摘要:Objective: This study analyzed mother-child interactions in a stressful situation each second by mother’s emotional regulation level. Methods: The study was conducted with 16 mothers and their 5-year-old children playing a teaching task for 15 min. During the interactions, the participants were videotaped and examined. Furthermore, qualitative analysis was used for analyzing mother-child interactions in detail by creating a situation that maximizes the stress and frustration of the mother and child. Results: The results showed that maternal humor and affection were significantly related to child positive emotion and that maternal coaching closely correlated with the child pride, pleasure, and whining. Additionally, maternal intrusive behavior showed a positive correlation with child anger. Lastly, mothers with higher levels of emotional regulation more often expressed affection to their children. They were more actively involved in the tasks and used fewer positive or negative directive expressions. Therefore, children of this group expressed more positive emotions. Conclusion: These findings suggests that programs improving parental emotional reaction and emotion regulation should be developed.
