Age differences in motivational orientation toward physical activity: an application of social-cognitive theory.
According to social-cognitive theory, an individual's motivation to engage in physical activity is based on three postulates: self-efficacy, outcome expectations, and self-evaluated satisfaction or dissatisfaction. The purpose of the present study was to examine age, gender, level of education, and level of activity in relation to those postulates in 2,298 Australians aged between 18 and 78. The authors conducted regression analyses for self-efficacy and for outcome expectations as dependent variables; age, gender, education level, and level of physical activity served as independent variables. Chi-square analyses assessed differences in the health incentive to exercise, the perceived level of activity, and the perceived level of fitness. Results indicated significant age differences on all variables. The older individual felt lower self-efficacy in relation to physical activity and expected fewer benefits from participating in physical activity. However, older individuals who engaged in physical activity rated themselves as more active and fit than nonexercisers of their same age and gender. Physical activity and level of education were positively correlated with self-efficacy, and men were more efficacious than women were. The implications are that interventions aimed at increasing participation in physical activity should take into consideration differences in incentives.
