A new measure of weight locus of control: the Dieting Beliefs Scale.

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.
