The prognostic value of the PCL-R in relation to the SUD treatment ending

Abstract

Scientific research about patients with substance use disorders (SUD) treated within the context of forensic compulsory addiction treatment is seldom available. Scientifically supported surveys regarding the treatability of SUD patients are rare. Some authors claim that the Psychopathy-Checklist-Revised (PCL-R) has value for predicting therapeutic success. PCL-R scores rely on extensive interview data and a detailed review of criminal records and social history. The scores reflect 1) the affective and interpersonal psychological traits; and 2) socially deviant conduct. This study was conducted by the forensic professional clinic at the hospital for Psychiatry and Neurology Hildburghausen. We assessed 102 male patients using the PCL-R. This investigation evaluated the Total score of the PCL-R and the score of Factor 1 and Factor 2 in relation to the end of treatment by court order. The results showed significant differences between patients who completed treatment and those who did not. Patients that dropped out of treatment had a higher score in PCL-R. With the use of the PCL-R it is possible to make a quantitative statement about which patients will complete treatment.
