That is certainly a concern, but the 'capture by psychiatry' isn't a single sided process, many disciplines are happy to 'off load' their more problematic patient groups to psychiatry. Gastroenterology started hiving off IBS to CBT practitioners 20 years ago (sort of swap for stomach ulcer sufferers) and any patient who is unco-operative enough not to respond to Rheumatology, Neurology and even Orthopaedics treatments risks getting a one way somatisation ticket to psychiatry. Capture by psychiatry is only possible because of ejection, rejection or indifference by other disciplines, and that ejection, rejection or indifference also impacts negatively upon research efforts. If change is wanted (I assume we are all agreed that is the case) then there is no choice but to pursue a campaign for increased research funding, and the question becomes whether classification is a fundamental element to that campaign, or whether it's a side issue which detracts from the primary focus; my argument is that it's a distraction, or indeed is even worse because it places the campaign(s) for research funding in an unnecessarily oppositional context.

More funding for cohorts from the local phone book? I disagree more ridiculous research isn't needed. At this point, what matters is forcing the CDC et al in tightening up the definition to clearly articulate who has what. The wastebasket must be emptied.
