French‐Canadian Version of the Chronic Respiratory and of the St George′s Respiratory Questionnaires: An Assessment of their Psychometric Properties in Patients with Chronic Obstructive Pulmonary Disease

Abstract

The present study confirms that the French-Canadian translated versions of the CRQ and the SGRQ perform well with respect to their psychometric properties. They are both suitable for their intended purpose, ie, to detect change in health status in patients with COPD when assessing if a treatment is beneficial. However, the symptoms domain of the SGRQ cannot be used to assess acute change with respect to a given therapy.
