This error did not impact the results or conclusions. All versions of this article have been corrected.] Dialectical Behavior Therapy for Justice-Involved Veterans (DBT-J; Edwards, Dichiara, Epshteyn, et al., 2022) was recently developed as an integrative psychotherapy + case management intervention to address the range of complex criminogenic, mental health, substance use, and case management needs commonly faced by justice-involved veterans. Research to date suggests delivery of DBT-J to be both acceptable and feasible (Edwards, Dichiara, Epshteyn, et al., 2022). However, data on therapeutic change experienced by DBT-J participants has been limited. The present study represents an initial investigation into longitudinal changes in criminogenic risk, psychological distress, substance use, case management needs, and quality of life experienced by 20 justice-involved veterans across their course of DBT-J participation. Results reflected notable improvements across treatment targets from pre- to posttreatment; these gains were largely maintained at 1-month follow-up. Such findings attest to the potential utility of DBT-J and to the need for continued research into the efficacy of this intervention. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
