Abstract
Background
The study objectives were to determine (a) the effects of group-mediated cognitive–behavioral interventions on change in performance self-efficacy, satisfaction with function, and with appearance among older, overweight/obese adults in poor cardiovascular health and (b) whether self-efficacy mediated change in 400-m walk time.
Methods
This translational, randomized controlled trial of physical activity and weight loss was conducted within community Cooperative Extension Centers. Participants were randomized to three intervention arms: Physical Activity, Weight Loss + Physical Activity, or a Successful Aging education control.
Results
Across 18 months, the Weight Loss + Physical Activity intervention demonstrated greater improvements in self-efficacy, satisfaction with function, and appearance versus other trial arms. Physical Activity intervention participants also experienced significant improvements in self-efficacy and satisfaction with function versus those in Successful Aging. Self-efficacy mediated 400-m walk time at 18 months.
Conclusions
Both group-mediated cognitive–behavioral interventions yielded desirable improvements in social cognitions and preserved mobility improvements post-intervention.
