Dear list,
I am looking for literature about critical appraisal of questionnaire
surveys especially for the problems with non-respondents (nonresponse
bias).
I've heard that the JAMA only accepts surveys with a response-rate of >=
60%. But I could not find such a minimum rate in the literature
(searched 3 survey research textbooks and 2 clinical epidemiology
textbooks).
Three questions:
Is there any evidence for such a minimum rate or is it "only" a
convention like a p-value of 0,05?
If it is a convention is anyone aware of refernces about it?
Is such a minimum rate reasonable?
best regards
Sven Trelle
