Behavioral models of binge-type eating.
OBJECTIVE
To describe and evaluate behavioral models of binge-type eating.


METHODS
Studies were identified using Medline and hand searches of bibliographies of identified articles.


METHODS
Isomorphic studies were selected that were judged to have some measure of construct validity.


METHODS
Face and construct validity were assessed, as well as simplicity and cost of use.


RESULTS
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."
