Σύνοψη	The SGRQ is a 76-item disease-specific quality-of-life instrument designed to measure health status in patients with chronic respiratory disease, particularly chronic obstructive pulmonary disease (COPD). Developed by Jones and colleagues at King's College London in 1991, it has become the gold standard for assessing functional impact and symptom burden in respiratory populations. The SGRQ is widely used in clinical trials, epidemiological studies, and routine respiratory care to track changes in patient-reported outcomes.	The CRQ is a 20-item, four-domain questionnaire developed by Guyatt and colleagues at McMaster University in 1987 to measure health-related quality of life specifically in patients with chronic respiratory disease, particularly chronic obstructive pulmonary disease and cystic fibrosis. Uniquely, the CRQ can be administered by interview or self-report, and its four domains (dyspnea, fatigue, emotional function, mastery) directly address the multidimensional burden of chronic respiratory disease. The CRQ has demonstrated exceptional responsiveness to pulmonary rehabilitation and other interventions, making it a preferred outcome measure in respiratory research and clinical practice.
