Moderating effects of physical self-appraisal on relations of weight with energy changes for obese women initiating a supported exercise and nutrition information program.

Significant linear bivariate correlations were found between changes in ratings of Vigor and Fatigue, and weight change over 24 weeks (rs = -.34 and .46, respectively) for 48 obese women who had initiated a supported physical activity and nutrition information program. However, after controlling for changes in Body Areas Satisfaction scale scores, the correlations decreased and were not significant. After controlling for changes in Physical Self-concept scale scores, correlations for changes in weight and Vigor scores were not significant. When changes in Body Areas Satisfaction and Physical Self-concept were simultaneously entered into separate multiple regression equations along with changes in the mood factors, significant portions of the variance in weight change (R(2)s= .36 and .29, respectively) were accounted for. Results suggested that perceptions of improvement in one's body, physical self-concept, and energy may be important predictors of weight loss in obese women and have implications for both health behavior theory and weight management treatments.
