SF-12 Physical and Mental Component Scores
Dear UKHLS support,
Hope you are well.
I am currently working on a research looking at the longitudinal association between volunteering and wellbeing. I would like to use the SF-12 physical and mental component scores from UKHLS data. I have been reading the Stata do-file which shows how these 2 scales were derived, and was wondering if they were generated using means and standard deviations from the general United States population? If so, would this affect the analysis?
The link of the do-file can be found here: https://www.understandingsociety.ac.uk/sites/default/files/downloads/documentation/mainstage/syntax/stata/stata-sf12-dv-public.do
Please do correct me if I misunderstand the syntax.
