Self-Control and the Self-Regulation of Dieting Decisions: The Role of Prefactual Attitudes,Subjective Norms,and Resistance to Temptation

This article investigates cognitive and motivational decision processes in the pursuit of dieting goals and implements the theory of trying in a field study. The theory of trying is an extension of the theory of planned behavior and investigates the effects on intentions of (a) 3 prefactual attitudes (attitudes toward success, failure, and the process of goal striving), (b) subjective norms, and (c) perceived behavioral control (i.e., resistance to temptation). Dieting decisions of 609 adult women were studied. Perceived behavioral control in the form of resistance to temptation was found to interact with subjective norms to influence intentions, and the 3 forms of prefactual attitudes had additive effects on intentions.
