The SGRQ is a 50-item questionnaire with 76 weighted responses. It provides a Total score and three component scores: Symptoms (distress caused by respiratory symptoms), Activity (physical activities that cause or are limited by breathlessness), and Impacts (social and psychological effects of the disease). The Total score and each of the SGRQ sub-scores are scored from 0 to 100 where 0 indicates best and 100 indicates worst health. An increase in score indicates worsening health. A change in the Total score of 4 units is consistent with a clinically significant change in the subject

The Acute SF-12v2 is self-administered by patients, and completed on average in 2 minutes or less.
