A test of the factor structure equivalence of the 50-item IPIP Five-factor model measure across gender and ethnic groups.
Personality is frequently assessed in research and applied settings, in part due to evidence that scores on measures of the Five-factor model (FFM) of personality show predictive validity for a variety of outcomes. Although researchers are increasingly using the International Personality Item Pool (IPIP; Goldberg, 1999; International Personality Item Pool, 2007b) FFM measures, investigations of the psychometric properties of these measures are unfortunately sparse. The purpose of this study was to examine the factor structure equivalence of the 50-item IPIP FFM measure across gender and ethnic groups (i.e., Whites, Latinos, Asian Americans) using multigroup confirmatory factor analysis. Results from a sample of 1,727 college students generally support the invariance of the factor structure across groups, although there was some evidence of differences across gender and ethnic groups for model parameters. We discuss these findings and their implications.
