Rumination, a transdiagnostic factor in different psychopathological conditions, is believed to be activated and sustained by dysfunctional metacognition. The Positive Beliefs about Rumination Scale (PBRS) and the Negative Beliefs about Rumination Scale (NBRS) have been used to measure the metacognitive beliefs of rumination and have been investigated in many cultural contexts. However, it remains unclear whether these scales can work as well for the Chinese population. Therefore, this study aimed to explore the psychometric properties of the Chinese versions of these scales and to test the metacognitive model of rumination for students with different levels of depression.
The PBRS and NBRS were forward-backward translated into Mandarin. In total 1,025 college students were recruited to complete a battery of web-based questionnaires. Exploratory factor analysis, confirmatory factor analysis, and correlation analysis were used to test the structure, validity, and reliability of the two scales, as well as their item correlations with rumination.
A new two-factor structure of the PBRS (rather than the original one-factor model) and a new three-factor structure of the NBRS (rather than the original two-factor model) were extracted. The goodness-of-fit indices of these two factor models showed they had a good to very good fit with the data. The internal consistency and construct validity of PBRS and NBRS were also affirmed.
The Chinese versions of the PBRS and the NBRS were generally shown to be reliable and valid, but their newly extracted structures fit the Chinese college students better than their original structures. These new models of PBRS and NBRS are of value to be further explored in Chinese population.
反刍是不同心理病理状态下的一种跨诊断因素，被认为是由功能失调的元认知激活和维持的。反刍思维正性信念量表（PBRS）和反刍思维负性信念量表（NBRS）被用于测量反刍思维的元认知信念，并在许多文化背景下进行了研究。然而，这些量表是否同样适用于中国人群尚不清楚。因此，本研究旨在探讨这两个量表的中文版的心理测量学特性，并检验不同抑郁水平学生的反刍思维的元认知模型。
PBRS 和 NBRS 被译为中文。共招募了 1025 名大学生完成一系列基于网络的问卷。采用探索性因素分析、验证性因素分析和相关分析来检验这两个量表的结构、效度和信度，以及它们与反刍思维的项目相关性。
从 PBRS 中提取出一个新的两因素结构（而不是原始的单因素模型）和从 NBRS 中提取出一个新的三因素结构（而不是原始的两因素模型）。这两个因子模型的拟合优度指数表明，它们与数据具有良好到非常好的拟合度。PBRS 和 NBRS 的内部一致性和结构效度也得到了肯定。
PBRS 和 NBRS 的中文版通常表现出可靠和有效的特点，但它们新提取的结构比原始结构更适合中国大学生。这些新的 PBRS 和 NBRS 模型在中国人群中进一步研究具有价值。
