虽然一些理论家将情绪失调和自杀行为之间的关系概念化为直接关系，但最近的研究表明，这种关系可能是间接的，并通过重复体验某些行为（例如，非自杀性自伤（NSSI）在情绪失调严重的个体中很常见。然而，迄今为止，这项研究在两个范围都受到限制（例如，检查情绪失调的几个组成部分）和概括性（例如，过度强调本科生样本）。本研究试图通过检查NSSI在情绪失调的一个相关方面（即，在住院治疗的物质使用障碍（SUD）患者的高危样本中，存在低痛苦耐受性[DT]）和明确意图死亡的自杀行为。SUD患者（N = 93）完成了结构化访谈，评估过去的自杀行为和问卷调查，评估DT和NSSI。与假设一致，结果显示，低DT和终身自杀企图通过NSSI频率之间存在显着的间接关联。这些结果表明，通过NSSI经历暴露于痛苦和挑衅性事件可能是情绪失调的某些方面增加自杀行为风险的一种途径（与理论一致，即DT低的个体可能无法和/或不愿意从事自杀行为，除非他们经历了足够程度的痛苦和/或痛苦。或挑衅性事件能够改变他们的关系和经验的痛苦和死亡的恐惧）。(C)2013 Elsevier Inc.

Although some theorists conceptualize the relationship between emotion dysregulation and suicidal behavior as direct, recent research suggests that this relationship may be indirect and mediated by repeated experiences with certain behaviors (e.g., non-suicidal self-injury; NSSI) common among individuals with heightened emotion dysregulation. To date, however, this research has been limited in both scope (e.g., examining few components of emotion dysregulation) and generalizability (e.g., over-emphasis on undergraduate samples). This study sought to extend the research in this area by examining the mediating role of NSSI in the association between one relevant aspect of emotion dysregulation (i.e., low distress tolerance [DT]) and suicidal behavior with a clear intent to die among an at-risk sample of substance use disorder (SUD) patients in residential treatment. SUD patients (N = 93) completed a structured interview assessing past suicidal behavior and questionnaires assessing DT and NSSI. Consistent with hypotheses, results revealed a significant indirect association between low DT and lifetime suicide attempts through NSSI frequency. These results suggest that exposure to painful and provocative events through experience with NSSI may be one pathway through which certain facets of emotion dysregulation increase the risk for suicidal behaviors (consistent with theories that individuals low in DT may be unable and/or unwilling to engage in suicidal behavior unless they have experienced sufficient levels of painful and/or provocative events capable of changing their relationship with and experience of pain and fear of death).
