| > The same can be said of probably most disorders listed in the DSM. True. Although, it is plausible that some DSM-5 disorders may have greater validity issues than others, and ASD may be one of those disorders with greater-than-average validity issues. The paper I cited built an extensive case, based on 14 separate research findings, to support the conclusion that ASD lacks validity. I wouldn't presume that if you repeated the same exercise for some other DSM-5 disorder you'd necessarily get an equally negative result. > The original purpose of DSM was so that psychologists and the lot have categorizations handy for filling out claims with patient's insurance. Which makes its use in research especially questionable. And this is part of why NIMH announced back in 2013 [1] that they were shifting research funding away from research based on DSM categories. If research based on the DSM-5 is dubious, then funding such research is not a good use of limited research funding resources. (It is worth noting this study was funded by NICHD not NIMH; I'd question whether NIMH would fund a study like this given its current funding criteria.) > That doesn't mean these disorders don't exist or that DSM diagnoses are invalid or useless. It just means that it's all a bit 'hand wavy'. What do you mean by "invalid"? If by "valid" one means biological validity and/or construct validity, then the whole point of the paper I cited was to argue that ASD lacks both forms of validity, and hence that in those senses of "valid", the diagnosis of ASD is invalid.
