Assessment of the lethality of suicide attempts is a neglected topic in the literature in this area. Based on the hypothesis that suicide attempters who choose a highly lethal method differ from those who use less lethal methods, we analyzed the characteristics of suicide attempters who used different suicide methods to determine demographic and clinical risk factors for the lethality of suicide methods. For this purpose, we used the Risk-Rescue Rating Scale to assess the lethality of the suicide method in a consecutive sample of 107 psychiatric inpatients with a recent suicide attempt (in 6 mo before hospitalization). The results demonstrated that patients who used a highly lethal method were younger and more frequently single. A novel finding of this study was that earlier age of onset of psychiatric symptoms and a higher number of previous hospitalizations were associated with the use of more lethal methods. In conclusion, patients who used more lethal methods differed from those who used less lethal methods. Identification of these differences may be necessary to implement specific suicide prevention strategies in patients with psychiatric conditions.
评估自杀企图的致命性是该领域文献中被忽视的一个话题。基于自杀企图者选择高度致命方法的人与使用不太致命方法的人不同的假设，我们分析了使用不同自杀方法的自杀企图者的特征，以确定自杀方法致命性的人口统计学和临床风险因素。为此，我们使用风险救援评分量表在最近（住院前 6 个月内）有自杀企图的 107 名住院精神科患者的连续样本中评估自杀方法的致命性。结果表明，使用高度致命方法的患者年龄较小且更常单身。这项研究的一个新发现是，精神病症状的发病年龄较早和之前住院次数较多与使用更致命的方法有关。总之，使用更致命方法的患者与使用不太致命方法的患者不同。识别这些差异可能对于在有精神疾病的患者中实施特定的自杀预防策略是必要的。
