DESCRIPTION (provided by applicant): Suicide is a leading cause of death in the United States. Thus, it can rightfully be viewed as a public health problem. Unfortunately, the prevention of suicide has proven to be a difficult task, which is likely due to the fact that much remains unknown. Joiner's (in press) interpersonal-psychological theory of attempted and completed suicide proposes that there are three factors that are both necessary and sufficient for an individual to have the desire and ability to complete suicide: perceived burdensomeness, thwarted belongingness, and the acquired ability to engage in acts of self harm. The proposed project will test portions of the third factor of the theory (i.e., the acquired ability to engage in acts of self harm) by conducting three studies. The first study will explore factors (i.e., previous experience with painful stimuli) that differentiate those who complete suicide from those who attempt suicide. The second study will examine how impulsivity relates to pain tolerance, a factor posited to contribute to the ability to engage in lethal suicidal behavior. The third study will investigate gender differences in mood lability and how these differences facilitate exposure to painful stimuli, thereby conferring additional risk for suicide.

描述（由申请人提供）：自杀是美国的主要原因。因此，它可以正确地被视为一个公共卫生问题。不幸的是，预防自杀已被证明是一项艰巨的任务，这可能是由于许多事情仍然未知。乔纳（正在出版）关于企图自杀和完成自杀的人际心理学理论提出，对于一个人来说，想要有自杀的欲望和能力，必须具备三个必要且充分的因素：感知到的负担、受挫的归属感以及获得的能力。从事自残行为。拟议的项目将通过进行三项研究来测试该理论的第三个因素的部分内容（即获得的进行自残行为的能力）。第一项研究将探讨区分完成自杀者与企图自杀者的因素（即以前经历过痛苦刺激）。第二项研究将探讨冲动与疼痛耐受性之间的关系，疼痛耐受性被认为是导致致命自杀行为能力的因素。第三项研究将调查情绪不稳定性的性别差异，以及这些差异如何促进暴露于痛苦的刺激，从而增加自杀的风险。
