Abstract Background Physical activity has been consistently associated with enhanced quality of life QOL in older adults. However the nature of this relationship is not fully understood. In this study of community dwelling older adults we examined the proposition that physical activity influences global QOL through self-efficacy and health-status. Methods Participants N 321 M age 63.8 completed measures of physical activity selfefficacy global QOL physical self worth and disability limitations. Data were analyzed using covariance modeling to test the fit of the hypothesized model. Results Analyses indicated direct effects of a latent physical activity variable on self-efficacy but not disability limitations or physical self-worth direct effects of self-efficacy on disability limitations and physical self worth but not QOL and direct effects of disability limitations and physical selfworth on QOL. Conclusion Our findings support the role of self-efficacy in the relationship between physical activity and QOL as well as an expanded QOL model .
