Abstract: | Hypotheses are proposed about relations among "building block" components of the motivation to attain exercise goals in an organizational fitness program, as well as about health-related individual differences in those components. The hypotheses are tested in a longitudinal field study involving questionnaire, physiological, and behavioral data from 107 participants in such a program. In support of the componential hypotheses, goal attainment was a positive function of goal commitment. Goal commitment was an additive function of goal attractiveness and goal-specific self-efficacy/perceived control. In support of the individual difference hypotheses, physiological variables were associated with work- and health-related perceived barriers to goal attainment. Employees with high health risks ranged from .5 to 1.2 SDs higher in perceived barriers than employees with low risks. Evidence suggests that for goal setting to succeed as a program intervention, managers must concentrate on reducing the perceived work- and health-related barriers to exercise participation and goal attainment, especially for employees with high health risks. |
