Correlates of suicide and violence risk 1: The suicide risk measure

A measure of suicide risk was developed using items reported to discriminate suicidal patients from controls in various studies, and it showed that half of the items continued to discriminate between patient and control groups.

Abstract

A measure of suicide risk was developed using items reported to discriminate suicidal patients from controls in various studies. The new self-report scale was administered to 82 outpatients, 157 inpatients, and 83 college students. Using total scores, significant differences were found between the college sample and the two patient samples. The scale also discriminated between patients who reported one or more past suicide attempts and those who reported none. An independent cross-validation showed that half of the items continued to discriminate between patient and control groups. Sensitivity and specificity estimates were also determined. The test does not attempt to predict a specific rare event, i.e., suicide. It attempts to describe the degree to which a given individual reveals a set of characteristics that are similar to a suicide prototype.
