People with mental disorders, particularly schizophrenia, face an increased risk of violence, especially when abusing alcohol or substances. Early antisocial behavior and psychopathic traits are stronger predictors than specific symptoms.

Area of Science:

  • Psychiatry
  • Criminology
  • Mental Health Research

Context:

  • Growing concern regarding violence in individuals with mental disorders.
  • Limited understanding of specific disorder aspects linked to aggression.
  • Need to clarify the strength of associations between mental disorders and violence.

Purpose:

  • To review international research on the relationship between mental disorders and violence.
  • To identify factors associated with increased violent behavior in psychiatric populations.
  • To compare the predictive value of symptoms versus other risk factors.

Summary:

  • Schizophrenia is associated with an elevated homicide risk.
  • While positive symptoms and disorganization were suspected predictors, their value is minimal compared to early antisocial behavior, psychopathic traits, and prior violence.

  • Alcohol and substance abuse significantly increase violent behavior risk, with a more pronounced effect in individuals with schizophrenia.

    • Impact:

    • Highlights that factors like early antisocial behavior and substance abuse are more critical in predicting violence than specific mental disorder symptoms.
    • Underscores the heightened risk of violence associated with comorbid substance abuse in schizophrenia patients.
    • Informs clinical practice and risk assessment strategies for individuals with mental disorders.
