This study sought to examine psychiatric and childhood traumatic event correlates of multiple suicide attempts (MSA) compared with single suicide attempts (SSA) in 2 nationally representative samples of the United States general population. Data came from the National Comorbidity Survey (n = 5,401; age 18-54; response rate = 82.4%) and the National Comorbidity Survey Replication (n = 4,083; age 18-54; response rate = 70.9%). Multiple logistic regressions were used to compare individuals with MSA to those with a SSA on the variables of interest after adjusting for sociodemographic variables. Individuals with a history of MSA had significantly higher odds of experiencing several traumatic events in childhood in the 2 surveys. Most notably, comorbidity of 3 or more mental disorders and the presence of at least 1 anxiety disorder distinguished individuals with MSA from those with a SSA in both surveys, suggesting the potential importance of these variables in association with multiple suicide attempts.
本研究旨在在美国一般人群的两个具有全国代表性的样本中，考察多次自杀未遂（MSA）与单次自杀未遂（SSA）相比的精神疾病及童年创伤事件相关性。数据来自全国共病调查（n = 5401；年龄18 - 54岁；应答率 = 82.4%）和全国共病调查复制版（n = 4083；年龄18 - 54岁；应答率 = 70.9%）。在调整社会人口统计学变量后，采用多元逻辑回归对多次自杀未遂者与单次自杀未遂者在感兴趣的变量上进行比较。在这两项调查中，有多次自杀未遂史的个体童年经历多种创伤事件的几率显著更高。最值得注意的是，在两项调查中，三种或更多精神障碍的共病以及至少一种焦虑障碍的存在将多次自杀未遂者与单次自杀未遂者区分开来，这表明这些变量在与多次自杀未遂的关联中可能具有重要意义。
