Evidence of Treatment Progress and Therapeutic Outcomes Among Adolescents With Psychopathic Features

Abstract

This study examined the relation between psychopathic features and treatment progress in a group of 86 delinquent boys. On admission to a specialized intensive treatment program, Psychopathic Checklist: Youth Version (PCL:YV) scores were computed and subsequently compared with treatment progress. Treatment progress was measured using a series of daily behavior rating scales and with a measure of institutional misconducts that required security intervention. The results found significant improvement in behavioral and security measures with treatment. PCL:YV scores did not interact with treatment progress. Regression analysis showed that initial, but not final, behavioral and security levels were predicted by PCL:YVscores. The final scores were predicted only by the duration of treatment. Furthermore, violent recidivism during a 4-year follow-up was predicted by final behavioral scores but not initial PCL:YV scores.
