Inmate-on-inmate assault - A multilevel examination of prison violence

Most literature on inmate assaultive behavior considers only one level of analysis, thereby ignoring the importance of prison context on inmate behavior. This study improved on past research by combining inmate and prison-level data into a multilevel model explaining inmate-on-inmate, nondeadly assaults. Data from 1,054 male inmates in 30 prisons revealed that age and aggression were the most robust predictors of inmate-on-inmate assaults. In terms of multilevel effects, aggressive inmates were found to commit more assaults in prisons that were more crowded and had a greater percentage of younger inmates (e.g., younger than age 25). Policy implications and suggestions for a multilevel theory of prison violence are discussed.
