创伤后应激障碍（PTSD）与自杀意念和自杀企图有关；然而，研究主要集中在特定样本和有限范围的创伤上。我们在美国一个具有全国代表性的PTSD个体样本中研究了与27个创伤相关的自杀意念和自杀企图。数据来自全国酒精及相关疾病流行病学调查（N = 34,653）。评估参与者的终身创伤后应激障碍和创伤史、自杀意念和自杀企图。我们计算了每个创伤中报告自杀意念或自杀企图的个体的比例以及所经历的独特创伤的数量。大多数创伤与创伤后应激障碍患者的自杀意念和自杀企图有关与没有终身创伤或有终身创伤但没有创伤后应激障碍的个体相比。童年虐待、攻击性暴力和维和创伤的自杀意念（49.1%至51.9%）和自杀企图（22.8%至36.9%）的比例最高。战争和恐怖主义相关创伤的自杀意念和自杀企图率有很大差异。多重创伤增加了自杀倾向，每增加一次创伤，自杀意念率增加20.1%，自杀企图率增加38.9%。自杀意念和自杀企图的比率因创伤类型和创伤次数的不同而显著不同，这些因素可能对评估和管理PTSD患者的自杀行为很重要。
Posttraumatic stress disorder (PTSD) is associated with suicidal ideation and suicide attempt; however, research has largely focused on specific samples and a limited range of traumas. We examined suicidal ideation and suicide attempt relating to 27 traumas within a nationally representative U.S. sample of individuals with PTSD. Data were from the National Epidemiologic Survey of Alcohol and Related Conditions (N = 34,653). Participants were assessed for lifetime PTSD and trauma history, suicidal ideation, and suicide attempt. We calculated the proportion of individuals reporting suicidal ideation or suicide attempt for each trauma and for the number of unique traumas experienced. Most traumas were associated with greater suicidal ideation and suicide attempt in individuals with PTSD compared to individuals with no lifetime trauma or with lifetime trauma but no PTSD. Childhood maltreatment, assaultive violence, and peacekeeping traumas had the highest rates of suicidal ideation (49.1% to 51.9%) and suicide attempt (22.8% to 36.9%). There was substantial variation in rates of suicidal ideation and suicide attempt for war and terrorism-related traumas. Multiple traumas increased suicidality, such that each additional trauma was associated with an increase of 20.1% in rate of suicidal ideation and 38.9% in rate of suicide attempts. Rates of suicidal ideation and suicide attempts varied markedly by trauma type and number of traumas, and these factors may be important in assessing and managing suicidality in individuals with PTSD.
