The aim of this study was to analyse the factorial structure of a brief measure of emotional intelligence in adults (EQ-i-M20) in a sample of 332 college students from Lima City, aged between 18 and 56 years (M=23.98, SD=5.497). After assessing three measurement models; a five-factor oblicuous model, bifactor model, and unidimensional model, it is concluded that the oblicuous presents the best model fit. Similarly, correlations with external criteria shown theoretically expected results. Reliability analysis evidences satisfactory levels, both at the observed scores and latent trait. The results obtained in the study confirm that EQ-i-M20 presents a well-defined five-factor structure. Finally, the results and possible consequences are discussed.
