Caroline,
Thanks for the thoughtful response! I suspect that the context of form may
play a greater role than number of fields. Applying for a loan vs. Sign in
to an instant message program.
Thanks for the lead on survey research!

Hi Brian
I don't know of any specific research on this problem in the forms arena.
There is plenty of anecdotal evidence around - just ask
anyone, frankly.
For example, in a recent thread on this list
http://www.ixda.org/discuss.php?post=27398 Sign-up experience there was
some
discussion of the pleasure given by a short, simple sign-up and the
annoyance caused by a very long one.
But I don't know of much in the way of hard facts. It would be great to
hear of anything published - let's hope someone else on the
list knows.
The survey methodologists have looked at the problem of lower response
rathers when there are more questions on a questionnaire, a
closely related area. I'm away from my library at the moment but I'm fairly
sure that Dillman would cite the relevant literature.
Most recent edition:
Mail and Internet Surveys: The Tailored Design Method 2007 Update with New
Internet, Visual, and Mixed-Mode Guide (Hardcover)
by Don A. Dillman (Author)
Another thing to think about (I don't know of the context of your question)
is that although sheer volume of questions is definitely
an issue, the relevance of those questions and the strength of the user's
interest in the topic are very important as well. There
is, believe it or not, such a thing as a form or questionnaire that is too
short - one that fails to ask the questions that the user
considers should be asked in the context of the overall purpose.
Best,
Caroline
