Most in the field of psychology, especially practicing clinicians, overwhelmingly object to DSM 5 and thousands of petitions were ignored. The public should be aware that NO ONE is allowed to APPLY to be a member of the task force. Resumes are discarded. The task force is 100% APPOINTED by a very few people with very special interests. Over 70% of this appointed task force have financial ties to Big Pharma. Big Pharma was only directly involved (the CEO of Glaxo/Smith/Klein) in getting Restless Leg to be named a mental disorder to help get their new drug Rx'd more frequently. However, Big Pharma was indirectly involved in many ways.
Practicing clinicians were NOT appointed to the task force. The psychology and counseling community objected to this problem (and to the DSM 5 problems in general) in the thousands and they were ignored. The task force has absolutely 0% interest in how the 5 impacts clinical practice, billing and insurance issues, etc. (this was actually quoted at a conference by a DSM historian). They seem to care a great deal about how it impacts medication prescriptions. With 80% of psychiatric medications being Rx'd by primary care physicians, this makes the loosening of the criteria in 5 even more unsettling. Only 20% of psychotropics are Rx'd by psychiatrists. From what I have gathered so far, their only objective (i.e., the task force) was to explain behavior in a way that made the case to expand diagnostic criteria. There were several on the task force with the noble objective of capturing the underserved population, which is needed, but the politics and special interests have now led to what will result in at least 20% of the population being diagnosable as opposed to the 2-3% who were diagnosable in the DSM IV.
IMO, the DSM 5 problems can largely be attributed to group think, private industry and special interests allowed to run amok, and confirmation biases leading the task force to overwhelmingly ignore research that would have made the 5 a much better manual.
Of course, like everyone else, there is much more to learn and see before drawing any final opinions, but these are my thoughts on the negatives thus far. My opinion is subject to evolve as we all learn more. And, like I said, there is some really good stuff in 5. It is a shame al the bad is so bad that the good is hard to see.
