Development and Validation of the French-Canadian Chronic Pain Self-Efficacy Scale
BACKGROUND: Perceived self-efficacy is a non-negligible outcome when measuring the impact of self-management interventions for chronic pain patients. However, no validated, chronic pain-specific self-efficacy scales exist for studies conducted with French-speaking populations.OBJECTIVES: To establish the validity of the use of the French-Canadian Chronic Pain Self-efficacy Scale (FC-CPSES) among chronic pain patients.METHODS: The Chronic Disease Self-Efficacy Scale is a validated 33-item self-administered questionnaire that measures perceived self-efficacy to perform self-management behaviours, manage chronic disease in general and achieve outcomes (a six-item version is also available). This scale was adapted to the context of chronic pain patients following cross-cultural adaptation guidelines. The FC-CPSES was administered to 109 fibromyalgia and 34 chronic low back pain patients (n=143) who participated in an evidence-based self-management intervention (the PASSAGE program) offered in 10 health care centres across the province of Quebec. Cronbach’s alpha coefficients (α) were calculated to determine the internal consistency of the 33- and six-item versions of the FC-CPSES. With regard to convergent construct validity, the association between the FC-CPSES baseline scores and related clinical outcomes was examined. With regard to the scale’s sensitivity to change, pre- and postintervention FC-CPSES scores were compared.RESULTS: Internal consistency was high for both versions of the FC-CPSES (α=0.86 to α=0.96). Higher self-efficacy was significantly associated with higher mental health-related quality of life and lower pain intensity and catastrophizing (P<0.05), supporting convergent validity of the scale. There was a statistically significant increase in FC-CPSES scores between pre- and postintervention measures for both versions of the FC-CPSES (P<0.003), which supports their sensitivity to clinical change during an intervention.CONCLUSIONS: These data suggest that both versions of the FC-CPSES are reliable and valid for the measurement of pain management self-efficacy among chronic pain patients.
