The purpose of this research is to examine the effectiveness of an emotion coaching parenting program based on Gottman’s meta-emotion philosophy and the concept of emotion coaching, targeted at parents with young children. The program, which consists of ten sessions, aims to enhance parents’ meta-emotion philosophy, emotion coaching parenting behaviors, and parent-child relationships. Parents in the experimental group participated in the program once a week for approximately 90 minutes per session. Preand post-assessments were conducted, with the control group undergoing the same preand post-assessments under similar conditions. To verify the effectiveness of the program, more scientific emotional measurement methods were applied, including parent interviews and parent-child interaction experiments in addition to surveys. To validate the effectiveness of the program, paired t-test were conducted, and analysis of covariance (ANCOVA) was performed with pre-test scores as covariates to confirm the effects of program participation. The results showed that the emotion coaching parenting program improved parents’ parenting efficacy, reduced negative emotion regulation strategies regarding children’s emotions, and increased emotion coaching parenting behaviors. Notably, there was an increase in emotional awareness and acceptance of children’s negative emotions, as well as an increase in emotion coaching responses. Positive intervention behaviors in parent-child interactions increased, along with the duration of positive emotional responses directed towards children, and, importantly, there was a reduction in children's tense emotions. This research is significant in demonstrating the effectiveness of an emotion coaching parenting program that addresses the emotional aspects of the parent-child relationship in depth.
