Summary
Personality disorders, particularly antisocial personality disorder, are linked to increased violence and criminal behavior. Treating comorbid conditions is crucial for managing antisocial traits over time.
Area of Science:
- Forensic Psychology
- Psychiatry
- Criminology
Background:
- Personality disorders are highly prevalent in prison populations.
- Antisocial personality disorder and traits are significantly associated with violent and criminal behavior.
Purpose of the Study:
- To highlight the link between personality disorders and criminal behavior.
- To recommend screening for violence risk during personality disorder assessments.
- To discuss treatment approaches for violent behavior in criminal populations.
Main Methods:
- Review of literature on personality disorders, violence, and criminal behavior.
- Analysis of treatment efficacy for cognitive behavior therapy and pharmacological interventions.
- Examination of factors influencing the natural course of antisocial personality traits.
Main Results:
- Cognitive behavior treatment shows limited efficacy for antisocial traits in criminal populations.
- Pharmacological treatment for repetitive aggressive behavior lacks strong evidence; benzodiazepines may increase violence risk.
- Comorbid conditions like substance use disorder, psychosis, and attention deficit disorders can delay the natural decrease of antisocial traits.
Conclusions:
- Violence risk screening is recommended during personality disorder diagnostics.
- Active treatment of comorbid conditions is essential for managing antisocial personality traits.
- Antisocial personality traits naturally diminish over time, but this process can be impeded by comorbidities.
