A Scenario-Based Dieting Self-Efficacy Scale: The DIET-SE
Stich, Christine; Knauper, Barbel; Tint, Ami
Assessment, v16 n1 p16-30 2009
The article discusses a scenario-based dieting self-efficacy scale, the DIET-SE, developed from dieter's inventory of eating temptations (DIET). The DIET-SE consists of items that describe scenarios of eating temptations for a range of dieting situations, including high-caloric food temptations. Four studies assessed the psychometric properties of the 11-item DIET-SE. Exploratory factor analysis (N = 392) and confirmatory factors analysis (N = 124) revealed three internally consistent and reliable factors representing challenges to adhere to a diet (high-caloric food temptations [HCF], social and internal factors [SIF], negative emotional events [NEE]). Convergent validity is established with other measures of dieting self-efficacy, as well as measures of eating disinhibition, susceptibility to hunger, and weight loss competency. Criterion-related validity is provided through the assessment of goal adherence, and predictive validity is established for dieters' actual food intake (N = 68). The DIET-SE represents a short, reliable, and valid scenario-based measure of dieting self-efficacy. (Contains 3 tables and 1 note.)
