Objective:
To assess the theory of planned behavior (TPB) and TPB with functional ability to explain intention and self-reported physical activity (PA) behavior of older adults.
Methods:
A survey was mailed to 2056 retirees from a large Midwestern university.
Results:
Structural equation modeling revealed that the TPB plus functional ability explained an additional 11% variance than the TPB alone in older adult PA and functional ability was the best predictor of PA (beta = .53, P<.05).
Conclusions:
Functional ability appears to be an important predictor of PA behavior and should be included when designing PA programs for older adults.
