This study examined factors that distinguish adolescent weapon carrying in school compared to only in the community. We look at how experiences (offending, victimization, and gang-involvement) and perceptions (school, neighborhood, individual) toward violence are associated with self-reported weapon carrying in these two locations. Data came from two waves of the University of Missouri – St. Louis Comprehensive School Safety Initiative, a longitudinal study on the causes and consequences of school violence. Multinomial logistic regression was used to predict weapon carrying among three mutually exclusive categories: those who do not carry, those who carry only in the community, and those who carry both in school and in the community. We find that victim/offenders are more likely to carry weapons regardless of context, but school weapon carrying is positively associated with fatalism and gang-involvement. One school factor, school commitment, impacted carrying both inside and outside of school. Our results identify unique factors that can reduce adolescent weapon carrying in general and specifically in school.

这项研究探讨了区分青少年在学校携带武器与仅在社区携带武器的因素。我们研究了这两个地点的经历（犯罪、受害和参与帮派）和对暴力的看法（学校、社区、个人）如何与自我报告的携带武器相关。数据来自密苏里大学圣路易斯分校综合学校安全倡议的两波研究，这是一项关于校园暴力原因和后果的纵向研究。使用多项逻辑回归来预测三个相互排斥的类别中的武器携带情况：不携带武器的人、仅在社区携带武器的人以及在学校和社区携带武器的人。我们发现，无论背景如何，受害者/犯罪者都更有可能携带武器，但学校携带武器与宿命论和帮派参与呈正相关。学校因素之一，即学校承诺，影响着校内和校外的表现。我们的研究结果确定了可以减少青少年武器携带的独特因素，特别是在学校。
