The main objective of the research was to investigate the relationship between emotional intelligence and marrital quality. The aim was to examine if the results of self-reports and emotional inteligence tests explain the quality of marriage measured by self-reports and reports from the other partner. Second task was to examine if there are differences in quality of marriage between couples in different dyadic compostitiones of emotional intelligence. In this research there were 98 couples examined in ages from 19 to 60 years from Osijek area and near by. Instruments used in this research were: Questionnaire of emotional competence, Emotional analyse test, Emotion management test, Quality of marriage indeks and Big five Inventory. Contrary to the expectations, results are showing that the measurements of emotional intelligence do not contribute to explanation of self-reported marital quality. However, Emotional management test is statistically significant and positive predictor of marriage quality index of single spouse, but it doesn't contribute to explanation of global marriage quality evaluations (marriage happines). Furthermore the results show that the groups of couples with different dyadic compositions are different by marital quality by self-report of husband, but not from the self-report of the wife. In couples, the husbands in which both the husband and the wife estimate themselves highly on emotional intelligence have significantly higher estimations on marital quality, than the husbands of couples in which both the husband and the wife estimate themselves low on emotional intelligence.
