背景了解面向未来的重复思维--即反复考虑一个人的未来是否会出现积极或消极的结果--如何导致与绝望相关的认知，可能会阐明预测未来在抑郁症状和自杀意念中的作用。这项研究考察了未来事件流畅性和抑郁预测确定性--即做出悲观的未来事件预测的倾向--作为解释面向未来的重复思维、抑郁症状和自杀念头之间关系的机制。方法对因自杀意念或未遂历史而过度抽样的年轻人(N=354)，完成了悲观的面向未来的重复思维(即人们认为未来将发生负面结果或积极结果不会发生的程度)、未来事件流畅性、抑郁预测确定性、抑郁症状的基线测量，结果积极的面向未来的重复思维预测6个月后抑郁的预测性确定性，部分通过较低的积极未来事件流畅度而不是增加的消极未来事件流畅性来调节。悲观的面向未来的重复思维与6个月的自杀意念严重程度之间存在间接关系，通过6个月的抑郁症状通过6个月的抑郁预测确定性，也通过6个月的抑郁症状(但不是抑郁的预测确定性)。局限性缺乏实验设计限制了对因果关系的推断，而且以女性为主的样本可能限制了性别的概括性。结论临床干预应该解决悲观的面向未来的重复思维-及其对人们如何容易地思考积极的未来结果的影响-作为减少抑郁症状和间接自杀意念的一种潜在方法。
BackgroundKnowing how future-oriented repetitive thought – i.e., repeated consideration of whether positive or negative outcomes will happen in one's future – leads to hopelessness-related cognitions may elucidate the role of anticipating the future in depressive symptoms and suicide ideation. This study examined future-event fluency and depressive predictive certainty – i.e., the tendency to make pessimistic future-event predictions with certainty – as mechanisms explaining the relation between future-oriented repetitive thought, depressive symptoms, and suicide ideation.MethodsYoung adults (N= 354), oversampled for suicide ideation or attempt history, completed baseline measures of pessimistic future-oriented repetitive thought (i.e., the degree to which people consider whether negative outcomes will happen or positive outcomes will not happen in their futures), future-event fluency, depressive predictive certainty, depressive symptoms, and suicide ideation severity and were followed up 6 months later (N= 324).ResultsPessimistic future-oriented repetitive thought predicted depressive predictive certainty at 6-months, partially mediated by lower positive but not increased negative future-event fluency. There was an indirect relationship between pessimistic future-oriented repetitive thought and 6-month suicide ideation severity via 6-month depressive predictive certainty through 6-month depressive symptoms, and also via 6-month depressive symptoms (but not depressive predictive certainty) alone.LimitationsLack of an experimental design limits inferences about causality, and a predominantly female sample may limit generalizability by sex.ConclusionClinical interventions should address pessimistic future-oriented repetitive thought – and its impact on how easily people can think about positive future outcomes – as one potential way to reduce depressive symptoms and, indirectly, suicide ideation.
