Inmate-On-Inmate Assault: A Multilevel Examination of Prison Violence

Abstract

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.

1. Missing data were substituted for with the appropriate measure of central tendency. All variables were centered on their grand means.
2.
2. Bivariate correlations were obtained for all levels of independent and dependent variables. None of the correlations were more than .50. Variance inflation factors were less than 4, indicating that multicollinearity was not an issue.
3.
3. To test for the stability of Level-2 coefficients, Level-2 variables were entered into this model alone as well as in pairs. The coefficients for the variables indicated as significant remained stable throughout this process.
