Personal investment predictors of life satisfaction among physically active middle-aged and older adults.

The purpose of this study was to determine the relationship between the social psychological components of personal investment and life satisfaction among 85 middle-aged and older men and women participating in a structured exercise program. Specifically, we examined the degree to which personal incentives for exercise, perceptions of a sense of self, and the congruency between the exercise program and the participants' goals, predicted life satisfaction. Multiple regression analyses revealed that the social psychological variables reflecting personal investment accounted for 52% of the variance for life satisfaction in physically active middle-aged and older adults. The personal investment theory is supported as a framework for investigating psycho-social predictors of situational outcomes such as life satisfaction.
