自我效能感是促进肥胖治疗理解的重要中介机制。本研究开发并验证了体重效能生活方式问卷（WEL），通过使用临床人群，交叉验证初始因素分析，探索自我效能的最佳拟合理论模型，并检查治疗的变化，改进了以前的研究。由此产生的20项WEL由五个情境因素组成：消极情绪，可用性，社会压力，身体不适和积极活动。一个层次模型被发现提供最佳的拟合数据。两个独立的临床治疗研究（总N = 382）的结果表明，WEL是敏感的全球分数的变化，以及一个子集的五个情境因素的分数。如果治疗方案只改变自我效能感的一部分情境维度，那么治疗方案可能是不完整的。理论和临床意义进行了讨论。
Self-efficacy is an important mediating mechanism in advancing understanding of the treatment of obesity. This study developed and validated the Weight Efficacy Life-Style Questionnaire (WEL), improving on previous studies by the use of clinical populations, cross-validation of the initial factor analysis, exploration of the best fitting theoretical model of self-efficacy, and examination of change in treatment. The resulting 20-item WEL consists of five situational factors: Negative Emotions, Availability, Social Pressure, Physical Discomfort, and Positive Activities. A hierarchical model was found to provide the best fit to the data. Results from two separate clinical treatment studies (totalN= 382) show that the WEL is sensitive to changes in global scores as well as to a subset of the five situational factor scores. Treatment programs may be incomplete if they change only a subset of the situational dimensions of self-efficacy. Theoretical and clinical implications are discussed.
