BackgroundDetermining imminent risk of suicide continues to challenge psychiatrists. To this end, we test the clinical utility of a proposed set of diagnostic criteria for the suicide crisis syndrome (SCS) for prediction of imminent suicidal thoughts and behaviors prospectively.MethodOne hundred and seventy individuals hospitalized for suicidal thoughts and behaviors (STB) were evaluated within 72 hr of admission with measures assessing symptoms of the proposed SCS, history of STB, current ideation, and depression severity. Four‐eight weeks following discharge, STB were reassessed. Associations between SCS and postdischarge attempts were examined using chi‐square and logistic regression analyses. The receiver operator characteristic analysis was used to test the optimal number of symptoms required to meet proposed SCS criteria.ResultsThe syndrome was maximally informative about short‐term risk of postdischarge suicide behavior when all criteria were met. The syndrome conferred a sevenfold increase in risk of postdischarge suicide attempt, and significantly improved prediction by standard risk factors, which was null to limited.ConclusionsThe SCS diagnostic criteria are supported and appear to describe a clinically meaningful syndrome in a high‐risk population. Assessment of SCS may meaningfully improve clinical assessment of imminent suicide risk. Further study is needed to better understand the syndrome and its applicability in low‐risk populations.
