Análise Fatorial Confirmatória da Versão Portuguesa da Escala Multidimensional de Perfecionismo de Frost

Abstract

This study aimed to analyse the psychometric properties and dimensionality of the Portuguese version of the Multidimensional Scale of Frost Perfectionism (FMPS) using the confirmatory factor analysis. The sample consisted of 832 high school and college students (65.0% female) with a mean age of 19.5. The adjustment indexes of confirmatory factor analysis permitted to consider the multidimensional model of six factors the best representation of the data, replicating the original solution. The results showed good reliability and appropriate validity. The internal consistency of the scale presented satisfactory coefficients (Cronbach's alpha=.853). The test-retest method suggested a good temporal stability of the scale (r=.779). Globally the FMPS is a reliable and validated instrument for the study of perfectionism in Portugal.
