Alternative methods of classifying eating disorders: Models incorporating comorbid psychopathology and associated features

► Categorical descriptive approaches to psychiatric classification have limitations. ► In the eating disorders (EDs), several alternative nosologies have been described. ► We review alternative models that incorporate comorbid psychopathology. ► Impulsivity, compulsivity, distress, and avoidance versus risk were common themes. ► Comorbidity-based ED classes may promote neurobiologically-informed research.
