This study examined the effects of the awareness of risky peer group behaviors (e.g., drug use, students carrying weapons, or vandalism on school grounds) on students' experiences of school victimization. This is one of the few studies conducted in the Middle East that examine issues of school violence. This article (Part I) focuses on elementary school students. Part II is forthcoming in a future article and will focus on junior high school students. The sample was drawn from central and northern Israel and consisted of 1346 Arab and 1478 Jewish students (4th-6th grades). Students completed an anonymous self-report questionnaire, which was based on the California School Climate Survey (Furlong et al, 1997). The findings from a hierarchical regression analysis show that elementary school students' awareness of risky peer group behaviors in school contexts is one of the strongest predictors of their own personal victimization, controlling for gender, ethnicity, and grade level. Theoretical and practical implications are discussed.
