Emotional intelligence, which consists of adaptive emotional functioning, may be a foundation for optimism. This meta-analysis examined the relationship between emotional intelligence and optimism across 6889 participants from 25 independent samples. Across studies, a higher level of emotional intelligence was associated with greater optimism with a weighted effect size of, r = .35, p < .001. Measurement approach and country of participants moderated the effect size. These results have relevance for the design of positive psychology interventions.
