A suicide attempt is an established risk factor for subsequent suicide attempts and suicide. Nonetheless, the prediction of future suicidal behavior is poor. The lethality of previous suicidal behavior may be informative to better understand future suicide risk among patients hospitalized for suicidal thoughts and behavior. The current study examined whether the lethality of patients' index (most recent suicidal episode at hospitalization), first, and worst suicidal episode predicts the lethality of one's most lethal suicide attempt during a 2-year follow-up period.
A total of 98 patients hospitalized at an emergency department for high suicide risk (i.e., acute suicidal ideation or a suicide attempt) were included in the study.
Results indicated that the lethality of the index suicidal episode predicted the lethality of the worst suicide attempt during a 2-year follow-up period.
These findings extend a growing literature examining risk factors that influence the progression toward high lethality suicidal behavior.
自杀企图是随后自杀企图和自杀的既定风险因素。尽管如此，对未来自杀行为的预测仍然很差。先前自杀行为的致命性可能有助于更好地理解因自杀意念和行为住院的患者的未来自杀风险。本研究探讨了患者指数（住院时最近一次自杀发作）、首次和最严重自杀发作的致命性是否可以预测在 2 年随访期间最致命自杀企图的致命性。
共有 98 名因高自杀风险（即急性自杀意念或自杀企图）而在急诊科住院的患者纳入研究。
结果表明，指数自杀发作的致命性预测了在 2 年随访期间最严重自杀企图的致命性。
这些发现扩展了越来越多的研究自杀行为风险因素的文献，这些因素影响了向高致命性自杀行为的进展。
