Suicide attempters represent a heterogeneous group, whereby repeat-suicide attempters possess a differing risk profile compared with single-suicide attempters. Using cross-sectional data from a nationally representative sample of 18,185 people in custody in the United States, the current study compared repeat-suicide attempters (n = 1,549) to single-suicide attempters (n = 1,146), and compared single- and repeat-suicide attempters to suicide ideators (n = 1,741), on a range of correlates. Multiple suicide attempts were more commonly reported than a single attempt, especially among women. Several factors differentiated repeat-suicide attempters from single-suicide attempters, with men and women exhibiting some similarities and differences in correlates of repeat- versus single-suicide attempts. Several factors also differentiated single- and repeat-suicide attempters from suicide ideators. Overall, repeat-suicide attempters exhibited greater vulnerability to respond to stress through means of suicide as compared with single-suicide attempters. Discussion emphasizes the importance of acknowledging the heterogeneity of suicide attempters.

自杀未遂者代表异质性群体，重复自杀未遂者与单自杀未遂者相比具有不同的风险特征。使用来自美国18,185名在押人员的全国代表性样本的横截面数据，当前研究比较了多次自杀未遂者（n = 1,549）和单自杀未遂者（n = 1,146），并对单次自杀和重复自杀进行了比较。 -suicide未遂自杀建议者（ñ= 1,741），并包含一系列相关系数。据报道，多次自杀尝试比一次自杀尝试更为普遍，尤其是在女性中。有几个因素使重复自杀未遂者与单一自杀未遂者有所区别，男性和女性在重复自杀与单一自杀未遂的相关性方面表现出一些相似之处和不同之处。几个因素也使单自杀和复自杀的尝试者与自杀意识形态者有所区别。总体而言，与单自杀企图者相比，重自杀企图者表现出更大的脆弱性以自杀方式应对压力。讨论强调承认自杀未遂者的异质性的重要性。
