Behavioral models of binge-type eating

Purpose: To describe and evaluate behavioral models of binge-type eating. Data identification: Studies were identified using Medline and hand searches of bibliographies of identified articles. Study selection: Isomorphic studies were selected that were judged to have some measure of construct validity. Data extraction: Face and construct validity were assessed, as well as simplicity and cost of use. Results of data synthesis: Several different models of binge-type eating exist, each with different strengths of validity and use. These include models using sham feeding, restriction/refeeding cycles and/or stress, limited access (LA) to optional foods, and eating induced by operant schedules of behavior. Conclusions: We concur with Harry Harlow, who was quoted by Gerry Smith as saying: "You'd be crazy to use animal models, but you'd also be crazy not to use them."
