The interpersonal-psychological theory of suicide posits that elevated pain tolerance is necessary to engage in suicidal behaviour. It is assumed that suicidal intent only leads to lethal (or near lethal) suicide attempts when an individual has the capability to persist the pain involved in dying. The aim of this study was to assess whether objective pain persistence moderates the association between suicide intent and lethality of a recent suicide attempt. Ninety-seven inpatients, who were hospitalized due to a recent suicide attempt, were interviewed regarding lifetime suicide attempts as well as their most recent suicide attempt: Method of attempt, intention to die, medical risk of death, probability of an intervention, and physical condition following the attempt were inquired. Pain persistence was examined using a pressure algometer. Contrary to the expectation, pain persistence did not moderate the association between suicide intent and lethality of a recent suicide attempt, that is, medical risk of death, probability of an intervention, or physical condition following the attempt. Future studies are needed to examine method specific pain persistence for suicidal behaviour in a longitudinal study design.
自杀的人际关系-心理理论假设，提高疼痛耐受度是进行自杀行为所必需的。人们认为，只有当一个人有能力忍受死亡带来的痛苦时，自杀意图才会导致致命（或接近致命）的自杀企图。本研究旨在评估客观的疼痛持续时间是否会调节自杀意图与最近自杀企图的致命性之间的关联。97 名因最近自杀企图而住院的患者接受了关于他们一生的自杀企图以及最近一次自杀企图的访谈：尝试的方法、死亡意图、死亡的医疗风险、干预的可能性以及尝试后的身体状况。使用压力测痛计检查疼痛持续时间。与预期相反，疼痛持续时间并没有调节自杀意图与最近自杀企图的致命性之间的关联，即死亡的医疗风险、干预的可能性或尝试后的身体状况。未来的研究需要在纵向研究设计中，检查自杀行为的特定方法的疼痛持续时间。
