To prevent suicidal behaviors, it is crucial to understand the mechanisms and processes that enable an individual to act on suicidal thoughts. Suicide capability, which involves an increased pain tolerance and fearlessness of death, is a critical factor that enables an individual to endure the physical pain necessary to make a lethal suicide attempt (Joiner, 2005; Klonsky & May, 2015). Extant research has largely conceptualized suicide capability as developing linearly in response to painful and provocative experiences, but the emerging literature on the temporal dynamics of suicide has been challenging the notion of linearity in suicide risk. Few studies have directly measured and compared changes in suicide capability in response to rumination on different affective states. We sought to experimentally test if rumination in the context of low vs. high arousal emotions will prompt distinct changes in two core components of suicide capability: pain tolerance and fearlessness of death on two undergraduate student samples. In both studies, participants provided measures of subjective emotional state as well as pain threshold, tolerance, and persistence before and after completing experimental manipulations which included both emotion and rumination induction procedures. In the second study, measures of fearlessness about death and physiological arousal (heart rate) were added to the experimental procedures. We found significant decreases in pain threshold, tolerance, and persistence following the experimental manipulations but found no main effects of rumination or suicide risk. These findings suggest that suicide capability can fluctuate but these changes may occur through a different mechanism and/or differ between individuals at varying levels of suicide risk.

测试自杀能力是否具有动态倾向:情感和唤醒对自杀能力瞬时波动的作用

为了防止自杀行为,了解使个人能够对自杀念头采取行动的机制和过程至关重要。自杀能力,包括增强的疼痛耐受性和对死亡的无畏,是一个关键因素,使个人能够忍受进行致命的自杀企图所必需的身体疼痛(Joiner,2005 年;Klonsky & May,2015 年)。现有的研究在很大程度上将自杀能力概念化为对痛苦和挑衅性经历做出反应的线性发展,但关于自杀时间动态的新兴文献一直在挑战自杀风险的线性概念。很少有研究直接测量和比较针对不同情感状态的沉思而导致的自杀能力变化。我们试图通过实验测试在低唤醒情绪和高唤醒情绪的背景下沉思是否会促使自杀能力的两个核心组成部分发生明显变化:对两个本科生样本的疼痛耐受性和对死亡的无畏。在这两项研究中,参与者在完成包括情绪和反刍诱导程序在内的实验操作前后提供了主观情绪状态以及疼痛阈值、耐受性和持久性的测量值。在第二项研究中,对死亡和生理唤醒(心率)的无所畏惧的措施被添加到实验程序中。我们发现实验操作后疼痛阈值、耐受性和持久性显着降低,但没有发现反刍或自杀风险的主要影响。
