This study aims to examine the responsiveness of these tools by severity of dyspnoea category in patients with COPD. Forty-nine COPD patients who underwent a 12-week pulmonary rehabilitation (PR) programme were assessed at baseline, 12 weeks and at 28-week follow-up. Patients were categorized into two groups by severity of dyspnoea category (i.e. mild to moderate (modified Medical Research Council (mMRC) 1\u20132) and severe to very severe (mMRC 3\u20134)) using the mMRC dyspnoea scale. Effect size (ES) was computed as estimates of responsiveness. The SGRQ demonstrated greater responsiveness by total sample (SGRQ, ES = 0.87; CAT, ES = 0.75) and for the mMRC 3\u20134 category (SGRQ, ES = 0.91; CAT, ES = 0.76) on completion of PR. At 28-week follow-up, overall comparable responsiveness of the CAT and SGRQ was identified by total sample (SGRQ, ES = 0.75; CAT, ES = 0.74) and by severity of dyspnoea category. The symptom, impact and activity domains of the SGRQ showed good responsiveness, with greater ESs obtained overall for the mMRC 3\u20134 category. On completion of PR, the SGRQ demonstrates a greater responsiveness with COPD patients, especially in relation to the mMRC 3\u20134 category, while both the CAT and SGRQ show comparable responsiveness on follow-up.<\/jats:p>","DOI":"10.1177\/1479972317694622","type":"journal-article","created":{"date-parts":[[2017,3,15]],"date-time":"2017-03-15T08:06:48Z","timestamp":1489565208000},"page":"352-359","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Health status of COPD patients undergoing pulmonary rehabilitation: A comparative responsiveness of the CAT and SGRQ"],"prefix":"10.1177","volume":"14","author":[{"given":"Anabel","family":"Sciriha","sequence":"first","affiliation":[{"name":"Department of Physiotherapy, Faculty of Health Sciences, University of Malta, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Lungaro-Mifsud","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, Faculty of Health Sciences, University of Malta, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josianne","family":"Scerri","sequence":"additional","affiliation":[{"name":"Department of Mental Health, Faculty of Health Sciences, University of Malta, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosalie","family":"Magro","sequence":"additional","affiliation":[{"name":"Department of Medicine, Mater Dei Hospital, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liberato","family":"Camilleri","sequence":"additional","affiliation":[{"name":"Department of Statistics and Operations Research, Faculty of Science, University of Malta, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Montefort","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine and Surgery; University of Malta, Msida, Malta"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,3,15]]},"reference":[{"issue":"1","key":"bibr1-1479972317694622","first-page":"2","volume":"8","author":"Chan-Yeung M","year":"2004","journal-title":"Int J Tuberc Lung Dis"},{"key":"bibr2-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(04)16855-4"},{"key":"bibr3-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1136\/thoraxjnl-2013-203808"},{"key":"bibr4-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(07)61380-4"},{"key":"bibr5-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1378\/chest.110.4.896"},{"key":"bibr6-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7525-1-5"},{"key":"bibr7-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201204-0596PP"},{"key":"bibr8-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/145.6.1321"},{"issue":"3","key":"bibr10-1479972317694622","first-page":"286","volume":"24","author":"Kaltsakas G","year":"2011","journal-title":"Pneumon"},{"key":"bibr12-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1053\/rmed.2003.1488"},{"key":"bibr13-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1023\/A:1022280532276"},{"key":"bibr14-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1053\/rmed.2000.0976"},{"key":"bibr15-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1186\/1465-9921-11-79"},{"key":"bibr16-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00177210"},{"key":"bibr17-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2466-12-20"},{"key":"bibr18-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.98.12020363"},{"key":"bibr19-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(99)07042-7"},{"key":"bibr20-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1136\/thx.42.10.773"},{"key":"bibr21-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-4356(01)00407-3"},{"issue":"5","key":"bibr22-1479972317694622","first-page":"557","volume":"20","author":"Jones G","year":"2009","journal-title":"Int Uro gynec J"},{"key":"bibr23-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1080\/165019701750165916"},{"key":"bibr24-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1177\/1479972310393756"},{"key":"bibr25-1479972317694622","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2008.01.019"},{"key":"bibr26-1479972317694622","first-page":"A4515","volume-title":"B109.
