This study examined the reliability of the Spanish version of the MSCEIT, with a sample of 946 college and high school students (426 males, 520 females) ranging from 16 to 58 years old. After the translation and back-translation process, the objectives of this study were: 1) to examine the reliability of the Spanish version of the MSCEIT v.2.0 at the total scale, area, branch and subscale levels; 2) to analyze the correlations between the methods of scoring in the Spanish version of the MSCEIT v.2.0 at the total scale, area, branch and subscale levels; 3) to examine possible gender differences on MSCEIT scores; and 4) to examine the relationship between age and MSCEIT scores. These analyses revealed good reliability and internal consistency for the Spanish version of the MSCEIT; a high level of convergence between scoring methods; and higher scores obtained by women on overall scale and branches scores than scores obtained by men. A positive correlation between the scores on MSCEIT and age was found. Finally, these results are discussed in light of the limitations of the present study, the implications of the use of this new instrument, and the need for future research on emotional intelligence.
