Convergent and criterion-related validity for a brief scale of the Five-Factor model

Abstract

This study sought evidence for the validity for the Reduced Markers Scale (EMR) in a population of university students (n=175, mean age=28.5, SD=7.4). The EMR is composed of 25 items that measure and evaluate personality according to the Five-Factor Model. For convergent validity, we analyzed the correlations between the EMR and the Bateria Fatorial de Personalidade (BFP). For the criteria-related validity, regression analyses were conducted for EMR and the Positive Mental Health Scale. The results indicated high significant correlations between the EMR and BFP, except for the factor of Sociability and Openness to Experiences. Both EMR and BFP showed similar abilities to explain the external criterion, and the BFP accounted for 10% of the residual variance. The EMR proved to be suitable for evaluating personality in this sample. However, we consider there are some limitations due to the amount of information provided by the instrument.
