The majority of suicide decedents die on their initial attempt. To bring attention to suicide decedents without a suicide attempt history, the current study explored their demographic, clinical, and suicide-related characteristics. The data were derived from the Korea National Investigation of Suicide Victims Study, which assessed all suicide cases from 2013 to 2017 recorded in police investigation reports. We compared suicide decedents with and without a history of nonfatal attempts using the Korea Psychological Autopsy Checklist for Police Records (K-PAC). Out of 5228 cases included in our study, 3147 (60.2%) died on their first suicide attempt. Demographically, those who were male, older than 65, employed, and married/widowed were more likely to die on their initial attempt. Clinically, those who died on their initial attempt were more likely to have never been diagnosed with psychiatric disorders, whereas those who died on a repeated attempt were more likely to have been diagnosed with mood disorders. In terms of suicide-related factors, experiencing relationship problems and complaining about physical discomfort were associated with dying on an initial attempt. Depressed affect, self-harming behaviors, and talking about suicide or death were associated with repeated attempts.

在韩国全国样本中比较有和没有自杀未遂史的自杀死者的心理尸检研究

大多数自杀死者在初次尝试时死亡。为了引起对没有自杀未遂史的自杀死者的关注，本研究探讨了他们的人口统计学、临床和与自杀相关的特征。这些数据来自韩国全国自杀受害者调查研究，该研究评估了警方调查报告中记录的 2013 年至 2017 年所有自杀案件。我们使用韩国警方记录心理尸检清单 (K-PAC) 比较了有和没有非致命企图史的自杀死者。在我们研究的 5228 例病例中，3147 例（60.2%）死于第一次自杀未遂。从人口统计学上看，那些男性、65 岁以上、就业和已婚/丧偶的人更有可能在初次尝试时死亡。临床上，那些在第一次尝试中死亡的人更有可能从未被诊断出患有精神疾病，而那些在反复尝试中死亡的人更有可能被诊断出患有情绪障碍。在与自杀相关的因素方面，经历关系问题和抱怨身体不适与初次尝试死亡有关。抑郁情绪、自残行为以及谈论自杀或死亡与反复尝试有关。
