This study aimed to test to what extent improvements in self-appraisal and mood factors were associated with changes in body mass index (BMI; kg/m2) and waist circumference. Women with obesity (N=171) completed Physical Self-Concept, Exercise Self-Efficacy, Body Areas Satisfaction, Tension, and Depression scales, and were measured on BMI and waist circumference, at baseline and just after a 24-week supported exercise program. With the exception of Physical Self-Concept, improvements on each psychological factor were associated with significantly greater weight and waist circumference improvements. Multiple regression analyses indicated that improvement/non-improvement on the psychological factors explained a significant 9 to 11 percent of the variance in BMI change, and 13 to 20 percent of the variance in waist circumference change. Significant unique contributions to the explained variance in BMI were made by improvements in Exercise Self-Efficacy and Depression, with improvement in Tension also making significant unique contributions to the explained variance in waist circumference change. Consistent with tenets of social cognitive theory, the association of improvements in self-appraisal and mood factors with weight and waist circumference improvements was supported in obese women. Replications and extensions of this preliminary research to, ultimately, improve weight loss theory and treatment, was suggested.
本研究旨在测试自我评估和情绪因素的改善与体重指数（BMI；千克/平方米）及腰围变化之间的关联程度。肥胖女性（N = 171）在基线时以及在一项为期24周的支持性运动计划结束后，完成了身体自我概念、运动自我效能、身体部位满意度、紧张感和抑郁量表的测评，并测量了BMI和腰围。除身体自我概念外，各心理因素的改善均与体重和腰围的显著更大改善相关。多元回归分析表明，心理因素的改善/未改善解释了BMI变化中9%至11%的显著方差，以及腰围变化中13%至20%的方差。运动自我效能和抑郁的改善对BMI解释方差有显著的独特贡献，紧张感的改善对腰围变化解释方差也有显著的独特贡献。与社会认知理论的原则一致，肥胖女性中自我评估和情绪因素的改善与体重和腰围改善之间的关联得到了支持。建议对这一初步研究进行重复和扩展，最终改进减肥理论和治疗方法。
