An Evaluation of the Potential Role of the Physician in Influencing Community Exercise Behavior

Abstract

The potential influence of physicians upon the exercise behavior of individuals has been examined. Key questions explored were a) whether people believed that their personal physician thought that they should exercise, and b) the level of motivation to comply with these perceived expectations. Subjects were drawn from four independent populations: 1) parents of junior high school students (N = 479); 2) university employees (N = 190); 3) lower-limb disabled adults (N = 62); and 4) pregnant women (N = 68). Questionnaire-based physical activity scores were transformed into Z-scores and the data sets for activity and beliefs were pooled. Multiple regression models were developed for each individual data set and for the combined data. The proportion of the variance in reported physical activity explained by the normative belief regarding the physician and the level of motivation to comply with the perceived physician's expectations was very low (adjusted R2 = 0.026 for the combined data sets). In general, healthy adults thought that their personal physician wanted them to exercise and were motivated to comply with such advice. In contrast, disabled adults saw their personal physician as opposed to exercise which they were motivated to undertake. These findings are discussed in terms of the importance of social norms as determinants of exercise behavior and the position that physicians should adopt when seeking to enhance exercise behavior.
