感知一个人的内部生理感觉是一个被称为内感受的过程。一些研究表明，不良的内感受可能会促进危险的自我伤害。在2项研究中，我们调查了具有不同程度自杀倾向的个体的内感受能力。在研究1中，我们比较了对照组（n = 27）和自杀意念者（n = 35），计划者（n = 14）和自杀者（n = 30）的内感受。我们发现那些有自杀倾向的人比对照组有更差的内感受。此外，规划者比规划者或构思者报告更差的内感受。在研究2中，我们比较了有（n = 136）或没有（n = 459）企图自杀的精神科门诊患者的内感受。我们再次发现，与非吸烟者相比，吸烟者的内感受更差。此外，我们发现，最近的尝试更强烈地与内感受性缺陷比遥远的尝试。总之，我们的研究结果表明，内感受在自杀倾向的个体中受损。此外，内感受受到干扰的程度不仅可以区分那些想要自杀的人和那些试图自杀的人，而且可以区分最近和遥远的自杀未遂者。受损的内感受可能对严重的自我伤害很重要;因此，重新建立与身体的联系可能有助于预防自杀行为。
Sensing one's internal physiological sensations is a process known as interoception. Several lines of research suggest that poor interoception may facilitate engagement in dangerous self-harm. In 2 studies, we investigated interoceptive abilities in individuals with differing degrees of suicidality. In Study 1, we compared interoception in controls (n = 27) and suicide ideators (n = 35), planners (n = 14), and attempters (n = 30). We found that those with suicidality had worse interoception than controls. Further, attempters reported worse interoception than planners or ideators. In Study 2, we compared interoception in psychiatric outpatients who had (n = 136) or had not (n = 459) attempted suicide. Again, we found that attempters reported worse interoception than nonattempters. In addition, we found that recent attempts were more strongly associated with interoceptive deficits than distant attempts. Together, our findings suggest that interoception is impaired in individuals with suicidality. Furthermore, the extent to which interoception is disturbed may differentiate not only between those who desire suicide from those who attempt suicide, but also between recent and distant suicide attempters. Impaired interoception may be important for engaging in serious self-injury; thus, reestablishing one's connection to the body may aid in the prevention of suicidal behavior.
