Objective: To obtain evidence on the internal structure of a brief emotional intelligence scale in Mexican health sciences students. Method: A total of 221 students (66.1% women) from 4 health sciences degrees were evaluated with the EQ-i-M20. An exploratory structural equation modeling was carried out, with the weighted least square mean and variance (WLSMV) estimation method and geomin rotation. The reliability of the construct was evaluated using the omega coefficient. Results: The original structure of 5 factors obtained satisfactory fit indices, as well as an expected grouping of the items in their theoretical factors. Similarly, adequate reliability coefficients were obtained. Conclusion: The structure of the EQ-i-M20 is favourably replicated in Mexican university students. The practical implications of the findings are discussed.
