Suicide by psychotics

Abstract

The authors studied 31 cases with psychotic diagnoses from a consecutive series of 204 suicides in San Diego. They were compared to 25 similar cases from 134 suicides gathered in the city of St. Louis and St. Louis county 25 years earlier. The proportion of psychotic subjects (less than 20%) in the two samples was similar. The San Diego psychotics were younger on the average than those from St. Louis and had more polysubstance abuse than alcoholism. Only rarely did psychotics in either sample commit suicide by particularly "crazy" methods. In the San Diego suicides, the psychotics without a depressive syndrome had as many depressive symptoms as those with a depressive syndrome. Schizophrenics in the San Diego sample made suicidal communications just as often as the other psychotics and the nonpsychotics. Fewer schizophrenics than other psychotics or nonpsychotics had stressors identified at the time of death, but over half of all the subjects did have them.
