The purpose of this retrospective decisional analysis study is to develop the prediction model of suicidal ideation. We used a Decision Tree Analysis using SPSS 23.0 program to explore predictors of suicide thoughts for 12,015 Korean adults aged 19-98 years. As a result, the most powerful predictor of suicidal ideation was the level of depression. Of people who suspected depression (CESD-11>16), 32.6% experienced suicidal ideation, which is 12 times higher than that of total subjects. The group with the highest rate of suicidal ideation was people who experienced financial difficulties in depression-suspected group and the rate of suicidal thoughts in this group was 56.7%, which was the highest rate. However, in the non-depressive group, the satisfaction of family relationship was the strongest predictor of suicidal ideation. In the non-depressive group, the rate of suicidal thoughts of people with high level of family relationship satisfaction and high level of health satisfaction was 0.6%, which was the lowest rate. The contribution of this study was that it provided the combination of variables to predict the risk groups of adult suicide. This study suggests that researchers and clinicians should consider comprehensively depressive symptoms, family relationships, economic difficulties, and health status to prevent the suicide of adults.
本回顾性决策分析研究的目的是开发自杀意念的预测模型。我们使用 SPSS 23.0 程序的决策树分析来探索 12015 名年龄在 19 至 98 岁的韩国成年人自杀想法的预测因素。结果表明，抑郁程度是自杀意念的最强预测因素。在疑似抑郁（CESD-11>16）的人中，有 32.6%的人出现自杀意念，是总人群的 12 倍。在疑似抑郁人群中，经济困难的人自杀意念发生率最高，为 56.7%，这是最高的发生率。然而，在非抑郁人群中，家庭关系满意度是自杀意念的最强预测因素。在非抑郁人群中，家庭关系满意度和健康满意度高的人出现自杀意念的比例为 0.6%，这是最低的比例。本研究的贡献在于提供了预测成年人自杀风险群体的变量组合。本研究表明，研究人员和临床医生应综合考虑抑郁症状、家庭关系、经济困难和健康状况，以预防成年人自杀。
