Objective: The purpose of this study is to identify the longitudinal reciprocal relationship between young children’s vocabulary ability and physical aggression in young children.
Methods: Two waves of panel data(2013/2015) from the Panel Study of Korean Children were analyzed in this study by using an adapted version of Autoregressive cross-lagged modeling. A total of 306 five-year-old and seven- year-old preschoolers, and their mothers participated in the study. Autoregressive cross-lagged modeling for multiple groups was conducted by using AMOS 24.0.
Results: First, vocabulary ability and physical aggression showed stability over time. Second, young children’s vocabulary ability(t) had a statistically significant effect on physical aggression(t+1).
Conclusion/Implications: This study confirmed the interrelationships of young children’s vocabulary ability and physical aggression by examining longitudinal data using the longitudinal analysis method. This study highlights the importance of developing interventions to support language development with aggressive children. The results of the present study can be used as a source in developing policies for aggressive children and their parents.
