The purpose of this study was to examine the relationship between mother’s emotional clarity and child’s problematic behavior by using the structure equation model. Mother’s depression was used as a mediating effect. Emotional clarity

demonstrates how much an individual is being clear about their own mood and emotion.

It surveyed 383 mothers with children aged between two and five who attended daycare and kindergarten in Gyeonggi province. As the measurement tools, it used the Trait Meta Mood Scale, the center for Epidemiological Studies-Depression and K-CBCL 1.5-5.

Hypothetical models were suggested for the possible paths and roles between mother’s emotional clarity, mother’s depression and child’s problematic behavior based on previous literature. The results are as follows: First, it showed a negative correlation between these variables: the mother’s emotional clarity, the mother’s depression and the children’s child’s problematic behavior. However, it showed a significant positive correlation between mother’s depression and child’s problematic behavior. Second, Mother’s depression acts as a complete mediation between mother’s emotion clarity and child’s problematic behavior. Based on these results, we discuss the significance as well as the restrictions of this study and make suggestions on directions for future research.
