You have beaten me to it - was going to suggest the same. Efficiently run busy practices rarely have time and patience for paper nonsense and will not participate. Whats left are a few die-hard enthusiasts participating because they can see benefit in such study, and the rest are navel gazers not having anything better to do than filling in forms Highly biased selection if you don't offer the OPTION of returning questionaires either electronically or in dead tree format. I f they used willingness to fill in paper forms as inclusion criterium, the study result will not be valid for the GP piopulation at large at all.
