BACKGROUND: French versions of the Chronic Respiratory Questionnaire (CRQ) and the St George's Respiratory Questionnaire (SGRQ) have largely been used in Canada, although the process by which they were translated remains unknown and the psychometric properties of these translated versions have not been assessed in a properly designed study. OBJECTIVE: To translate and evaluate the psychometric properties of the French-Canadian versions of the CRQ and the SGRQ. METHODS: The questionnaires were translated according to standardized guidelines for cross-cultural adaptation. Measurements were made at baseline and again after two weeks in 27 chronic obstructive pulomonary disease (COPD) patients known to have stable disease. Measurements were also taken pre-and post-treatment in patients with acute exacerbation of COPD (33 patients) or in pulmonary rehabilitation (32 patients). RESULTS:The CRQ showed high test-retest reliability (the majority above 0.70), although it was slightly lower for the dyspnea dimension (0.58 to 0.65). The SGRQ also showed high test-retest reliability (above 0.80), although it was lower for the symptoms dimension (0.54 to 0.58). The internal consistency reliability coefficients ranged from 0.73 to 0.90 for the CRQ and above 0.80 for the SGRQ, except for the symptoms dimension. The Pearson's correlation coefficients were low (less than 0.30) between most of the translated questionnaire dimension scores and forced expiratory volume in 1 s, 6 min walking test and dyspnea measures. The correlation was generally high (greater than 0.50) between the two questionnaires and the 36-item short form health survey, and for those domains that measured the same construct. The changes in the total and subscale scores of the CRQ and the SGRQ (except for the symptoms domain) were all largely above the variability of the score in the stable disease group. CONCLUSION: The present study confirms that the FrenchCanadian 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. RÉSULTATS : Le CRQ a montré une bonne fiabilité de test-retest (audessus de 0,70 dans la plupart des cas), même si celle-ci était légèrement inférieure (0,58-0,65) à l'égard de la dyspnée. Le SGRQ a aussi montré une bonne fiabilité de test-retest (au-dessus de 0,80), même si celle-ci était légèrement inférieure (0,54-0,58) à l'égard des symptômes. Les coefficients de cohérence interne variaient entre 0,73 et 0,90 pour le CRQ et ils se tenaient au-dessus de 0,80 pour le SGRQ, sauf en ce qui concerne les symptômes. Les coefficients de corrélation de Bravais-Pearson étaient faibles (inférieurs à 0,30) entre la plupart des résultats des différents aspects dans les questionnaires traduits et le volume expiratoire maximal par seconde, l'ép...

“…At 6 months postoperatively, quality of life was evaluated with the St. George's respiratory questionnaire (SGRQ) [3]. The survey questionnaire consists of 50 questions, covering three aspects, which involve respiratory symptoms of cough, sputum, chest distress, etc.…”

“…Based on the patients' preferences and surgeons' experience, 22 and 68 patients subsequently underwent LVRS by thoracotomy and VATS, respectively. The diagnoses of COPD in all the patients were made utilizing commonly employed criteria [3]. The demographics of the patients in both groups showed no significant difference (P>0.05) ( Table 1).…”

The aim of this study is to evaluate the safety and efficacy of lung volume reduction surgery (LVRS) by videoassisted thoracoscopic surgery (VATS) in the treatment of chronic obstructive pulmonary disease (COPD). A total of 90 patients with COPD from 2002 to 2012 were enrolled into our study, comprising 22 who underwent conventional thoracotomies and 68 VATS. Pulmonary function testings, arterial blood gases analysis, and quality of life between these two groups were compared. VATS was found to be superior to the conventional thoracotomy in terms of length of hospital stay, intraoperative blood loss, intubation time, volume of chest tube drainage, and postoperative pain assessment (P<0.05). However, significant differences in pulmonary function testings, arterial blood gases analysis, 6-min walking distance (6-MWD), and postoperative quality of life between the two groups were not found (P>0.05). LVRS by VATS is a safe and reliable surgical approach for the treatment of COPD, with less invasiveness and shorter hospital recovery time.

“…The ADO index may be more practical, 168 and the DOSE index has been developed in primary care and intended for use in routine clinical practice. 169 A number of validated questionnaires measuring dyspnoea, 170,171 COPD control, 172,173 and impact on quality of life [174][175][176] International and national guidelines summarise and make therapeutic recommendations based on the extensive pharmacological and pulmonary rehabilitation evidence base. 143,[145][146][147][148] and the IPCRG guidelines for COPD management provide a primary care perspective.…”
