This study examined the extent to which three approaches to violence prevention and response were associated with the incidence of school crime and disruption after accounting for the influence of demographic variables. Secondary data analyses were conducted with four subsets of the sample of principals who completed the National Center for Education Statistics' School Survey on Crime and Safety. Exploratory and confirmatory factor analyses conducted with Sample 1 (n = 426) and Sample 2 (n = 459), respectively, identified four approaches, labeled educational/therapeutic, control, security/enforcement, and crisis plans. Confirmatory factor analyses with Sample 3 (n = 382) validated the constructs of school crime and disruption. Hierarchical regression analyses with Sample 4 (n = 440) indicated that demographic characteristics (e.g., enrollment, neighborhood crime) were associated with school crime, school disruption, or both. After accounting for demographic influences, security/enforcement (e.g., law enforcement, suspensions) was significantly associated with school crime and disruption. (Contains 5 tables.)
