Procedural justice serves a critical role in the interactions between criminal justice system actors and their clientele. Much of the literature in this area focuses on policing, and we know comparatively less about how procedural justice operates in corrections. Much like policing, it is likely that perceptions of correctional procedural justice vary within larger contexts. Using structured interviews with inmates (N=248) in Arizona at max, close, and medium custody, this study examines the association between conditions of confinement and perceptions of procedural justice, with a focus on how personality characteristics may modify this relationship. Results indicate that custody level does impact inmate perceptions of correctional officer procedural justice and that certain personality traits serve as protective or aggravating factors within the relationship between custody level and procedural justice. Policy implications and future research are discussed.
