Abstract

This study examined whether widely accepted suicide risk factors are useful in predicting suicide-related hospitalization, beyond history of a suicide attempt, in high-risk treatment-seeking veterans with depression and substance dependence. Negative mood regulation expectancies were the only significant predictor of hospitalization during 6-months of outpatient treatment. History of a suicide attempt was the only significant predictor of hospitalization during the one-year follow-up period. Results suggest that within high-risk populations, standard suicide risk factors may not identify individuals who will engage in suicidal behaviors resulting in hospitalization. Assessing negative mood regulation expectations may assist in identifying those most at risk.
