<p>This correlational study (<i>n</i> = 303) examined whether trait emotional intelligence mediates between trait mindfulness (broadly construed as a manifold of self-awareness, self-regulation, and self-transcendence) and mental health (state and trait anxiety, depression, and positive affect) and wellbeing (flourishing). Emotional intelligence was found to contain two components: Internally focused (understanding and utilizing one’s own emotions) and externally focused (understanding and utilizing other people’s emotions). Internally focused emotional intelligence. mediated between all aspects of mindfulness (except self-preoccupation) and all aspects of mental health and wellbeing; mindfulness alone explained 65% of the variance in internally focused emotional intelligence. Externally focused emotional intelligence did not show any mediational effects. Thus, the ability to understand and utilize one’s own emotions might be one possible mechanism through which the effects of trait mindfulness translate into wellness and wellbeing, although longitudinal and/or experimental research is necessary to fully support this conclusion.</p>
