This study investigated the predictive relationship among Trait Emotional Intelligence (TEI), self-esteem, and trait anxiety within a sample of Greek native individuals (N=136), employing multiple regression analysis. The Trait Emotional Intelligence Questionnaire (TEIQue), The Spielberger State-Trait Anxiety Inventory (STAIT-5), and the Rosenberg Self-Esteem Scale were administered for data collection. Results revealed a robust positive correlation between TEI and self-esteem (r= 0.61, p<0.001), with both variables emerging as significant predictors of trait anxiety. Decreases in TEI and self-esteem corresponded to increases in trait anxiety, with the model explaining 33.5% of the variance in trait anxiety. Additionally, the study affirmed TEI's predictive role in trait anxiety and its mediating effect on the association with self-esteem. Moreover, it corroborated the documented negative relationship between TEI and trait anxiety (r= -0.554, p<0.001), the positive correlation between TEI and self-esteem, and the negative association between self-esteem and trait anxiety (r= -0.47, p<0.001). Despite acknowledged limitations, the findings offer valuable practical and theoretical insights into psychology. Furthermore, the study underscores the importance of TEI in promoting well-being by mitigating trait anxiety, while highlighting self-esteem as a potential risk factor associated with elevated trait anxiety levels. These findings underscore the intricate interplay of psychological attributes and anxiety levels, advocating for the cultivation of emotional intelligence as a preventive measure against anxiety disorders.
