Early recognition of a high-risk group impending suicide is important. We aimed to compare warning signs depending on the nature of the psychiatric disorder and whether it was a documented diagnosis.
Data of suicide decedents were collected from police records from 2013 to 2017. We evaluate psychiatric symptoms and warning signs in three aspects (language, behavior, and affect) using the Korea-Psychological Autopsy Checklist for Police Records (K-PAC-PR).
A total of 13,265 suicide decedents were recruited for this study. Of them, 66.9% of females and 46.7% of males diagnosed psychiatric disorders, with depressive disorder being the most common one. Warning signs were observed in 93.0% of suicide decedents. They were observed more in those who were diagnosed with psychiatric disorders, especially in those with a depressive disorder. "Talking about dying or suicide" was the most common warning sign in all groups, and "apathetic behavior" was the most related warning sign for depressive disorder. Especially for "talking about dying or suicide," the proportion of observed "within a week" was high, making it valuable as a warning sign.
Warning signs were commonly found in suicide decedents regardless of gender. They were more common among the decedents diagnosed with psychiatric disorders, especially among those with a depressive disorder.
及早识别有自杀倾向的高危人群很重要。我们旨在比较不同精神障碍性质和是否有记录诊断的警示信号。
从 2013 年至 2017 年警方记录中收集自杀死者的数据。我们使用韩国警方记录心理尸检清单（K-PAC-PR）从语言、行为和情感三个方面评估精神症状和警示信号。
本研究共纳入 13265 名自杀死者。其中，女性中 66.9%和男性中 46.7%被诊断为精神障碍，最常见的是抑郁症。93.0%的自杀死者存在警示信号。在被诊断为精神障碍的死者中更为常见，尤其是在患有抑郁症的死者中。“谈论死亡或自杀”是所有组中最常见的警示信号，而“冷漠行为”是与抑郁症最相关的警示信号。特别是“谈论死亡或自杀”，观察到“在一周内”的比例较高，使其成为有价值的警示信号。
无论性别如何，自杀死者中普遍存在警示信号。在被诊断为精神障碍的死者中更为常见，尤其是在患有抑郁症的死者中。
