The coexistence of diverse cultures in our society indicates the need to examine the factors related to the success of multicultural interactions. The study aims were to examine the psychometric characteristics of the Spanish version of the Multicultural Personality Questionnaire short form (MPQ-SF40), in a convenience sample of 392 university students. Then, the effect of sex and age was assessed, and finally, the levels and percentiles of multicultural personality were measured. The scale's validity was assessed with exploratory and confirmatory factor analysis (EFA and CFA). Reliability was evaluated with Cronbach's alpha, composite reliability (CR), and average variance extracted (AVE). The final structure of the MPQ-SF40 consisted of 18 items grouped into five factors that present adequate psychometric properties. Sex-specific differences in MPQ-SF40 were statistically significant for factor 1, cultural empathy, and for factor 5, flexibility; women showed greater values. When age was analyzed, significant low correlations were obtained. The students showed medium to high levels of multicultural personality. The highest levels correspond to the personality factors of cultural empathy and open-mindedness. The use of the Spanish version of the MPQ-SF40 seems justified to determine students' multicultural personality traits, developing intervention programs to improve social support and the interpersonal relations between students.
