Evidence that repetitive negative thinking (RNT) is a shared feature of a number of disorders has prompted the need for transdiagnostic self-report instruments; that is, measures of RNT that can be administered to individuals irrespective of their diagnosis. The Repetitive Thinking Questionnaire (RTQ; McEvoy et al., 2010) was developed to meet this need, and its psychometric properties and capacity to predict psychopathology have been tested in undergraduate and clinically anxious samples.
We administered the RTQ to currently depressed (n = 29), formerly depressed (n = 61) and never-depressed (n = 93) community participants.
The RTQ demonstrated good psychometric properties, with excellent internal consistency for the RNT subscale (α=.93) and good convergent validity with measures of negative affect and psychopathology symptoms (rs= .47-.61). In addition, and in accord with our predictions, currently depressed and recovered depressed participants reported more RNT than never-depressed participants, but currently and recovered depressed participants did not differ. In addition, RNT scores explained additional variance in depression and anxiety symptoms, after controlling for gender, age, neuroticism, state negative affect, and intolerance of uncertainty.
Our sample was drawn from the community but participants were not treatment-seeking, and we employed a cross-sectional design.
Taken together with previous experimental and longitudinal studies, our results support the utility of addressing RNT in the treatment and prevention of relapse in depression. Moreover, these data confirm the utility of the RTQ as a brief, transdiagnostic self-report measure of RNT.
重复消极思维（RNT）是许多障碍的共同特征，这一证据促使人们需要一种跨诊断的自我报告工具；也就是说，无论个体的诊断如何，都可以使用 RNT 的测量方法。重复思维问卷（RTQ；McEvoy 等人，2010 年）就是为了满足这一需求而开发的，其心理测量学特性和预测精神病理学的能力已经在大学生和临床焦虑样本中得到了检验。
我们向当前抑郁（n=29）、曾抑郁（n=61）和从未抑郁（n=93）的社区参与者发放了 RTQ。
RTQ 表现出良好的心理测量学特性，RNT 分量表具有极好的内部一致性（α=.93），与负面情绪和精神病理学症状的测量具有良好的聚合效度（rs=.47-.61）。此外，与我们的预测一致，当前抑郁和已恢复抑郁的参与者报告的 RNT 比从未抑郁的参与者多，但当前抑郁和已恢复抑郁的参与者之间没有差异。此外，在控制性别、年龄、神经质、状态负性情绪和不确定性容忍度后，RNT 得分解释了抑郁和焦虑症状的额外方差。
我们的样本来自社区，但参与者不是寻求治疗的，而且我们采用了横断面设计。
结合以前的实验和纵向研究，我们的结果支持在抑郁症的治疗和预防复发中解决 RNT 的有效性。此外，这些数据证实了 RTQ 作为一种简短的、跨诊断的 RNT 自我报告测量工具的有效性。
