Abstract

Eating disorders (EDs) are one of the most severe and complex mental health problems facing researchers and clinicians today. The effective prevention and treatment of these conditions is therefore of paramount importance. However, at present our treatments fall short: generally demonstrating only poor to moderate efficacy, and often completely ineffective for severe or chronic cases. A possible reason for this is that the current theories underlying these treatments are flawed. In this paper, we review and evaluate several prominent theoretical explanations associated with current frontline and promising treatments for ED. In doing so, we identify fundamental problems within the construction of current ED explanations and their implications for treatment. In response to these findings, we propose several strategies for the construction of future ED explanations which we believe have the power to ameliorate these problems and potentially help to develop more efficacious treatment downstream.
