This software calculates scores derived from the St George’s Respiratory Questionnaire (SGRQ) and the SGRQ-C. The SGRQ has been validated in COPD, asthma, and several other respiratory diseases. The SGRQ-C has been developed using COPD data, and has not yet been validated for other diseases, but is likely to perform similar to SGRQ.

Both questionnaires have three components: Symptoms (quantifying distress due to respiratory symptoms), activity (the effect of disturbances to mobility and physical activity), and impact (psychosocial impact of disease). A total score provides a global estimate of the respiratory health. The scoring range from 0 to 100 for each component, where a higher number is indicative of poorer health. For the SGRQ, a four unit change has been established as clinically relevant.
