The aim of the present study was the examination of the psychometric properties and the evaluation of the factorial composition of the Mini-IPIP five-factor model personality scale among a sample of Portuguese college students (n = 2153). Factor analysis highlighted a structure similar to the one proposed by Donnellan et al. (Psychological Assessment, 18, 192–203. doi: 10.1037/1040–35126.96.36.199, 2006), showing acceptable fits in confirmatory factor analysis. The Portuguese version of the Mini-IPIP five-factor model personality scale demonstrated good psychometric properties in terms of factor structure, internal consistency, and convergent validity. The results suggest that the Portuguese version of the Mini-IPIP five-factor model personality scale may have many potential applications in diverse psychological assessment contexts in Portugal and Portuguese speaking countries.
