重复性消极思维（RNT）已被发现参与了几种类型的情绪问题的维持，因此被认为是一个transdiagnosis过程。然而，RNT的现有措施通常集中在一个特定的疾病特定的内容。在这篇文章中，一个内容独立的RNT自陈问卷的初步验证。在两项研究（总N = 1832）中评价了15项持续性思维问卷，包括非临床和临床参与者。验证性因素分析的结果支持一个二阶模型，一个高阶因素代表RNT一般和三个低阶因素代表（1）RNT的核心特征（重复性，侵入性，脱离困难），（2）感知的RNT的非生产性和（3）RNT捕获的心理能力。高的内部信度和高重测信度被发现的总规模和所有三个分量表。持续性思维问卷的有效性与现有的RNT措施和协会的抑郁症和焦虑症的症状水平和临床诊断的实质性相关性的支持。结果表明，新措施的实用性研究RNT作为一个transdiagnosis过程。(C)2010爱思唯尔有限公司版权所有。
Repetitive negative thinking (RNT) has been found to be involved in the maintenance of several types of emotional problems and has therefore been suggested to be a transdiagnostic process. However, existing measures of RNT typically focus on a particular disorder-specific content. In this article, the preliminary validation of a content-independent self-report questionnaire of RNT is presented. The 15-item Perseverative Thinking Questionnaire was evaluated in two studies (total N = 1832), comprising non-clinical as well as clinical participants. Results of confirmatory factor analyses across samples supported a second-order model with one higher-order factor representing RNT in general and three lower-order factors representing (1) the core characteristics of RNT (repetitiveness, intrusiveness, difficulties with disengagement), (2) perceived unproductiveness of RNT and (3) RNT capturing mental capacity. High internal consistencies and high re-test reliability were found for the total scale and all three subscales. The validity of the Perseverative Thinking Questionnaire was supported by substantial correlations with existing measures of RNT and associations with symptom levels and clinical diagnoses of depression and anxiety. Results suggest the usefulness of the new measure for research into RNT as a transdiagnostic process. (C) 2010 Elsevier Ltd. All rights reserved.
