SF36.jl is a simple instrument for SF36V1 scoring.
What is SF36V1 scoring used for?
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and an abbreviated variant of it, the SF-6D, is commonly used in health economics as a variable in the quality-adjusted life year calculation to determine the cost-effectiveness of a health treatment. The original SF-36 stemmed from the Medical Outcome Study, MOS, which was conducted by the RAND Corporation. SF36 Version 1 - is a free instrument.

New version: SF12 scoring included.
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). 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). The scores may be reported as Z-scores (difference compared to the population average, measured in standard deviations). The United States population average PCS-12 and MCS-12 are both 50 points. The United States population standard deviation is 10 points. So each 10 increment of 10 points above or below 50, corresponds to one standard deviation away from the average.
The version shown here corresponds to the SF-12 version 1.0. This version of the SF-12 is non-proprietary, and the scores calculated are in reference to the United States population profile at the time of the original publication in 1994. Subsequent updates to the SF-12 have been made that align the scores with more recent U.S. demographics. However, these updates are proprietary, unlike the original SF-12. Although differences in scores between different scoring systems for the sf-12 may be minor, clinicians and researchers should note the version of the SF-12 they are using.
