Since then, the effort has taken off like wildfire. More than 10,000 people have signed the petition, and the fledgling Coalition for DSM-5 Reform has mushroomed to include 41 concerned mental health organizations in the United States, Britain and Denmark.
Now, the Coalition has posted an open letter calling upon the developers of the Diagnostic and Statistical Manual of Mental Disorders to submit controversial proposals in the DSM-5 to an independent group of scientists and scholars with no ties to either the DSM-5 Task Force or the American Psychiatric Association for an independent, external review.
"We respectfully ask that you not respond again with assurances about internal reviews and field trials because such assurances, at this point, are not sufficient," says the letter. "We believe an external, independent review is critical in terms of ensuring the proposed DSM-5 is safe and credible."
As the critics gain ground and the battle heats up, it will be very interesting to see how the beleaguered DSM-5 Task Force responds.
