The metacognitions questionnaire-30 (MCQ-30) was developed for the assessment of metacognitive beliefs and processes that are central components of the metacognitive model of emotional disorders. Anxiety and depression commonly occur in patients with chronic obstructive pulmonary disease (COPD). Testing such a model for anxiety and depression in patients with COPD is warranted. However, the psychometric properties of the MCQ-30 in COPD patients are unknown. Therefore, in this study we aimed to examine these properties in COPD patients. The MCQ-30 was administered to 203 COPD patients referred to a rehabilitation unit in respiratory medicine. Confirmatory factor analysis (CFA) was used to test the five-factor as well as the bi-factor models of MCQ-30. Exploratory factor analyses were also performed. Both models did not meet the criteria for an acceptable fit on Comparative Fit Index (CFI) of 0.810 and 0.858 vs. criterion of ≥0.9, but the Root Mean Square Error of Approximation (RMSEA) criterion ≤0.08 was acceptable for both models with RMSEA = 0.074 and 0.066, respectively. The factors were mostly moderately correlated (0.41-0.58) with acceptable reliability coefficients (0.73-0.87). The exploratory factor analysis identified three of the five factors originally described in the five-factor model of the MCQ-30. These data show that the factor structure of the MCQ-30 appears to differ from that of the original instrument in COPD patients and further studies are needed to confirm its validity and reliability in this patient group.
元认知问卷30（MCQ - 30）是为评估元认知信念和过程而编制的，这些是情绪障碍元认知模型的核心组成部分。焦虑和抑郁在慢性阻塞性肺疾病（COPD）患者中很常见。在COPD患者中测试这样一个关于焦虑和抑郁的模型是有必要的。然而，MCQ - 30在COPD患者中的心理测量特性尚不清楚。因此，在本研究中，我们旨在检查COPD患者的这些特性。对203名转诊至呼吸内科康复单元的COPD患者进行了MCQ - 30测试。采用验证性因素分析（CFA）来检验MCQ - 30的五因素模型和双因素模型。还进行了探索性因素分析。两个模型在比较拟合指数（CFI）分别为0.810和0.858时均未达到可接受拟合标准（标准≥0.9），但近似均方根误差（RMSEA）标准≤0.08对两个模型是可接受的，RMSEA分别为0.074和0.066。各因素大多呈中度相关（0.41 - 0.58），可靠性系数可接受（0.73 - 0.87）。探索性因素分析确定了MCQ - 30五因素模型中最初描述的五个因素中的三个。这些数据表明，MCQ - 30的因素结构在COPD患者中似乎与原始工具不同，需要进一步研究以确认其在该患者群体中的有效性和可靠性。
