Given that suicide is a leading cause of death worldwide, there has been considerable research on theories of suicide risk. Despite the volume of such research, each theory is largely investigated in isolation and there has been little attempt to integrate them. Thus, the goal of the present study is to integrate two theories of suicide risk, Alloy and Abramson's hopelessness theory of suicide (HT) and Joiner's interpersonal psychological theory of suicide (IPTS), into one mediational model where the effects of the risk associated with the HT variables (i.e., a negative cognitive style) on suicidal ideation are transmitted by the IPTS (i.e., perceived burdensomeness and thwarted belonging) variables. Participants were 245 young adults with elevated levels of depressive symptoms who completed self-report measures of suicide risk at baseline and a measure of suicidal ideation eight weeks later. The results of a mediated model supported our hypothesis. The effects of the HT variables on suicidal ideation were mediated by the IPTS variables. Furthermore, results did not support the reverse model, suggesting specificity of the direction of our hypotheses. These findings imply that there may be merit in attempting to integrate theories of suicide risk rather than studying them in isolation.
鉴于自杀是全球主要的死亡原因之一，人们对自杀风险理论进行了大量研究。尽管此类研究数量众多，但每种理论大多是单独进行研究的，几乎没有尝试将它们整合起来。因此，本研究的目的是将两种自杀风险理论——阿洛伊和阿布拉姆森的自杀绝望理论（HT）以及乔伊纳的人际自杀心理理论（IPTS）——整合到一个中介模型中，在该模型中，与HT变量（即消极认知风格）相关的风险对自杀意念的影响通过IPTS变量（即感知到的负担感和归属感受挫）来传递。研究参与者为245名抑郁症状水平较高的年轻人，他们在基线时完成了自杀风险的自我报告测量，并在八周后完成了一次自杀意念测量。中介模型的结果支持了我们的假设。HT变量对自杀意念的影响通过IPTS变量进行中介。此外，结果不支持反向模型，这表明我们假设方向的特异性。这些发现意味着尝试整合自杀风险理论而非单独研究它们可能是有价值的。
