Over at a Yahoo! Groups, http://health.groups.yahoo.com/group/Tinnitus
A graduate student, Melinda S. Morgan from Carleton University, Canada,
has just asked the group to undertake an internet based survey about
their experiences with Tinnitus. She is a MS candidate in the Dept of
Pyschology.
She has had T since she was a teenager. I see no reason why she would
not like to invite ppl in this ng. I will ask her to post an invitation
here.

She was kind enough to publish in the 'files' section of the Yahoo!
group, a paper she did in her undergraduate work on Tinnitus. It is
good reading, focusing on the 'positive attitude' aspects of
successfully dealing with T.  Her current survey will be a follow-up on
her previous work.  What I'd like to mention here is that, in the
Psychology sciences, internet based surveys have become accepted and
even embraced.  Here is a quote from Melinda's 2002 paper.

"Other potential limitations relevant to the use of an Internet based
survey include the limited type of data available and the
sample characteristics. For instance, we were not able to directly
assess tinnitus severity using state of the art acoustic instruments.
Nor were we in a position to obtain behavioral data on coping.
Although the demographic and general characteristics of a sample
that is obtained online versus in the community may at first appear
as an issue regarding the Internet sampling method, we see it as a
potential strength because of the diverse sample of people the
study was able to include. Some had had tinnitus for less than 6
months, whereas others reported that they had had tinnitus for
more than 50 years. Some were from communities without access
to necessary specialists. In fact, the sheer size of the sample that
we obtained is one of this study's strengths because it gave us the
power to detect interaction effects. With respect to our study, we
concur with Krantz and Dalal (2000), who have shown that not
only do Internet studies tend to draw larger samples than those
obtained from the community but that these samples are also more
heterogeneous and in this sense may be more representative than
their community-based counterparts."

Research led me to his website at the University of Hanover.

This website contains dozens, if not hundreds, of ongoing and completed
surveys on various topics.

In addition, here is a link to a page describing a very informative
book by Edited by Michael H. Birnbaum, "Psychological Experiments on
the Internet". Check out all the links at the bottom of the page.
