Among people with suicide ideation most do not attempt suicide or die by suicide. In this online study of adult US Facebook users (n = 219), we examined capability for suicide, operationalized as fearlessness about death, and tolerance for psychological pain as potential variables that may explain why some people move from suicide ideation to suicidal behavior. Tolerance for psychological pain was significantly higher for participants who had never attempted suicide. Fearlessness about death was higher in participants who had attempted suicide, but not significantly. At high levels of psychological pain, one's belief in the ability to cope with psychological pain, a dimension of tolerance for psychological pain, was lower in participants with a history of suicide attempt than in participants who had never attempted suicide. The odds of suicidal desire were almost cut in half with each unit increase in participants' belief in their coping ability, whereas for each unit increase in fearlessness about death, the odds of suicidal desire increased by 65%. The Pearson correlation between tolerance for psychological pain and fearlessness about death was negligible. Our findings support a role for both tolerance for psychological pain and capability for suicide/fearlessness about death in the ideation-to-action framework of suicide.
在有自杀意念的人群中，大多数人不会尝试自杀或自杀身亡。在这项针对美国成年 Facebook 用户（n=219）的在线研究中，我们研究了自杀能力，即对死亡的无畏和对心理痛苦的容忍，这可能是解释为什么有些人从自杀意念转变为自杀行为的潜在因素。从未尝试过自杀的参与者对心理痛苦的容忍度明显更高。有过自杀尝试的参与者对死亡的无畏程度更高，但并不显著。在心理痛苦程度较高的情况下，一个人对自己能够应对心理痛苦的信念，即对心理痛苦容忍度的一个维度，在有自杀尝试史的参与者中低于从未尝试过自杀的参与者。参与者对自己应对能力的信念每增加一个单位，自杀欲望的几率就会降低近一半，而对死亡的无畏程度每增加一个单位，自杀欲望的几率就会增加 65%。对心理痛苦的容忍度和对死亡的无畏程度之间的皮尔逊相关系数可以忽略不计。我们的发现支持了在自杀意念到行动的框架中，对心理痛苦的容忍度和自杀能力/对死亡的无畏这两个因素的作用。
