12-Item Short Form Survey from the RAND Medical Outcomes Study

The 12-Item Short Form Health Survey (SF-12) was developed for the Medical Outcomes Study (MOS), a multi-year study of patients with chronic conditions. The resulting short-form survey instrument provides a solution to the problem faced by many investigators who must restrict survey length. The instrument was designed to reduce respondent burden while achieving minimum standards of precision for purposes of group comparisons involving multiple health dimensions.

The SF-12 is not available on the RAND Health website. Use of the SF-12 is governed by QualityMetric, which has no affiliation with RAND. RAND Health has put the following MOS short form health surveys in the public domain for non-commercial use, by posting them on the RAND Health Website:
