Can anyone give me some insight as to whether it is okay to modify the
wording of the SF-36 in phone survey? We are doing an outcomes study in
which we are using the SF-36 as our measurement tool. The baseline data is
collected on site from the patient as they read and answer the survey.
However, there is such a low response rate for follow-up data that we are
resorting to calling to collect the follow-up data. However, we fear that
some of the questions are so lengthy that the patient will tune out. Is it
okay to shorten the questions and state in the protocol that we have
modified the survey? I am concerned that the baseline measurement won't be
valid against the follow-up because of different methods of collection.
