Article describes the background and development of the Spinal Cord Injury -- Quality of Life (SCI-QOL) measurement system, a spinal cord injury (SCI)-specific, patient-reported outcome measure of health-related quality of life (HRQOL) covering physical, emotional, and social domains of functioning. The SCI-QOL was developed using item response theory (IRT) and comprises 22 subdomains that include 19 IRT-calibrated item banks and 3 fixed-length scales measuring physical, emotional, and social aspects of HRQOL. Its design ensures that each item is relevant to individuals with SCI. Each item bank may be administered as a full bank, short form, or computer adaptive test, while scales may be administered in fixed-length format only.
