Self-Directed Exercise Program for Adults With Arthritis

The purpose of this study is to examine the effectiveness and safety of a self-directed physical activity program relative to a self-directed dietary program in adults with arthritis. A process evaluation will also be conducted to examine program reach, participation/dose, fidelity, and participant compatibility/satisfaction.

Physical activity is a critical component of arthritis disease management. It also reduces the risk for other chronic comorbid conditions in people with arthritis. Yet, most adults with arthritis are not sufficiently active at the level needed to achieve benefits. Existing group-based arthritis exercise programs reach only a very small percentage of the population. The overall purpose of this study is to test a self-directed and low-cost multicomponent physical activity program for people with arthritis on outcomes including symptoms of arthritis, lower body strength, functional aerobic capacity, flexibility, physical activity, arthritis self-efficacy and disability, upper body strength, balance, gait, and depressive symptoms. The second primary aim is to evaluate the safety of the physical activity program. The third primary aim is to conduct a process evaluation to examine program reach, participation/dose, fidelity, and participant compatibility/satisfaction. Adults aged 18 years and older with arthritis will be recruited from the midlands area of South Carolina. After completion of a baseline visit, participants will be randomized in equal numbers to the 12-week physical activity program (First Step to Active Health®) or the 12-week attention-control group (Steps to Healthy Eating). The attention control intervention will have the same "look and feel" as the physical activity intervention and will require similar activities such as self-monitoring of behavior. Follow-up measurements will take place post-program (12-weeks) and 6 months post-program (i.e., 9 months post-randomization). If First Step to Active Health® is shown to be effective, it could be widely disseminated for a very low cost, thus having the potential to make a tremendous public health impact on the burden of arthritis.
