Objective: This study examined the main effects and interaction effect of parenting attitudes and conversation hours between parent and child, by focusing on parental influence among factors impacting children’s happiness. Methods: This study used the data from 2,578 fourth grade elementary school students from the first waves of the Korean Child Youth Panel Study(KCYPS) 2018. The data were analyzed using correlation analysis and stepwise regression analysis. Results: First, there was a significant corelation between children’s happiness and socio-economic variables such as parental education level, family’s income, and family type. Second, it was found that the main effect of all sub-factors of parentingattitude and conversation hours between parent and child on children’s happiness was statistically significant. Third, only the interaction effect between structural parenting attitude and parent-child conversation hours was statistically significant. That is, children who had more conversations with parents with structural parenting attitudes providing guidelines ware reported to be particularly happy. Conclusion/Implications: This study is meaningful in examining overall quantitative and qualitative effects of the relationship between parent and child to understand parental factors impacting children’s happiness.
