Objective: To clarify the contribution of subjective norm to exercise intention and behavior by considering the influence of descriptive as well as injunctive social norms related to family and friends. Methods: A sample of 530 college students completed a questionnaire that assessed descriptive and injunctive social norms related to family and to friends, perceived behavioral control, attitude, intention, and leisure-time exercise. Results: Friend descriptive social norm was a significant predictor of both intention (p<.05) and leisure-time exercise (p<.001). Conclusion: Descriptive norms should be incorporated into tests of the theory of planned behavior in the exercise domain.
