Emotional intelligence: a theoretical and empirical review of its first 15 years of history.

The term Emotional Intelligence (EI) was first introduced in the scientific literature in 1990. Since then, the development of models of EI and research in this field has increased substantially. In this manuscript, a theoretical and empirical review of the first 15 years of history of EI is presented. First, the broad interest on this concept is shown through qualitative and quantitative indexes. Then, current theoretical models of EI: the mental ability model; the Bar-On Model of Emotional-Social Intelligence; and Goleman's model of EI are described in depth. Finally, authors give relevant keys about future considerations for research on EI. Specifically, authors 1) propose some ideas concerning the measurement of the construct and the use of ability and self-reported measures; 2) discuss the learning, development, and training potential of EI; and 3) consider the cross-cultural validity of EI.
