Suicidal ideation is a pervasive and painful experience that varies considerably in its phenomenology. Here, we consider how one key risk variable might inform our understanding of variation in suicidal ideation: emotion-related impulsivity, the trait-like tendency towards unconstrained speech, behaviour, and cognition in the face of intense emotions. We hypothesized that emotion-related impulsivity would be tied to specific features, including severity, perceived lack of controllability, more rapidly fluctuating course, higher scores on a measure of acute suicidal affective disturbance, and more emotional and cognitive disturbance as antecedents.
We recruited two samples of adults (Ns = 421, 221) through Amazon Mechanical Turk (MTurk), with oversampling of those with suicidal ideation. Both samples completed psychometrically sound self-report measures online to assess emotion- and non-emotion-related dimensions of impulsivity and characteristics of suicidal ideation.
One form of emotion-related impulsivity related to the severity, uncontrollability, dynamic course, and affective and cognitive precursors of ideation.
Despite limitations of the cross-sectional design and self-report measures, the current findings highlight the importance of specificity in considering key dimensions of impulsivity and suicidal ideation.
自杀意念是一种普遍而痛苦的体验，其表现形式差异很大。在这里，我们考虑一个关键的风险变量如何帮助我们理解自杀意念的变化：与情绪相关的冲动性，即在强烈情绪面前表现出言语、行为和认知不受约束的特质倾向。我们假设，与情绪相关的冲动性与特定特征有关，包括严重程度、感知到的不可控性、更快速波动的病程、急性自杀情感障碍测量得分较高，以及更多的情绪和认知障碍作为前驱症状。
我们通过亚马逊 Mechanical Turk（MTurk）招募了两个成人样本（n=421，221），对有自杀意念的人进行了过度抽样。两个样本都在线完成了经过心理测量验证的自我报告测量，以评估与情绪和非情绪相关的冲动维度以及自杀意念的特征。
一种形式的与情绪相关的冲动性与意念的严重程度、不可控性、动态过程以及情感和认知前驱症状有关。
尽管存在横断面设计和自我报告测量的局限性，但目前的研究结果强调了在考虑冲动性和自杀意念的关键维度时，特异性的重要性。
