Child Maltreatment and the Mediating Effects of Bullying Victimization on School Engagement Among South Korean Youth in Orphanages and a National Sample

Background: Peer bullying is a global problem affecting youth around the world that can impact youth development including school engagement. The relationship between child maltreatment and school bullying victimization and perpetration is well known. However, few studies have explored the extent of bullying among vulnerable groups of adolescents. Youth in orphanage care may be at higher risk of both maltreatment and bullying because of the circumstances and stigma that brought them into care. This study aimed to examine peer bullying victimization among adolescents residing in orphanage care compared to a national sample of adolescents in South Korea, and to investigate the mediating effect of bullying victimization on the relationship between child maltreatment and school engagement. This comparison allowed for an examination of how caregiving contexts may differentially influence the impact of maltreatment and bullying on school engagement. Methods: Data from the national Korean Welfare Panel Study (KoWePS) 7th wave (n = 521) and a study of 153 South Korean adolescents in orphanage care were merged into one dataset (n = 675). Analysis included descriptive and bivariate statistics, two simple mediation analyses, and multiple regression analysis to verify mediation effects using PROCESS Macro. Results: Adolescents in orphanage care reported significantly higher bullying victimization and lower school engagement than the national sample. Negative correlations were identified between child maltreatment, bullying victimization, and school engagement among adolescents in orphanage care. Importantly, bullying victimization significantly mediated the relationship between child maltreatment and school engagement within this group. Conclusions: These findings highlight the complex relationship between maltreatment and bullying victimization, emphasizing the need for comprehensive interventions addressing both maltreatment and peer bullying to enhance school engagement among vulnerable youth.
