The psychometric properties of the English version of the Trait Emotional Intelligence Questionnaire (TEIQue v. 1.50; Petrides, 2009) were recently investigated in Lebanon (Sanchez-Ruiz et al., International Journal of Psychology, 56(2), 304–313, 2020). We extended these findings by further examining the validity of the TEIQue in the Lebanese context through its associations with emotion regulation strategies, depression, procrastination, body image dissatisfaction (BID), and the Big Five personality traits. The results indicated that trait EI was positively correlated with cognitive reappraisal (r = .14) and negatively correlated with expressive suppression (r = − .24), highlighting distinct relationships with emotion regulation strategies as evidence of discriminant validity. Additionally, trait EI showed negative correlations with depression, procrastination, and BID, demonstrating strong criterion validity. Hierarchical regression analyses further supported the incremental validity of trait EI, with Self-control predicting procrastination, Well-being predicting BID, and both factors negatively predicting depression, even after controlling for the Big Five. These findings substantiate the validity of the English version of the TEIQue in Lebanon and emphasize its theoretical and practical relevance in predicting key psychopathological and life outcomes.
