The SF-12 is a self-reported outcome measure assessing the impact of health on an individual's everyday life. It is often used as a quality of life measure. The SF-12 is a shortened version of it's predecessor, the SF-36, which itself evolved from the Medical Outcomes Study. The SF-12 was created to reduce the burden of response. Two summary scores are reported from the SF-12 – a mental component score (MCS-12) and a physical component score (PCS-12).
