Association of Self-Efficacy and Outcome Expectations with Physical Activity in Adults with Arthritis

الملخص EN

Background and Purpose.

The purpose of this study is to determine whether higher baseline levels of (a) self-efficacy for physical activity, (b) self-efficacy for arthritis self-management, and (c) outcome expectations for exercise are associated with higher physical activity levels following an exercise intervention for adults with arthritis.

Methods.

A secondary analysis of the intervention cohort (n=130) within a randomized controlled trial of the People with Arthritis Can Exercise program was performed.

Multiple linear regression evaluated the relationship between physical activity at a time point three months after the completion of an exercise intervention and three main explanatory variables.

Results.

After controlling for baseline physical activity, neither self-efficacy for arthritis self-management nor outcome expectations for exercise related to three-month physical activity levels.

There was a relationship between three-month physical activity and self-efficacy for physical activity.

Conclusions.

Future research is needed to evaluate the ability of self-efficacy-enhancing programs to increase physical activity in adults with arthritis.
