Physical Violence Inside Prisons

This study estimates prevalence rates of inmate-on-inmate and staff-on-inmate physical victimization. Inmate participants were drawn from 13 adult male prisons and 1 female prison operated by a single mid-Atlantic state. A total of 7,221 men and 564 women participated. Rates of physical victimization varied significantly by gender, perpetrator, question wording, and facility. Prevalence rates of inmate-on-inmate physical violence in the previous 6 months were equal for males and females. Men had significantly higher rates of physical violence perpetrated by staff than by other inmates. By facility, inmate-on-inmate prevalence rates ranged from 129 to 346 per 1,000, whereas the range for staff-on-inmate was 83 to 321 per 1,000 (but the difference was not statistically significant).
