Cross-Validation of a Predictive Scale for Subsequent Suicidal Behavior in an Italian Sample

This article examines the predictive capability of 3 forms of a suicide prediction scale. In 91 parasuicide patients seen 1 year after discharge, 83% of repeat parasuicides (n=24) were correctly predicted. However, 67% of the “non repeatables” were incorrectly classified as likely to repeat, leading to a question about the predictive accuracy of the scale. Different forms of the suicide predictive scale were not significantly different from each other.
