This study explored the link between individual characteristics, immediate social environment variables, and the likelihood of preschoolers being nominated as aggressors or victims. The novelty of the study lies in its comprehensive longitudinal examination, using a multi-informant approach, of how family dynamics, peer relations, teacher-child interactions, and community factors are related to preschool aggression within the context of Bronfenbrenner’s ecological system theory.Methods: Data was collected at two points, four months apart, to investigate the interplay among sociodemographic, individual, family, and school factors and subsequent child aggression. The study included 394 children (184 girls, 210 boys), aged 3 to 6 years (M = 4.36, SD = 0.87). Caregivers completed questionnaires on socioeconomic status, community relationships, children’s emotional regulation, and family functioning. Teachers rated closeness with each child, while children nominated liked and disliked peers, as well as those exhibiting aggressive or victimized behaviour.Results: Logistic regression models revealed stronger associations between peer aggression and victimization and individual factors over microsystems. Surprisingly, community cohesion showed a robust positive link with an increased likelihood of children being nominated as victims, challenging the assumption that positive parenting practices and strong community cohesion always leads to positive outcomes for individuals.Discussion: The study advances theoretical understanding by examining how factors within preschoolers’ microsystems influence aggressive behaviors, contributing to more holistic models for addressing preschool aggression and victimization in schools. The findings highlight the significance of targeted interventions, emphasizing early identification of aggression or victimization signs and customized programs for social and emotional skill development. Addressing parental stress and interparental conflict is crucial. Additionally, community-based initiatives, like strengthening support networks, play a pivotal role in fostering healthier social dynamics among preschoolers.Keywords: peer aggression, peer victimization, preschool, microsystem, community cohesion
