| Brief Description |
The SGRQ is a self-administered 50-item questionnaire that measures the quality of life in patients with airway obstruction diseases. It contains two parts and covers three domains (symptoms, activity, and impacts). The SGRQ assesses respiratory symptom frequency and severity as well as activity and social function impairments due to respiratory symptoms. |
| Number of Items | 50 items |
| Range | 0-100 (percentage) |
| Responses options/scale |
No |
| Developed for | Research, Clinical practice |
| PRACTICAL APPLICATION | |
