Small to moderate effect sizes were observed regardless of whether the intervention included exercise .
OBJECTIVE To evaluate studies that used arthritis self-management education alone or with exercise to improve Arthritis Self-Efficacy Scale scores of patients with knee osteoarthritis .
BACKGROUND Increasing self-efficacy may improve patient knee osteoarthritis symptom management and function .
Coping self-efficacy as a mediator between catastrophizing and physical functioning: treatment target selection in an osteoarthritis sample
The purpose of this study was to assess the relative effects of coping self-efficacy and  catastrophizing  on physical functioning . Over a 9-month period , study ing changes in self-efficacy as possible mediator between catastrophizing changes and physical functioning changes might provide evidence for the most promising treatment target . Data came from a r and omized , longitudinal controlled trial comparing exercise , self-management and the two combined to treat 254 individuals with early knee osteoarthritis . A secondary analysis using a bootstrapped linear mixed-effects mediational model produced estimates of both the direct and indirect effects . Results indicated that self-efficacy partially mediated the effect between catastrophizing and physical functioning suggesting that self-efficacy was the more direct treatment target compared to catastrophizing . Treatments targeting both  self-efficacy and catastrophizing  may have greater impact on physical functioning compared to treatments that focus on only one
