This article describes the construction and preliminary validation of a new scale of weight locus of control, the Dieting Beliefs Scale. The 156-item scale demonstrated moderate internal consistency and high test-retest reliability in a sample of undergraduate women. Principal-components analysis suggested three factors. The three factors were interpretable and had distinct relations with a variety of weight-related and psychological variables. The results suggest that weight locus of control is a multidimensional construct, and they provide a possible explanation for the inconsistent findings concerning the relation between weight locus of control and dieting success. Implications for the study of dieting relapse and for the construction of treatment programs are discussed.
本文描述了一种新的体重控制点量表——节食信念量表的构建及初步验证。在本科女生样本中，这个包含156个条目的量表显示出中等程度的内部一致性和较高的重测信度。主成分分析表明存在三个因素。这三个因素具有可解释性，并且与各种体重相关及心理变量有着不同的关系。研究结果表明，体重控制点是一个多维结构，它们为体重控制点与节食成功之间关系的不一致研究结果提供了一种可能的解释。文中还讨论了这些结果对节食复发研究及治疗方案构建的启示。
