    Crawley et al.
    Unfortunately, questionnaire based from a general purpose survey, so at best would be an interesting screen to use before contacting the patients and following them up to see if they have CFS. This was not done, nor were the questions specific to CFS. At best perhaps an upper bound on those who have fatigue and some other symptoms.


    The prevalence of 2.6% seems rather high, though the case definition is a hell of a lot better than '6 months medically unexplained fatigue'.
    As an exclusion 'the adolescent felt better after resting' seems to partially capture PEM and non-restorative sleep.

    The lack of support they find for the central sensitisation hypothesis is interesting - as I understand it this is one of the keystones of BPS.
    (everything is felt more than it should, so fear/avoidance kick in)

    The diagnosis of CFS was based on a questionnaire for "measuring psychiatric disorders" (see link). There is no mention of medical investigation.

    Seeing as it's not a proper study, and any science/statistics/reporting will have been done most improperly, that's the best way to read it. I won't be properly reading it either.

    Me neither.

    This stuff is nonsense.

    Not science.

    Don't waste your time...

    Happy Christmas.

    "Future research should investigate whether depression and anxiety are causal or secondary to CFS and whether anxiety is causal for chronic pain syndrome. Furthermore, it is important to elucidate the factors that are contrib- uting to the higher prevalence of CFS, and to a greater degree, CWP, observed in women [/QUOTE]


    You could think the NICE criteria were developed especially for people like Crawley to endlessly approach CFS from a MH/behavioural perspective

    I agree. Maybe they used looser cut-offs than normal for other things?

    Thanks for pointing that out interesting.

    Think we can guess these won't be the factors that cause higher prevalence in autoimmune illness?

    Seems strange that no prospective data was analysed? Or perhaps that is the plan - current data to predict future CFS in 5-10 years time.

    A medical examination is mandatory for diagnosing CFS according to Fukuda, NICE or Canadian criteria - all of them. It's mandatory because there are so many possible alternative causes of fatigue that you can't find with a questionnaire. So this study tells us nothing useful about CFS, however defined. Publish it as a chronic fatigue study perhaps, but researchers and journals shouldn't use the CFS label without proper CFS diagnosis.

    That doesn't sound like M.E to me, sounds more like chronic fatigue, yet another case of diluted definitions, typical Esther Crawley.

    It's only asking about the past 7 days, so it wouldn't even qualify as vaguely being "chronic".

    I guess on reflection (first post edited) that this would be a reasonable upper bound on CFS in the population.
    But not an actually useful one, as nobody thinks it's that high.

    I think I'd just assumed there must be something to indicate more long-standing problems! If it really is just about the last seven days, that's ridiculous.

    Sounds more to me like confused teenagers being asked if they slowed down near their bedtime a bit or switched of a bit during a boring lesson or were recovering from a sports event the previous day.

    Its a really serious problem this, being tired leading up to bedtime 3 days out of seven. Thank goodness people like Crawley are on the case, we need to throw as much money at this as possible whilst ignoring neuro immune diseases.

    A lot of the research I am seeing here is like this, this one seems to be bordering on 'social science', very sad

    " Furthermore, it is important to elucidate the factors that are contrib- uting to the higher prevalence of CFS, and to a greater degree, CWP, observed in women " most likely natural selection, you know that basic principle of science ?
