Trait emotional intelligence (EI) is a constellation of emotion-related self-perceptions located at the lower levels of personality hierarchies. This article examines the validity of the Trait Emotional Intelligence Questionnaire-Child Form and investigates its relationships with Big Five factors and cognitive ability. A total of 690 children (317 Males; M Age = 10.25 years; SD = 1.58 years) completed the TEIQue-CF, the Raven Progressive, Matrices and the Big Five Questionnaire; in addition, a subsample of 136 participants answered to Depression and Anxiety scales. Results evidenced that TEIQue-CF is a reliable measure of Trait EI that is partially determined by all of the Big Five factors but independent of cognitive ability. Trait EI predicts depression and anxiety scores over and above the five higher order personality dimensions. (Contains 3 tables.)
