The Attuned Representation Model of eating-disorder etiology and symptom maintenance is a comprehensive model that can effectively guide prevention and treatment efforts by addressing individual, cultural, and interactive issues. The model integrates the risk factors related to the onset of eating-disordered behaviors (i.e., biological, psychological, and social) as well as addresses ongoing systemic discordance that plays a significant role in the risk, etiology, and maintenance of eating disorders. To clarify the structure of the model, it is explicated in terms of its fit with the current state of empirical etiological research. After the model is detailed, it is described within the context of the role of the school psychologist in the prevention of eating disorders. Finally, implications for future research are briefly described. (Contains 2 figures.)
