Psychometric properties of the Pride in Eating Pathology Scale in a Spanish population

Abstract

Background: In its relation to eating disorders, pride is one of the self-conscious emotions least analyzed, and requires valid and reliable instruments for its measurement. This study aimed to examine the factor structure and the psychometric properties of the Pride in Eating Pathology Scale (PEP-S), in the Spanish general population, as well as between-sex diferences in PEP-S scores. Methods: Of the 1483 participants aged 18 to 34 (M=21.99; SD=3.09), 954 were women (65.2%) and the majority were university students (78.8%). Psychometric properties of the scale were tested in a cross-sectional design using cross-validation, i.e., exploratory and confrmatory factor analysis, and estimation of invariance (sex). Results: The four-factor structure found was similar to the original scale with invariance across sex and internal consistency (ordinal alpha .99) and stability (.85). Evidence of convergent validity and diferences between sexes were found. Specifcally, women scored higher on all the factors, including the healthier sense of pride. Conclusions: The PEP-S scale is an instrument with evidence of validity and reliability in the Spanish population. Although it still has to be tested in a clinical population, it constitutes a promising instrument for the evaluation of the self-conscious emotion, pride.
