Suicide rates among individuals with psychotic disorders are consistent across different locations and time periods. Psychotic individuals who died by suicide were younger and more prone to polysubstance abuse than previously observed.

Area of Science:

  • Psychiatry
  • Suicidology
  • Mental Health Research

Background:

  • Understanding the characteristics of individuals with psychotic disorders who die by suicide is crucial for prevention efforts.
  • Previous studies have provided limited comparative data on psychotic suicide cases across different geographic locations and time periods.

Purpose of the Study:

  • To compare the demographic and clinical characteristics of individuals with psychotic diagnoses who died by suicide in San Diego with a historical cohort from St. Louis.
  • To investigate the prevalence of depressive symptoms, substance abuse, and identified stressors in psychotic suicide cases.

Main Methods:

  • Retrospective analysis of 31 consecutive suicide cases with psychotic diagnoses from San Diego.
  • Comparison with 25 similar cases from St. Louis suicides conducted 25 years prior.

  • Data collection included demographic information, diagnoses, substance abuse history, depressive symptoms, suicidal communications, and stressors.

    • Main Results:

    • The proportion of psychotic subjects among all suicides was similar (less than 20%) in both San Diego and St. Louis samples.
    • San Diego psychotics were younger on average and exhibited higher rates of polysubstance abuse compared to the St. Louis group.
    • Depressive symptoms were prevalent in San Diego psychotics, regardless of a formal depressive syndrome diagnosis. Schizophrenics communicated suicidal intent similarly to other psychotic and non-psychotic individuals.

    Conclusions:

    • The demographic profile of psychotic suicide cases may shift over time, with younger individuals and polysubstance abuse becoming more prominent.
    • Depressive symptoms and suicidal communications are common in psychotic individuals who die by suicide, irrespective of specific diagnostic subgroups or formal depressive diagnoses.
    • Identified stressors were present in over half of all suicide subjects, highlighting their general importance in suicide etiology.
