영아의 내재화 및 외현화 문제 행동이 미디어 이용 시간에 미치는 영향: 동영상 시청을 중심으로 = Infants’ Internalizing and Externalizing Problem Behaviors and Their Effects on Media Use Time: Focusing on Video Viewing

다국어 초록 (Multilingual Abstract)

This study examined infants’ media use in response to increasingly early exposure to media devices and the accelerating trend toward the earlier onset of problem behaviors. The participants were 1,662 infants nationwide who were exposed to media such as animation and videos, along with their family members, drawn from the second wave of the Korean Childcare and Education Panel (Korea Institute of Child Care and Education, 2025). Data were analyzed using descriptive statistics, Pearson’s correlation coefficients, and hierarchical multiple regression analysis. The results were as follows. First, regarding the general tendencies of the major variables, the levels of internalizing and externalizing problem behaviors were slightly above the overall average. Among the subdomains, aggressive behavior showed a relatively higher mean score than the others. Second, regression analysis indicated that dual-income household status was a significant predictor of infants’ weekday media use. Specifically, infants in non-dual-income households were more likely to exhibit higher levels of weekday media exposure. For weekend media use, it was positively associated with infant age, lower levels of social withdrawal, and higher levels of aggressive behavior. It indicated that weekend media exposure increased as infant age increased, social withdrawal decreased, and aggressive behavior increased. Among these variables, aggressive behavior was identified as the strong predictor of weenkend media use. Based on these findings, this study suggests the need to enhance caregiving environments, emphasize parent-infant relationship building, and promote the productive use of digital media.
