This chapter provides an outline of presentation slides, facilitator notations, and resources for Module 3 of the full-day training curriculum. Module 3 orients trainees to the underlying cognitive-behavioral framework and how evidence-based treatment programs use this general framework to help reduce instances of criminal thinking. Examples of criminal thinking specific to in-custody settings, go-to corrective responses (i.e., quick, back-pocket options), and how to manage adverse reactions to redirection efforts are reviewed. Most notably, this module introduces trainees to a three-step model for addressing criminal thinking that is referenced throughout the remaining training modules. Module 3 also highlights the importance of communicating criminal thinking events with other unit staff and clinicians for continuity of care purposes. Suggestions for documentation are offered with the understanding that procedures will ultimately be determined by institutional policy.
