AB 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.
