In this study, to measure the emotion awareness of the children and adolescents, the Emotion Awareness Questionnaire for children (EAQ), which was developed by Rieffe, Meerum Terwogt et al.(2007) and revised by Rieffe, Oosterveld, Miers, Meerum Terwogt & Ly(2008) was validated. The questionnaire was conducted in September 2015 on 1454 students of elementary schools, middle schools and high schools. Then, the exploratory factor analysis, the reliability analysis & the confirmatory factor analysis were conducted, Also, for the convergent validity and the discriminant validity, the correlation analyses with the Trait Meta-Mood Scale(TMMS), Emotion Expression Scale for Children(EESC), Difficulties in Emotion Regulation Scale (DERS), Marlowe-Crowne Social Desirability Scale, and Child-Adolescent Self-reported Executive Function Difficulty Screening Questionnaire were conducted. The analysis resulted in the six-factor structure which was the same as the original scale except the two items which had low factor loading: Differentiating Emotions, Verbal Sharing of Emotions, Not Hiding Emotions, Bodily Awareness, Attending to Others’ Emotions, Analyses of Emotions. However, some items of ‘Attending to others Emotions’ are loaded in other two subscales so it seems that ‘awaring own emotion’ and ‘awaring others’ emotion’ are the same dimension for Korean children and adolescents. Finally, the significance and limitations of this research were discussed.
