title: Mediators between perfectionism and eating disorder psychopathology: shape and weight overvaluation and conditional goal-setting.
abstract: OBJECTIVE
  To examine mediators of the relationship between perfectionism and eating disorder (ED) psychopathology in a clinical sample.
  
  
  METHODS
  Participants were 201 women with a DSM-IV diagnosed ED consecutively referred to a specialist outpatient treatment clinic. Participants completed measures of perfectionism, ED psychopathology, shape and weight overvaluation, and conditional goal-setting (CGS).
  
  
  RESULTS
  Evaluation of a multivariate mediator model using Baron and Kenny's (1986) four-step mediation methodology showed that shape and weight overvaluation and CGS significantly and uniquely mediated the relation between self-oriented perfectionism (SOP) and restraint, eating concern, shape concern, and weight concern. The mediator model furthered the proportion of explained variance in outcomes beyond the direct effects model by 28-49%.
  
  
  CONCLUSIONS
  The findings support the conclusion that the relationship between SOP and ED psychopathology in women with a clinically diagnosed ED is mediated by shape and weight overvaluation and CGS.
