I googled standardized response means and found a whole mess of
orthopedic papers that use the term.
Here's one that defined it and gave a reference:
http://www.biomedcentral.com/1471-2474/4/10
The definition:
"Responsiveness was calculated as standardized response mean (SRM). SRM
is defined as mean score change divided by the standard deviation of
that score change [18]. An SRM >0.8 is considered large."
The reference (18) is in the paper.
