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.
