执行功能缺陷（EF）被认为是自杀者经常观察到的“认知僵化”的可能解释。本文提供了一个系统的审查现有的文献测试EF和自杀之间的关系，在不同的诊断和人口统计学人群，使用有影响力的多维模型EF提出的组织框架。回顾了2014年1月之前发表的43篇关于该主题的期刊文章。总的来说，这些研究的结果提供了初步支持EF赤字和自杀之间的关联。然而，有一些证据表明，这种关联是缓和其他因素（例如，自杀未遂致死率）。重要的是，这种关系可能会因诊断组而异。具体来说，更多使用抑郁症样本的研究报告了一些阳性结果（75%），其次是混合诊断样本（54%）。相比之下，从双相情感障碍或精神病性障碍样本的研究中出现的阳性结果较少（分别为29%和33%），有些人甚至发现自杀倾向与精神病性障碍患者的EF更好相关。关于EF的特定维度和/或自杀倾向的各个方面之间的关系，这一次很难得出确切的结论。现有文献的局限性和相应的未来研究方向进行了讨论。
Deficits in executive function (EF) have been proposed as a possible explanation for the “cognitive rigidity” often observed in suicidal individuals. This article provides a systematic review of the existing literature testing relations between EF and suicidality, across various diagnostic and demographic populations, using the influential multidimensional model of EF proposed by as an organizing framework. Forty-three journal articles on this topic published before January of 2014 were reviewed. Collectively, results from these studies provide tentative support for an association between EF deficits and suicidality. However, there is some evidence that this association is moderated other factors (e.g., suicide attempt lethality). Importantly, this relationship may vary across diagnostic groups. Specifically, more studies that used depressive disorder samples reported some positive findings (75%), followed by mixed diagnostic samples (54%). In contrast, fewer positive findings have emerged from studies with bipolar or psychotic disorder samples (29% and 33% respectively), and some even found that suicidality is associated with better EF in individuals with psychotic disorders. Firm conclusions about relationships between specific dimensions of EF and/or aspects of suicidality are difficult to draw this time. Limitations of the existing literature and corresponding directions for future research are discussed.
