Effectiveness of Dialectical Behavior Therapy (DBT) in a Forensic Psychiatric Hospital

Dialectical behavior therapy (DBT) has strong evidence in support of its effectiveness in reducing suicide attempts, anger, impulsivity, and substance abuse. It has been implemented in a variety of forensic settings to help with these challenges, despite limited research on the efficacy of DBT within this population. The current study presents treatment outcomes from an established DBT program in a maximum-security forensic facility. Outcomes included self-reported functioning, behavioral outcomes, and assessment of DBT skills knowledge among inpatients who participated in either comprehensive DBT or DBT skills training. Behaviorally, the study found a significant decrease in rates of patient assaults and reduced use of "Pro re nata" (PRN) medication for anxiety or agitation over the course of DBT treatment. During the first six months of treatment, self-reported symptoms of depression, emotional and behavioral dysregulation, and psychological inflexibility significantly decreased. Within this time frame, patients also displayed a significant decrease in the use of dysfunctional coping skills and a significant increase in knowledge pertaining to emotion regulation and interpersonal effectiveness. The results of this study largely support the use of DBT in forensic settings.
