Factor Structure and Longitudinal Measurement Invariance of the Frost Multidimensional Perfectionism Scale-Brief on a Filipino Sample

Abstract

ABSTRACT The Frost Multidimensional Perfectionism Scale or FMPS is one of the first empirically validated measures of perfectionism. Cultural nuances demand that the efficiency of a short version of this scale, FMPS – Brief, be tested on an Asian sample. Given the wealth of studies that consistently linked perfectionism to academic achievement, research on the utility of this brief instrument especially with students from a collectivist background is needed. Confirmatory factor analysis of data from a sample of Filipino university students (N = 306) revealed that FMPS-Brief is a reliable and valid measure that can be used in an academic context. Aside from exhibiting the two-factor structure of perfectionism, the scale also displayed good internal consistency and convergent validity with another short version of a commonly used perfectionism measure, the Hewitt and Flett Multidimensional Perfectionism Scale. There was also evidence for the measurement invariance of FMPS-Brief across three time points. The brief scale can be used whenever the need for a short but psychometrically sound instrument for perfectionism arises.
