By comparing exercise and health domains, the current experiment extends recent findings that within-participant analyses of attitudes and subjective norms predict behavioral intentions well (Finlay, Trafimow, & Moroi, 1999). Within-participant analyses show that health behaviors are particularly likely to be influenced by subjective norms, and those that are relatively normatively influenced are intended to be performed more than those that are not. However, neither was true of exercise behaviors. Additionally, other potential predictors for exercise (e.g., indirect attitudinal measures and goal-oriented attitudes and intentions) correlated more strongly with exercise behavioral intentions than did general health attitudes and intentions.
