    I thought it was interesting as it:
    (i) gives some examples of the bias
    (ii) shows that some studies actually try to control for it.

    Given the amount of questionnaires that are used in ME/CFS research, this may have some relevance.

    Doesn't Chalder think that CFS patients are particularly prone to distortions driven by consideration of social desirability (underpinning her working linking it to anorexia?)

    I doubt she'd bring it up in this regard.

    Afraid I haven't read that paper so will leave it to others to answer.

    Basically what the authors are referring to is individuals not truthfully answering questionnaires on a wide variety of things, which is a slightly different issue from people feeling some sort of social pressure to act/think/whatever in a certain way but where their answers to questions are what they really think/feel/is really the way they behave.

    SDR is also known as "faking good."

    Well designed questionnaires will have sub-scales built into them that assess SDR.

    In a broader context, the process of properly validating an instrument (such as a set of questions used for a diagnostic criteria for a specific disorder - such as the ICC) is time consuming, expensive and it requires a significant background in the appropriate statistical methods. Look what happened with the Reeves definition, a ten-fold increase in the number of "CFS" patients. I'm hoping that Lenny Jason wasn't a co-author of the ICC because he wanted to independently validate it and not because he didn't feel comfortable with it.
