title: Self-oriented and socially prescribed perfectionism in the Eating Disorder Inventory Perfectionism subscale.
abstract: OBJECTIVE
  The purpose of this study was to demonstrate the existence and the importance of the distinction between self-oriented and socially prescribed perfectionism in the Eating Disorder Inventory Perfectionism subscale (EDI-P).
  
  
  METHODS
  Trait perfectionism, measured by the EDI-P, and eating disorder symptoms, measured by the 26-item Eating Attitudes Test, were examined in 220 university students (110 women and 110 men) belonging to a campus-based fitness facility.
  
  
  RESULTS
  Confirmatory factor analysis indicated that, for both genders, the EDI-P is best represented by a multidimensional factor structure with three self-oriented perfectionism items (EDI-SOP) and three socially prescribed perfectionism items (EDI-SPP). Structural equation modeling demonstrated that, for both genders, EDI-SOP and EDI-SPP are related independently to eating disorder symptoms. Moderational analysis indicated that, for women, the impact of EDI-SOP on eating disorder symptoms is dependent on the level of EDI-SPP.
  
  
  CONCLUSIONS
  It is suggested that future research should acknowledge the empirical and theoretical implications of having EDI-SOP and EDI-SPP in the EDI-P. It is cautioned that EDI-SOP and EDI-SPP are a partial representation of an already published multidimensional model of trait perfectionism.
