Opiate addiction and suicidal behaviors.

ABSTRACT

The authors tested the hypothesis that people addicted to opiates manifest more psychopathology in areas that have been identified as predictors for high risk of suicidal behavior than do normal control subjects. They gave 278 patients in a methadone maintenance program and 207 normal control subjects the index of Potential Suicide (IPS), a scale designed to assess suicidal risk. Using discriminate function analysis, the authors found that 87% of 100 of the methadone patients and 98% of 100 of the normal control subjects were correctly identified on the basis of the IPS data.
