- Abstract
This study examined the role of perfectionism (self-oriented and socially prescribed), shape and weight overvaluation, dichotomous thinking, and conditional goal setting in eating disorder psychopathology. Perfectionism and shape and weight overvaluation have had longstanding implication in the development and maintenance of eating disorders. A leading evidence-based theory of eating disorders (Fairburn, Cooper & Shafran, 2003) outlines perfectionism as a maintaining mechanism of eating disorder psychopathology and as a proximal risk factor for the development of shape and weight overvaluation. These constructs have been linked to other cognitive processes relevant to eating disorders, specifically, dichotomous thinking and conditional goal setting. Women with DSM-IV eating disorders (N=238) were compared to women in the general community (N=248) and, as hypothesised, scores on measures of these constructs were pronounced in the clinical sample. Hierarchical regression analyses predicting eating disorder psychopathology showed that for both groups, dichotomous thinking and conditional goal setting significantly improved model fit beyond perfectionism and shape and weight overvaluation alone. Self-oriented perfectionism, but not socially prescribed perfectionism, was relevant to eating disorder psychopathology. We discuss the implications for current treatment protocols and early intervention., (Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.)
