The transdiagnostic view of repetitive negative thinking (RNT) claims that different forms of RNT are characterized by identical processes that are applied to disorder-specific content. The purpose of the study was to test whether the processes of RNT differ across major depression disorder (MDD), generalized anxiety disorder (GAD), and obsessive-compulsive disorder (OCD).
Forty-two individuals diagnosed with MDD, 35 individuals with GAD, 41 individuals with OCD, and 35 community controls were asked to think of a typical RNT episode and to rate its processes (core processes; use of mental capacity, unproductivity, abstractness, verbal quality, duration). Ratings were compared across groups using planned contrasts and analysis of variance.
All individuals with a clinical diagnosis rated the key processes of RNT and avoidance function of RNT as higher than healthy controls. There were no differences between individuals diagnosed with MDD, GAD or OCD on key processes and avoidance function of RNT.
Results are based on retrospective self-reports, which might restrict validity of the measurements.
Data support the transdiagnostic hypothesis of RNT. Transdiagnostic prevention and intervention techniques seem highly recommendable given these findings.
重复消极思维（RNT）的跨诊断观点认为，不同形式的 RNT 的特征是相同的过程，这些过程适用于特定于疾病的内容。本研究的目的是测试 RNT 的过程是否在重度抑郁症（MDD）、广泛性焦虑症（GAD）和强迫症（OCD）中存在差异。
要求 42 名被诊断为 MDD 的人、35 名 GAD 患者、41 名 OCD 患者和 35 名社区对照者思考一个典型的 RNT 发作，并对其过程（核心过程；使用心理能力、无生产力、抽象性、语言质量、持续时间）进行评分。使用计划对比和方差分析比较组间评分。
所有有临床诊断的个体对 RNT 的关键过程和 RNT 的回避功能的评分都高于健康对照组。MDD、GAD 或 OCD 患者在 RNT 的关键过程和回避功能方面没有差异。
结果基于回顾性自我报告，这可能限制了测量的有效性。
数据支持 RNT 的跨诊断假设。鉴于这些发现，跨诊断预防和干预技术似乎是非常值得推荐的。
