This study addresses the reasons for school-based weapon carrying across th
ree diverse county-level contexts. Weapon carrying among students at school
has been, until very recently, neglected in research. Further, much of the
information that is available is non-comparative. Hence, whether the etiol
ogy of in-school weapon carrying is generalizable across diverse settings r
emains largely an unanswered question. The present study moves toward a tes
t of generalizability by comparing student weapon possession and its antece
dents in three geographically, economically, and culturally distinct commun
ities in Kentucky. Findings suggest that few differences exist across conte
xt regarding the etiology of school-based weapon carrying. Regardless of co
mmunity context, peer weapon carrying as well as criminal lifestyle are imp
ortant predictors of adolescents' carrying weapons to school.
