PCIT-ED Case Study of a Toddler with Internalizing Problem Behavior PCIT-ED Case Study

This case study examines the impact of parent-child interaction therapy (PCIT-ED), including emotional development components, on internalizing problems in toddlers. Three mothers and their toddlers, aged 3 to 5 years, participated after providing informed consent. PCIT-ED, an enhancement of Dr. Sheila Eyberg’s evidence-based PCIT, incorporates emotion naming and coaching to offer a more integrated approach. Pre- and post-intervention changes were assessed using the K-CBCL, DPICS, and ECBI, focusing on toddlers' internalizing behaviors, mother-child interactions, and maternal perceptions. Results indicated a decrease in internalizing behaviors, particularly anxiety and depression. Additionally, the quality of emotional expression and interaction between mothers and children improved, alongside significant positive changes in maternal perceptions. The global effectiveness of PCIT-ED for internalizing problems is established, but studies in Korea are lacking. This study suggests potential benefits for using PCIT-ED in Korean toddlers to foster emotional and social development.
