The study is on internet usage

For this journal there is a 400-word, 5-reference limit to e-letters
or otherwise I would have written more.

Dear AK Knudsen

I note that in the discussion section, 3rd paragraph, 9th line the
authors acknowledge that a previous study had shown that multiple
sclerosis had a higher online activity than me/cfs.

"The results from this study are in line with findings from Davison et
al.,20 who found CFS to have the second highest level of online
activity, after multiple sclerosis."

Why then did the authors design a study that did not include multiple
sclerosis as a comparison? Especially as the authors have concluded
that me/cfs has ten times the relative online activity of any other
disorder or condition.

Do the authors think that by not including multiple sclerosis as a
comparison to me/cfs, they were achieving best practise for a
scientific study? I note also that there is not mention of this matter
as being a weakness in their study.

Since the authors have acknowledged a possibility that online activity
for multiple sclerosis may be higher than for me/cfs, do the authors
think that the possible explanations for this high activity is the
same for both illnesses.

Do the authors consider a possible explanation for people with
multiple sclerosis having a high online activity, is due to being
isolated with a debilitating physical illness, loneliness and seeking
companionship. I note these possible explanations were not listed for
the high online activity of me/cfs people.

RE: Comparison of chronic fatigue syndrome/myalgic encephalopathy with

Knudsen and colleagues raise an interesting issue. However, I believe
they could have helped ensure better matching by using other groups of
patients with chronic illnesses such as multiple sclerosis which, as
the authors highlighted, had previously been found to have higher
online activity than Myalgic encephalomyelitis/chronic fatigue
syndrome (ME/CFS). Perhaps in time the field will develop and
statistical tools like regression could help isolate which independent
variables predict online activity, and hence help isolate communities
with unusual patterns.

It would have been interesting if the authors had gathered qualitative
information on the topics discussed, to see if there were differences
not just in the quantity of activity but also in terms of the range of
topics discussed, and how they were discussed in different groups.
ME/CFS is often said to be a heterogeneous condition (1); similarly in
my experience, users of ME/CFS online forums are not all the same in
terms of their interests (what they like to discuss or read about).
This can be seen in the different types of groups that show up in a
search of www.yahoogroups.com, for example: there are chat groups;
groups interested in experimental therapies; groups interested in
activism of one sort or another; groups interested in discussing
research findings, etc.

The authors suggest that the high level of activity in ME/CFS could be
explained by action proneness (2). However that study was
retrospective and thus could be affected by recall bias. Research that
utilised an "action proneness" questionnaire, when individuals were
actually ill with ME/CFS, found lower levels compared to the general
population (1).

The paper also mentions the "boom-bust" theory with regard to activity
levels in ME/CFS. However, there is evidence that activity levels in
ME/CFS patients don't fluctuate any more than control groups (3,4).

We are told that "research on support group participation for CFS/ME
sufferers indicates that active members report greater symptom
severity and less improvement of the disorder than inactive members
(5)". However the study, which also involved fibromyalgia, found that
employment rates, an important measure of overall functioning was not
statistically different between the two groups.

If there are particular issues in ME/CFS that are driving patients to
internet forums, perhaps in time they will improve e.g. the
stigmatisation mentioned. Also, more effective therapies for ME/CFS
may become available - currently there are no FDA approved drugs for
the condition, which can lead patients to be interested in numerous
speculative therapies.

The author makes a good point that those of us who are homebound and isolated are using the internet for companionship.  We're not being depressed and avoiding other people, we've found a way to bring other people to where we are.  I couldn't go out to meet people, so I made new friends online; people who don't judge me based on stereotypes. 
 
These new friends know, without long complicated explanations, what I'm dealing with and why I can't just pop out for a bottle of milk when I need it.  No criticism about laziness -- when I admit the only thing I got done all day was a load of laundry, I get cheers for having felt well enough to do the whole process in one day, not strip the bed on Monday, carry it to the laundry room on Tuesday, put it in the washer on Wednesday....  When you're as sick as we are, you need someone to cheer your smallest accomplishments, not some healthy person to scoff that she cleaned her whole house, did 14 loads of laundry and still had the energy to take an aerobics class and spend 3 hours at the mall.
 
Maybe the reason active members have greater symptom severity is the cause, not the result, of greater online activity.  We're too sick to work, so we have more time to participate in internet groups.  We have symptoms so bad that we're not able to live with them, so we have more reason to look for treatments.  Personally, I spent more time on CFS sites when I'm really sick, and less time on them when I'm functioning well enough to work, because work takes away from the time I can spend online.
