Offenders with mental health problems and problematic substance use: Affective psychopathic personality traits as potential barriers to participation in substance abuse interventions

Substance abuse is related to re-offending, and treatment of substance abuse may reduce criminal recidivism. Offender characteristics including problem severity, violence risk and psychopathic personality traits may be positively or negatively associated with participation in substance abuse treatment. We explored the relationships between such characteristics and participation in substance abuse interventions among Swedish offenders with mental health problems and problematic substance use. Our analyses revealed that problem severity regarding drugs, employment, and family/social situations predicted intervention participation, and that affective psychopathic personality traits were negatively associated with such participation. Thus, affective psychopathic personality traits could be considered as potential barriers to participation in substance abuse interventions. Among offenders with mental health problems and problematic substance use, such personality traits should be taken into account in order to optimize treatment participation and treatment outcome. Approaches used in cognitive-behavioral therapy (CBT) and dialectical behavioral therapy (DBT) could be applicable for these patients.
