Past research has shown that adults can report their own skill level on four dimensions of emotional intelligence, using the Trait Meta-Mood Scale (TMMS). This study assessed children's ability to self-report on the emotional attention, emotional clarity, and emotional repair dimensions of emotional intelligence, using a modification of the above scale, the Trait Meta-Mood Scale for Children (TMMS-C). A total of 691 elementary school children from grades 3 to 7 completed a 28-item scale combining adapted items from the TMMS and a measure of dispositional optimism. Subjects also completed scales measuring depressive symptoms, social anxiety and social avoidance, and life satisfaction, as well as a friendship assessment. Internal validity of the TMMS-C was tested by assessing the reliability of subscales. Convergent external validity was assessed by examining the relation between children's self-reports on the TMMS-C and their self-reports on other measures of emotion regulation. Divergent external validity was assessed by examining the relation between self-perceived emotional competence (TMMS-C) and measures of perceived and objective social competence. In addition, the relation between TMMS-C subscales and children's adjustment was assessed, using a measure of life satisfaction. Results indicated that the measure had adequate internal reliability (subscale Cronbach's alphas .58 to .76) and that children's reports about their emotional competence were linked in important ways to their social competence and adjustment.
