About the score:

The Veterans RAND 12 Item Health Survey (VR-12) was developed from the Veterans RAND 36 Item Health Survey (VR-36) which was developed from the MOS RAND SF-36 Version 1.0. It was designed to replicate much of the behavior of the VR-36 with a reduced number of questions.

The results of the VR-12 are summarized as two scores – a Mental Component Score (MCS) and a Physical Component Score (PCS). The scores may be reported as Z-scores (difference compared to the population average, measured in standard deviations). The United States population average PCS and MCS are both 50 points. The United States population standard deviation is 10 points. Therefore, each increment of 10 points above or below 50 corresponds to one standard deviation away from the population average.

The VR-12 is in the public domain and there is no charge for its use. The score developers request acknowledgement for its use as they outline on their website their website. Subsequent updates to the VR-12 scoring have been made to align the scores with more recent U.S. demographics. This updated scoring is available from the score developer. Although differences in scores between different scoring systems for the VR-12 may be minor, clinicians and researchers should note the version of the VR-12 they are using.
