The SGRQ-I contains 34 items from the original SGRQ that are the most reliable for measuring health-related quality of life in patients with IPF. A systematic statistically-based method was used to revise the original SGRQ and develop an IPF-specific version, the SGRQ-I. Both the reliability and validity of the SGRQ-I are acceptable and comparable to the original SGRQ. A new scoring algorithm was developed that places SGRQ-I scores on a scale with the original SGRQ.
