“…Despite its popular use as a tool to control incarcerated people’s behavior, there is not much evidence for the effectiveness of disciplinary segregation at reducing misbehavior. Rather, several studies have concluded that segregation is unrelated to institutional misconduct or related to higher levels of misconduct (Briggs et al, 2003; Huebner, 2003; Labrecque & Smith, 2019; Lucas & Jones, 2019; Meyers et al, 2023; Morris, 2016; Motz et al, 2021; Steiner & Cain, 2016; Toman, 2022; Wooldredge & Steiner, 2015; but see Steiner, 2009; Sundt et al, 2008). This study seeks to add to our understanding of the relationship between disciplinary segregation and misconduct by empirically testing whether and how misconduct varied after changes were made to Minnesota Department of Corrections’ (MnDOC) policies regarding the use of disciplinary segregation.…”
