Health status measurement: sensitivity of the self-reported Chronic Respiratory Questionnaire (CRQ-SR) in pulmonary rehabilitation
Open accessAbstract
BACKGROUND: A self-reported CRQ (CRQ-SR) has recently been developed and found to be a reproducible and reliable measure of health status. This study explores both the sensitivity of the CRQ-SR and relative sensitivity compared with the conventional interviewer led CRQ (CRQ-IL) in patients undergoing pulmonary rehabilitation. METHODS: Eighty patients with stable chronic obstructive pulmonary disease who had been referred for pulmonary rehabilitation completed the CRQ-SR at initial assessment and at the end of the 7 week programme. A further 35 patients completed both the CRQ-SR and the CRQ-IL, administered 1 week apart, before starting rehabilitation and again at the end of the programme. RESULTS: There were large statistically and clinically significant changes in mean score per dimension following rehabilitation in all dimensions of the CRQ-SR (dyspnoea mean difference 0.87 (95% CI 0.61 to 1.14); fatigue 0.76 (0.53 to 1.0); emotion 0.60 (0.35 to 0.86); mastery 0.76 (0.52 to 1.0); p<0.001). Similar results were found in the comparison of the sensitivity of the CRQ-SR and the CRQ-IL, with large changes in mean score per dimension following rehabilitation for both versions of the questionnaire (p<0.005). No significant differences were seen in the magnitude of change between the two formats of the questionnaire (p>0.05). CONCLUSION: The self-reported CRQ is as sensitive to change as the interviewer led CRQ in patients undergoing pulmonary rehabilitation but has the advantage of being less time consuming to administer.

The Chronic Respiratory Questionnaire-Self reported is a valid and reliable measure of health status in patients with COPD.
“The CRQ-SR is a self-reported measure of health status shown to be a valid and reliable in patients with COPD [32].”
From Can we identify patients with different illness schema following an acute exacerbation of COPD: A cluster analysis (2014) · cites this paper as [32]
The Abstract describes the CRQ-SR as a reproducible and reliable measure of health status, and the Discussion finds it sensitive to change in patients with COPD undergoing pulmonary rehabilitation. Our copy does not establish its validity more broadly, so the validity part of the claim is not supported. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
