This study examines ecological level correlates of adverse peer relationships among early adolescents (ages 12-14). Data analysis was conducted using the National Longitudinal Survey of Youth (NLSY). The sample was drawn from the mother–child data set, which included youth who in 2002 or 2004 were living with their mothers and enrolled in school. Eligible participants responded to at least 1 of the 13 items from the survey and their mothers responded to at least 1 of the 2 items measuring adverse peer relationships at Times 1 (2002/2004) and 2 (2004/2006). Multivariate hierarchical logistic regression was estimated. The presence of a learning disorder and adverse peer relationships at Time 1 (socio-demographics), perceptions of school environment (microsystem), and area of residence and perceptions of safety (exosystem) were all significantly associated with adverse peer relationships at Time 2. Assessing and targeting these ecological levels hold the potential to decrease adverse peer relationships among early adolescents.
