Factorial Validity and Factorial Invariance Across Gender of the Frost Multidimensional Perfectionism Scale-Chinese version in Undergraduates
Objective This study was aimed to examine the factor structure and factorial invariance across gender of the Frost Multidimensional Perfectionism Scale-Chinese version (FMPS-CV). Methods The FMPS-CV was completed by 2451 undergraduates. Confirmatory factor analyses (CFA) were performed to verify its factorial validity, and Multigroup CFA were performed to examine its factorial invariance across gender. Gender differences were compared on scores of FMPS-CV. The internal consistency and test-retest reliability were also detected. Clinical characteristics were compared between adaptive and maladaptive perfectionists categorized by positive and negative scores of FMPS-CV. Results CFA supported the six-factor structure of FMPS-CV, and Multigroup CFA evidenced its factorial invariance across gender. No significant gender differences were found. The adaptive perfectionists scored significantly lower on clinical variables than maladaptive perfectionists. Moreover, the reliability indicators met the standards. Conclusions The good psychometrics properties of FMPS-CV supported it could be used to assess perfectionism in Chinese young adults.
