A pilot study was done to evaluate criterion-related validity and test-retest reliability of the Chronic Respiratory Disease Questionnaire (CRQ). The CRQ examines how chronic obstructive pulmonary disease (COPD) effects quality of life, and evaluates four dimensions: dyspnea, fatigue, emotional function, and mastery. The pilot study did not establish validity. One of the dimensions, mastery, did not correlate with any of the criterion instruments. Reliability was demonstrated when the instrument was retested after 9 days. The recommendation, based on this research, is that the CRQ may be useful in clinical settings, but not for research.
开展了一项试点研究，以评估慢性呼吸系统疾病问卷（CRQ）的标准关联效度和重测信度。CRQ调查慢性阻塞性肺疾病（COPD）如何影响生活质量，并评估四个维度：呼吸困难、疲劳、情绪功能和掌控感。该试点研究未确立效度。其中一个维度，即掌控感，与任何标准工具均无相关性。在9天后对该工具进行重新测试时，证明了其信度。基于这项研究的建议是，CRQ可能在临床环境中有用，但不适用于研究。
