Abstract

Child abuse is a serious social issue, particularly in the context of urban migration, informal labor, and the weakening of community support networks. This article examines the case of B.T.H., a four-year-old girl in Hanoi in 2026, as a case study to analyze child abuse from the perspective of community psychology. The study uses secondary document analysis based on official media reports, publicly available investigation information, and relevant academic literature. Its analytical framework draws on the socioecological model, intergenerational trauma theory, and community psychology. The findings show that the case reflects the interaction of family trauma, social isolation, declining community responsibility, and gaps in early detection mechanisms. The article proposes a shift from post-incident intervention to proactive prevention through interdisciplinary support and community-based child protection.

Keywords: Case study, child abuse, child protection, community psychology, early intervention, intergenerational trauma.
