Effects of School Violence Victimization on Suicide Risk : Moderated Mediation of Loneliness and Family Support

Abstract

Background: School violence victimization is a serious issue that significantly affects adolescents' mental health, potentially increasing their risk of suicide. Prior research indicates that loneliness can mediate the relationship between school violence victimization and suicidal risk, while family support may act as a protective factor. However, the mechanisms underlying these relationships require further investigation.

Objective: This study examines the moderated mediation effect of loneliness and family support on the relationship between school violence victimization and suicidal risk among adolescents.

Participants and Setting: The study utilized survey data collected in October 2023 from 1,000 middle and high school students across various regions in South Korea.

Methods: Data were analyzed using SPSS and PROCESS Macro Model 14 to test direct, indirect, and conditional indirect effects. Bootstrapping techniques were applied to ensure statistical reliability.

Results: School violence victimization was positively associated with suicidal risk, with loneliness serving as a mediator. Additionally, family support moderated the indirect effect of school violence victimization on suicidal risk via loneliness, reducing the negative impact. Adolescents with higher family support exhibited a weaker indirect effect of loneliness on suicidal risk.

Conclusions: This study highlights the critical role of loneliness in linking school violence victimization to suicidal risk and underscores the protective function of family support. Intervention programs should prioritize reducing loneliness among victims of school violence and enhancing family support to mitigate suicidal risk.
