Relationship between emotional intelligence and aggression: A systematic review

Emotional intelligence (EI), defined as a set of abilities for perceiving, using, understanding, and managing emotions, has been associated with a better psychosocial adjustment. Empirical studies have found a positive relationship of EI with social function and a negative one with conflicts in social relationships. The purpose of this study was to systematically review available evidence on the relationship between EI and aggression. PubMed, PsycINFO and Scopus were searched for relevant articles in English and Spanish, and 19 eligible studies were identified. Together, these studies provide strong evidence that emotional abilities and aggressive behavior are negatively related: people with higher EI show less aggression. This relationship appears to be consistent across ages (from childhood to adulthood), cultures, types of aggression, and EI measures. Few studies have assessed EI using ability tests, and none of the eligible studies was longitudinal or experimental. These findings are discussed in relation to future research on aggression and strategies to prevent and manage it based on EI. (c) 2014 Elsevier Ltd. All rights reserved.
