This script implements the RAND 36 - Item Health Survey 1.0 version of the Medical Outcomes Study (MOS) Short Form Health Survey (SF-36). It was developed at RAND as part of MOS. It differs from the commercially available MOS SF-36 in the scoring algorithm. The following articles/webpages were used to develop this script:
Ware, J., Jr., & Sherbourne, C.D. (1992). The MOS 36-Item Short-Form Health Survey (SF-36): I. Conceptual Framework and Item Selection. Medical Care, 30, 473-483.
Ware, J.E. Jr. & Gandek, B, (1998). Overview of the SF-36 Health Survey and the International Quality of Life Assessment (IQOLA) Project. Journal of Clinical Epidemiology, 51, 903-912.
More information (including scoring guidelines) about the RAND 36 - Item Health Survey 1.0 on: https://www.rand.org/health/surveys_tools/mos/mos_core_36item.html
