Dspecific NERVOSA is a disorder identified by specific symptom constellations that most likely emerge from a complex integration of physiological, psychological, and environmental influences. In the search for risk factors from these influences for bulimia nervosa, the authors of the 3 articles about bulimia nervosa published in this issue have implicitly conceptualized a model of the development of bulimia nervosa. This model, which was initially proposed by Lucas1 and later expanded by Ploog2 and by myself,3 proposes that bulimia nervosa develops after the stress of dieting. This dieting experience is influenced by antecedent conditions that include genetic and physiological vulnerability, psychological predispositions that are often affected by the family, and societal influences. It is notable to remember that the salient feature of bulimia nervosa is disturbed eating behavior.
