Abstract

This article discusses the validation of the Oros’ Child Perfectionism Scale (EPI) in a Peruvian child population. A total of 1084 children aged 7 to 12 years (M = 9.75, SD = 1.23) from seven private and public educational institutions participated. Exploratory Factor Analysis revealed an oblique two-dimensional scale (Reaction to failure and Self-orders); however, three items had a load <. 30. The Confirmatory Factor Analysis corroborated the bidimensional oblique structure with the exception of correlated errors. Reliability was estimated using the Omega coefficient (ω = .810). It is concluded that the EPI has evidence of validity and reliability of the scores.
