As South Korea has the highest incidence of completed suicides, the present study aimed to investigate the predictive power of the variables that have been associated with suicide attempts in Korean patients diagnosed with depression.
Hundred participants were divided into two groups: suicide attempters (31%) and suicide non-attempters (69%). Participants with a history of more than one suicidal attempt were assigned to the suicide attempter group. A hierarchical logistic regression analysis was performed to determine the predictive strengths of the variables that were likely to be associated with suicide attempts.
After controlling for the effects of such variables as the severity of depressive symptoms, life stress events and impulsivity, the severity of past suicidal ideation was the most important predictive factor for discriminating suicide attempters from suicide non-attempters. The odds ratio for attempting suicide relative to not attempting suicide increased by a factor of 4.408 for each unit of increase in suicidal ideation.
The present study suggests that the most severe suicidal ideation throughout one's entire life should not be overlooked and may be a major predictor of the risk of suicide.
由于韩国的自杀既遂发生率最高，本研究旨在调查与被诊断为抑郁症的韩国患者自杀未遂相关的变量的预测能力。
100名参与者被分为两组：自杀未遂者（31%）和非自杀未遂者（69%）。有多次自杀未遂史的参与者被分配到自杀未遂者组。进行了分层逻辑回归分析，以确定可能与自杀未遂相关的变量的预测强度。
在控制了抑郁症状严重程度、生活应激事件和冲动性等变量的影响后，过去自杀意念的严重程度是区分自杀未遂者和非自杀未遂者的最重要预测因素。自杀意念每增加一个单位，自杀未遂相对于未自杀未遂的优势比增加4.408倍。
本研究表明，一生中最严重的自杀意念不应被忽视，可能是自杀风险的主要预测因素。
