The 12-item Short-Form Health Survey (SF-12) is an abbreviated version of the SF-36, one of the most widely used patient-reported health outcome rating scales. Similar to the SF-36, it yields summary scores of physical and mental health (PCS and MCS, respectively). However, SF-36 derived PCS and MCS scores have not been found valid in neurological disorders such as Parkinson's disease (PD). ⋯ These observations suggest that the SF-12 can be used as a coarse health survey tool in PD and that a total SF-12 may be useful as a measure of overall health. However, its appropriateness as an outcome measure can be questioned and it is somewhat unclear exactly what the derived scores represent. As such, the SF-12 should probably be considered an assessment tool (or index) rather than a measurement instrument.
