The concurrent validity of two measures of Emotional Intelligence (EI), one considered a trait measure, the other an ability measure, was examined by administering the Emotional Quotient Inventory: Youth Version (EQi:YV; Bar-On & Parker, 2000), the Mayer-Salovey-Caruso Emotional Intelligence Test: Youth Version (MSCEIT:YV; Mayer, Salovey, & Caruso, in press), and a sociometric measure to 102 upper elementary students in the U.S. Pearson product-moment correlation coefficients across various scores of the EI instruments ranged from -0.02 (p greater than 0.05) to 0.39 (p less than 0.01), suggesting the instruments are measuring somewhat different constructs. Scores on two sets of theoretically similar scales across instruments yielded significant correlation but others did not. Results from dependent t tests showed no significant difference between overall mean scores of the EQi:YV and MSCEIT:YV (p less than 0.05). Only the Interpersonal and General Mood scales of the EQi:YV correlate significantly with the sociometric (p less than 0.05). Implications for further research in EI are discussed.
