SF-12 Health Survey
The SF-12 Health Survey uses 12 items from the SF-36 Health Survey to estimate the profile of eight functional and well-being health-related quality of life (HRQOL) scales. The aggregated physical (PCS) and mental (MCS) HRQOL summary components are also estimated. The SF-12 has been shown to be reliable and valid.
