DESCRIPTION (provided by applicant): As one of the top three leading causes of death among teenagers and young adults, suicide has become an issue of increasing public health concern. Hopelessness has been identified as a cognitive risk factor for suicidal thinking and behavior, but the precise ways of thinking through which hopelessness arises and through which it leads to suicidal thoughts and behaviors is not well understood. This proposal for a SCORE Research Advancement Award seeks to fill this gap in the literature by 1) identifying differences in how two different subtypes of rumination prospectively predict suicidal ideation among previous suicide attempters and non- attempters, 2) examining rumination about the future as another type of process through which individuals develop hopelessness, along with modeling a procedure through which these thoughts might be changed; and 3) examining the specific cognitive content characteristic of hopeless that predicts risk for future suicidal thoughts and behavior. These aims will be addressed via a longitudinal study of a sample of young adults - screened for a history of suicidal ideation and attempts - who complete a battery of cognitive measures over 6, 12, and 18 months. Data will be analyzed via mixed model regression to examine the pathways through which two verbal-linguistic forms of rumination lead to suicidal ideation and behavior. These data will also be analyzed via multi-level modeling to examine whether rumination about the future - assessed with a newly- developed measure - is a procedure through which depressive predictive certainty and hopelessness develop. To examine the third aim, this study will utilize a cognitive fluency paradigm to test the hypothesis that young adults with reduced cognitive fluency in expecting positive future outcomes, along with certainty about an absence of positive outcomes -- are at increased risk of future suicidal ideation and attempts. Finally, individuals with and without a history of suicidal ideation or attempts will be trained to mentally rehearse making optimistic future-event predictions, to determine whether inducing optimistic future expectations leads to reduced depressive predictive certainty and hopelessness among individuals with a history of suicidality. PUBLIC HEALTH RELEVANCE: This research will contribute to the understanding of thinking processes that result in suicidal behavior. In addition, it has implications for the assessment and treatment of suicidality.

描述（由申请人提供）：作为青少年和年轻人中排名前三的主要死亡原因之一，自杀已成为公共卫生越来越关注的问题。绝望已被确定为自杀思维和行为的认知危险因素，但是尚不能够很好地理解出绝望的精确思维方式以及导致自杀的思想和行为。这项分数研究进步奖的这一提议旨在通过1）来填补文献中的这一空白，以确定在以前的自杀式示威者和非义务中的两种不同的反省亚型的差异，前瞻性预测自杀的观念，2）审查对未来的反省，这是个人发展的另一种类型的过程，以及在哪些过程中发展出了希望，以及这些方法可能会通过这些思想进行建模，从而改变了这些方法。 3）检查绝望的特定认知内容特征，以预测未来自杀思想和行为的风险。这些目标将通过对年轻人样本的纵向研究来解决 - 筛选了自杀念头和尝试的历史 - 他们完成了6、12和18个月的认知度量。数据将通过混合模型回归分析，以检查两种口头语言形式的反省形式导致自杀意念和行为的途径。这些数据还将通过多层次建模分析，以检查对未来的反思（以新开发的度量评估）是否是一种抑郁的预测性确定性和绝望的程序。为了检查第三个目标，这项研究将利用认知流利性范式来检验以下假设：预期积极的未来结果的认知能力降低的年轻人，以及对缺乏积极结果的确定性 - 正在增加未来的自杀念头和尝试的风险。最后，有或没有有自杀念头或尝试史的个人将接受培训，以进行精神上的练习，以进行乐观的未来事实预测，以确定诱导乐观的未来期望是否会导致具有自杀史的人的抑郁预测确定性和绝望。 公共卫生相关性：这项研究将有助于理解导致自杀行为的思维过程。此外，它对自杀性的评估和治疗具有影响。
