Theoretical model testing to identify personality variables effecting preventive behaviors

To test the preventive behavior model, the impact of perceived barriers and benefits and health value orientations on two health care activities (smoking and exercise) was examined. Data from 76 subjects who had taken part in a health screening program were analyzed using regression analysis. A reduced empirical model for exercise resulted, explaining 46% of the variance. However, only one variable that accounted for 7% of the variance was significant in explaining smoking behavior. Significant personality variables in the exercise model provide clues toward understanding psychological factors that may be operating to influence an individual's participation in health care activities.
