Emotional intelligence and relationship quality among couples

To assess whether emotional intelligence (EI) is related to self-assessed relationship quality, an ability test of EI and measures of relationship quality were administered to 86 heterosexual couples in a university setting.  Couples with both partners low on EI tended to have the lowest scores on depth, support, and positive relationship quality and the highest scores on conflict and negative relationship quality; couples with both partners high on EI did not consistently have higher scores on positive outcomes and lower scores on negative outcomes than couples with one high-EI partner.
