Abstract

Emotional intelligence (EI) is reported to be inversely associated with emotional distress, although the potential role of negative repetitive thoughts in this relationship has not yet been explored. The current investigation examined the links between four facets of trait EI and emotional distress (i.e., symptoms of generalized anxiety disorder [GAD], depression, and social anxiety), and the mediating roles of worry, rumination, and post-event processing (PEP) in a sample of university students (N = 126). The EI facets of recognizing and regulating emotions in the self correlated negatively with emotional distress and negative repetitive thoughts. Regulation of emotions in others correlated only with levels of social anxiety. The role of negative repetitive thoughts was tested using three multiple mediator models. Worry independently mediated the link between EI and symptoms of GAD. Worry, rumination, and PEP independently mediated the link between EI and depression. Worry and rumination independently mediated the link between EI and social anxiety. Results suggest lower trait EI may lead to greater negative repetitive thoughts, which may increase the experience of emotional distress.
