Abstract

It has been experimentally shown that the population of high restrained eaters consists of two subpopulations, i.e., those with a low and those with a high susceptibility toward failure of restraint. Only those who combined high restraint with high scores on the disinhibition scale of the TFEQ (Three-Factor Eating Questionnaire) showed overeating after a preload. The aim of the present study was to assess the concurrent validity of a two-factorial classification using the Dutch Eating Behavior Questionnaire (DEBQ) scales for restraint, emotional and external eating, as well as the bulimia scale of the Eating Disorder Inventory (EDI) for locating dieters with low or high susceptibility toward failure. It was examined whether the resulting two-group classification is associated with self-reported behaviors and features of psychopathology, which are generally thought to differentiate both groups of dieters. The results indicated that the two-group classification was indeed associated with many of these behaviors and features of psychopathology. It was concluded that this classification has a good concurrent validity.
