesis was falsified, as there was no association between pain self-efficacy and actual performance of activity. The relation to functioning may be limited to perceived, cognitive-emotional aspects, as indicated by the weak to moderate correlations to the self-reported measures. Implications for Rehabilitation Improvement in observed activity post multi-disciplinary rehabilitation was not associated with change in pain self-efficacy. Patients performed better after rehabilitation, but did not perceive to have improved their capacity. The relationship between pain self-efficacy and functioning may be limited to cognitive-emotional aspects rather than actual activity. Both observational and self-reported measures should be included in evaluating outcomes of rehabilitation for patients with fibromyalgia.
