Abstract

This paper presents a comprehensive investigation of the criterion and incremental validity of trait emotional intelligence (trait EI or trait emotional self-efficacy), which is defined as a constellation of emotion-related self-perceptions and dispositions located at the lower levels of personality hierarchies (Petrides & Furnham, Citation2001). In Studies 1 and 2 (N=166 and 354, respectively) trait EI is shown to be related to measures of rumination, life satisfaction, depression, dysfunctional attitudes, and coping. Most relationships remained statistically significant even after controlling for Big Five variance. In Study 3 (N=212) trait EI is shown to be related to depression and nine distinct personality disorders. Most relationships remained significant, even after controlling for positive and negative affectivity (mood). It is concluded that trait EI has a role to play in personality, clinical, and social psychology, often with effects that are incremental over the basic dimensions of personality and mood.
