Common Factors Across the Eating Disorder Models

Abstract

The prevalence of eating disorders and disordered eating pathology in society is well-documented, and the consequences of disordered eating can often be serious including elevated mortality and suicide rates, impairments across several health dimensions, and reduced overall quality of life. Accordingly, there has been interest in identifying and understanding the putative risk factors and how they work together to inform the development of approaches and strategies for prevention and treatment. While many theo-retical risk factor models for eating disorders have been developed over the years, relatively few have led to the development and evaluation of effective interventions for disordered eating. At least ten models have resulted in evaluated interventions, and these robust models are sum-marized in Table 1. Entries relating to some of these models (i.e., dual-pathway model of bulimia nervosa, transdiagnostic maintenance model of anorexia nervosa and bulimia nervosa, and the cognitive-interpersonal maintenance model of anorexia nervosa) can be found else-where in the Encyclopedia of Feeding and Eating Disorders.
