Abstract
Objectives This study tracked the behavior of male inmates housed in the general inmate
populations of 70 different prison units from a large southern state. Each of the inmates
studied engaged in violent misconduct at least once during the first 2 years of incarceration
(n = 3,808). The goal of the study was to isolate the effect of exposure to short-term
solitary confinement (SC) as a punishment for their initial act of violent behavior on the
occurrence and timing of subsequent misconduct.
Methods This study relied upon archival longitudinal data and employed a multilevel
counterfactual research design (propensity score matching) that involved tests for group
differences, event history analyses, and trajectory analyses.
Results The results suggest that exposure to short-term solitary confinement as a pun-
ishment for an initial violence does not appear to play a role in increasing or decreasing the
probability, timing, or development future misconduct for this particular group on inmates.
Conclusions Upon validation, these findings call for continued research and perhaps a
dialog regarding the utility of solitary confinement policies under certain contexts. This
unique study sets the stage for further research to more fully understand how solitary
impacts post-exposure behavior.
