Scholars and policymakers have advanced different arguments for why restrictive housing may improve or worsen inmate behavior, yet few studies exist that assess the impact of this housing on such outcomes. This study draws upon prior theory and research to hypothesize that inmate adjustment will worsen after placement in disciplinary segregation among a 3-year admission cohort of inmates from a large Midwestern state department of corrections (N = 40,979), and further that this effect will be more harmful to men. The results of our propensity score matching analyses reveal the use of disciplinary segregation is associated with a greater probability of misconduct among men and has no appreciable effect on women. These findings challenge the view that disciplinary segregation is an effective strategy for improving inmate behavior in prison. This work further highlights the need for continued research on the utility of restrictive housing.
