Abstract
Objectives
Most research exploring the relationship between cognitive factors (catastrophizing and self-efficacy beliefs) and levels of pain, disability and fatigue in patients with chronic widespread pain has been performed in multidisciplinary environments. It is less clear whether these associations are valid in other clinical environments. This study therefore aimed to establish whether changes in cognitive factors were related to changes in pain, disability and fatigue among patients treated in a physiotherapy-led symptom management programme.
Design
A longitudinal pre–post treatment study. Regression analyses were performed with change in pain, disability, physical and mental fatigue as the dependent measures. Demographics, change in pain and fatigue (when not dependent variables) and cognitive factors were entered as independent variables. β values were calculated for the final model.
Setting
Two out-patient physiotherapy departments in Manchester, UK.
Participants
Fifty patients with persistent widespread pain.
Intervention
A physiotherapist-led symptom management programme.
Main outcome measures
Disability (Fibromyalgia Impact Questionnaire), Pain (Numeric Pain Rating Scale and Fatigue (Chalder Fatigue Scale)
Results
Significant changes in disability, fatigue and cognitive factors were observed after treatment. Changes in self-efficacy beliefs (β = −0.38, P < 0.05) and catastrophizing (β = 0.41, P < 0.05) were significantly related to reductions in disability. There was no significant relationship between change in the cognitive variables and change in pain or fatigue.
Conclusions
Self-efficacy beliefs and catastrophizing were important determinants of change in disability, but not pain or fatigue among patients with chronic widespread pain attending physiotherapy. Cognitively-informed physiotherapy appeared to be effective in reducing disability and fatigue and modifying cognitive factors. Such interventions may offer an effective treatment option for patients with chronic widespread pain and future randomised controlled trials are required to fully assess this.
