目的：虽然自我效能在减肥中的作用越来越受到关注，但在少数民族样本中研究这种关系的研究较少。本研究的目的是确定是否自我效能减肥预测的体重变化的样本African-American women.Research Methods and Procedures：受试者是106超重或肥胖，低收入的非洲裔美国妇女参与体重管理干预，涉及个性化的每月会议与他们的初级保健医生或标准护理。在基线和6个月treatment.Results结束时，对体重减轻的体重和自我效能进行了评估：对于个性化干预的受试者，基线自我效能可预测随后的体重变化，因此，治疗前较高水平的自我效能与体重减轻较少相关。相比之下，在治疗过程中的自我效能的改善与更大的体重减轻的个性化intervention group.Discussion：结果表明高自我效能的减肥治疗前可能是不利的成功，而治疗，提高参与者的自我效能可能会导致更大的体重减轻。高治疗前自我效能可能表明过度自信或缺乏与减肥努力相关的困难的经验。而复制是必要的，我们的研究结果表明，自我效能是一个重要的变量时，考虑实施减肥干预措施。
Objective: Although self-efficacy has received increasing attention for its role in weight loss, there is less research examining this relationship in minority samples. The purpose of this study was to determine whether self-efficacy for weight loss was predictive of weight change in a sample of African-American women.Research Methods and Procedures: Subjects were 106 overweight or obese, low-income African-American women participating in a weight management intervention that involved either personalized monthly sessions with their primary care physician or standard care. Weight and self-efficacy for weight loss were assessed at baseline and at the end of the 6-month treatment.Results: For subjects in the personalized intervention, baseline self-efficacy was predictive of subsequent weight change, such that higher levels of self-efficacy before treatment were associated with less weight loss. In contrast, improvements in self-efficacy during treatment were associated with greater weight loss for the personalized intervention group.Discussion: Results suggest high self-efficacy for weight loss before treatment may be detrimental to success, whereas treatments that improve participants' self-efficacy may result in greater weight loss. High pretreatment self-efficacy may be indicative of overconfidence or lack of experience with the difficulties associated with weight loss efforts. Whereas replication is needed, our results suggest that self-efficacy is an important variable to consider when implementing weight loss interventions.
