What is a good score for the SF-12?
Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning [27]. A score of 50 or less on the PCS-12 has been recommended as a cut-off to determine a physical condition; while a score of 42 or less on the MCS-12 may be indicative of ‘clinical depression’ [27].
What is SF-12 mental component summary?
SF-12 Mental Component Summary (MCS). This measure converts valid answers to the origin questions into a single mental functioning score, resulting in a continuous scale with a range of 0 (low functioning) to 100 (high functioning).
What is the SF-12 questionnaire?
Instrument. The SF-12v2 is a health-related quality-of-life questionnaire consisting of twelve questions that measure eight health domains to assess physical and mental health. Physical health-related domains include General Health (GH), Physical Functioning (PF), Role Physical (RP), and Body Pain (BP).
How is VR 12 scored?
As with PROMIS Global Health, VR-12 scores are standardized using a T-score metric with a mean of 50 and a standard deviation of 10.

Compared with the SF-36, the SF-12 has only one or two items from each of the eight health concepts of the SF-36. The SF-12 items allow the calculation of the PCS (PCS-12) and MCS (MCS-12) scales but not of the subscales.
How do you calculate MCS and PCS?
PCSc was then constructed by multiplying each SF-36 scale z-score by its respective physical factor scoring coefficient and summing the eight products. Similarly, MCSc was created by multiplying each SF-36 scale z-score by its respective mental factor score coefficient and summing the products.
How is quality of life score calculated?
The QOLS is scored by adding up the score on each item to yield a total score for the instrument. Scores can range from 16 to 112. There is no automated administration or scoring software for the QOLS.

How is the SF-12 score calculated?
The SF-12 contains 12 items which yield a physical health component score and a mental health component score. These scales are computed following a 4-step algorithm (46), transformed to a range of possible values from 0 to 100, higher values corresponding to higher perceived quality of life.
What does SF-12 stand for?
The 12-item Short Form Survey (SF-12) is a general health questionnaire that was first published in 1995 as part of the Medical Outcomes Study (MOS). The SF-12 was constructed using questions drawn from each of the 8 dimensions of the MOS 36 item Short Form Survey (SF-36).
What is the PCs and MCs score on the SF-12?
The SF-12 scoring manual also indicates that for U.S. residents between the ages of 45 and 54, the mean PCS score is 49.71 (std. dev. 9.5) and the mean MCS score is 50.45 (std. dev. 9.55). NLSY respondents in 2008 have higher MCS scores than the overall population and similar PCS scores.
How is the SF-12 constructed?
The SF-12 was constructed using questions drawn from each of the 8 dimensions of the MOS 36 item Short Form Survey (SF-36). It is designed to have similar performance to the SF-36, while taking less time to complete. Two summary scores are reported from the SF-12 – a mental component score (MCS-12) and a physical component score (PCS-12).
