Abstract
The enactment of relatively easy-to-implement and relatively difficult-to-implement goal intentions was investigated in a field study of body weight maintenance for 141 university students. Three appraisal processes were examined as mechanisms for implementing intentions: self-efficacy, outcome expectancy, and affect towards means. The results showed that goal-directed dieting behaviours for men and women and goal-directed exercising/sport activities for men were influenced by the appraisals in a linear compensatory manner, and goal-directed exercising/sport activities for women were influenced by the appraisals via a three-way interaction. Self-efficacy, in particular, was a strong, pervasive determinant of both dieting and exercising/sport activities for men and women.
