Accumulating evidence suggests that repetitive negative thinking (RNT) is a transdiagnostic phenomenon. However, various forms of RNT such as worry, rumination, and post-event processing have been assessed using separate measures and have almost exclusively been examined within the anxiety, depression, and social phobia literatures, respectively. A single transdiagnostic measure of RNT would facilitate the identification of transdiagnostic maintaining factors of RNT, and would be more efficient than administering separate measures for each disorder. Items from three existing measures of RNT were modified to remove diagnosis-specific content and administered to a sample of undergraduate students (N=284). Exploratory factor analysis yielded two factors labeled Repetitive Negative Thinking and Absence of Repetitive Thinking (ART). The RNT scale demonstrated high internal reliability and was associated with anxiety, depression, anger, shame, and general distress. Moreover, the RNT scale was associated with constructs that are theoretically related to engagement in RNT, including positive and negative metacognitions, cognitive avoidance, thought suppression, and thought control strategies. The ART scale had little predictive utility. Theoretical and clinical implications are discussed.
越来越多的证据表明，重复性消极思维（RNT）是一种跨诊断现象。然而，各种形式的 RNT，如担忧、沉思和事件后处理，都是使用单独的测量方法进行评估的，并且几乎只在焦虑、抑郁和社交恐惧症文献中分别进行了研究。单一的 RNT 跨诊断测量方法将有助于确定 RNT 的跨诊断维持因素，并且比为每种疾病分别使用单独的测量方法更有效。从三种现有的 RNT 测量工具中修改了一些项目，以去除特定于诊断的内容，并对一组本科生（N=284）进行了测试。探索性因素分析得出了两个因子，分别标记为重复性消极思维和无重复性思维（ART）。RNT 量表表现出较高的内部可靠性，并与焦虑、抑郁、愤怒、羞耻和一般痛苦有关。此外，RNT 量表与理论上与从事 RNT 相关的构念有关，包括积极和消极的元认知、认知回避、思维抑制和思维控制策略。ART 量表的预测效用不大。讨论了理论和临床意义。
