The authors examined the effects of neighborhood commitment and atmosphere on antisociality as mediated by collective efficacy (CE) using a multilevel analysis. Stratified sampling was used to collect data from 3,451 students and 545 teachers from 26 junior high schools in 4 qualitatively different communities. CE was indicated by students based on their perceptions of neighborhood "informal social control" (ISC) and "social cohesion and trust" (SCT) in their communities and their social information processing denoted antisociality. Teachers assessed the antecedent indices regarding the community environments within their school districts. Multilevel structural equation modeling was used to analyze the neighborhood-level effects of the antecedents on antisociality via CE. The results revealed that antecedents indirectly inhibited antisociality via ISC at the neighborhood-level. SCT directly inhibited antisociality at the individual-level. Implications for community interventions were discussed.
