Awareness of emotions, extensive emotional knowledge, and effective emotional management are characteristics of emotionally intelligent individuals. These competencies are expected to enable individuals using more adaptive decision-making styles (DMSs). Specifically, we predicted that trait emotional intelligence (EI) should be a positive predictor of intuitive and rational DMSs and a negative predictor of dependent, avoidant, and spontaneous DMSs, even after controlling for personality. Participants (N = 454) completed Slovene version of the Emotional Skills and Competence Questionnaire, the Decision-Making Styles Questionnaire, and the Zuckerman-Kuhlman Personality Questionnaire. Results supported the importance of trait EI on predicting DMSs: after controlling for personality, the trait EI accounted for 1 to 13% of the variance of the DMSs. Higher trait EI was associated with a more frequent use of intuitive, rational, and a less frequent use of dependent and avoidant DMSs. Results are in accordance with the assertion about the positive function of EI.
