TI  - Evaluating the Clinical COPD Questionnaire: A systematic review.
PG  - 251-262
LID - 10.1111/resp.12970 [doi]
AB  - The Clinical COPD Questionnaire (CCQ) is recommended by the Global Initiative for 
      Chronic Obstructive Lung Disease (GOLD) to evaluate health status in patients 
      with COPD. The objective of this work was to systemically assess the reliability, 
      validity, responsiveness and minimum clinically important difference (MCID) of 
      the CCQ. A structured search was conducted in three databases to identify 
      articles that evaluated the psychometric properties of the CCQ in individuals 
      with COPD. Two investigators screened the title, abstract and full text of the 
      articles to determine study eligibility and performed the data extraction. 
      Quality assessment of included studies was assessed by the COSMIN 
      (Consensus-Based Standards for the Selection of Health Measurement Instruments) 
      checklist. Finally, 43 studies were included, over half of which had fair 
      methodological quality. Internal consistency (reliability) of the CCQ total score 
      ranged from 0.84 to 0.94, and test-retest reliability was 0.70-0.99. The overall 
      CCQ had a better correlation with St George's Respiratory Questionnaire (SGRQ; 
      from 0.71 to 0.88) and COPD Assessment Test (CAT; from 0.64 to 0.88) than 
      modified Medical Research Council (mMRC; from 0.392 to 0.668) and forced 
      expiratory volume in 1 s (FEV(1) % predicted; from -0.31 to -0.68). Scores were 
      different within GOLD stages, groups, composite events and co-morbidities. CCQ 
      was sensitive to exacerbations, pulmonary rehabilitation and smoking cessation 
      with the MCID of 0.4. The CCQ is a very useful and practical tool that can be 
      used in clinical populations with good reliability, validity and responsiveness 
      to interventions.
