The present investigation reports on the reliability and validity of several scales derived from the Health Belief Model (HBM). Both their internal consistency and their ability to predict self-reported sport and physical activity participation among younger and older adults are examined. As an exploratory endeavor, new, internally consistent scales were developed to assess several HBM factors. Results of age-group comparisons as well as comparisons across levels of diversity in several types of self-reported physical activity suggest that the newly developed measures differentiate between individuals on the basis of age and degrees of diversity in activity.
