This study explored concurrent and incremental validity of three trait emotional intelligence measures: the Schutte Emotional Intelligence Scale, Multidimensional Emotional Intelligence Assessment, and Trait Emotional Intelligence Questionnaire. A total of 307 participants were drawn predominantly from community and student populations. Concurrent criterion validity of the measures varied depending on whether emotional intelligence (EI) was assessed as a lower, middle or higher level construct, with validity coefficients being larger for the former. In all cases, the Trait Emotional Intelligence Questionnaire was the superior predictor of multiple psychological criteria. At the higher level of assessment, incremental validity beyond (a) age, gender and the Big Five, and (b) the remaining two EI measures, was also superior.
