    I'm figuring this is not really an outcome as such, just a report on what the "normal" bounds are on these scales at the present time. For use when deciding whether any given individuals or subset are outside normal bounds.

    Because obviously, these are self-report tools, so they don't measure absolute rates of anything, only how people rank their own experience relative to some internal mental model. And the way we self-assess, the mental models we construct and use as "standards" and the way we compare ourselves to others are all factors that are influenced by society and culture.

    It reminds me a bit of the claim that "the incidence of dyslexia in school-age children is an alarming 10%". Alarming indeed. But if you define dyslexia as scoring in the bottom 10% of readers in a particular age group on a particular assessment, then the rate will of course be around 10%. That's how you've set it in the first place.

    A low response rate seems to be a real issue in research that tries to select a representative sample of the general population:

    Maybe I am being dim but I am surprised by the absence of any reference in the abstract to the huge increase in percentage in the female 18-29 group. Does this mean they do not think it is reliable? And does that imply that none of it is reliable? Or what?
