The APA is now working on the fifth version of the hefty tome, slated for publication in May 2013. Because the DSM-IV was largely similar to its predecessor, the DSM-5 embodies the first substantial change to psychiatric diagnosis in more than 30 years. It introduces guidelines for rating the severity of symptoms that are expected to make diagnoses more precise and to provide a new way to track improvement. The DSM framers are also scrapping certain disorders entirely, such as Asperger’s syndrome, and adding brand-new ones, including binge eating and addiction to gambling.
In the past the APA has received harsh criticism for not making its revision process transparent. In 2010 the association debuted a draft of the new manual on its Web site for public comment. “That’s never been done before,” says psychiatrist Darrel Regier, vice chair of the DSM-5 Task Force and formerly at the National Institute of Mental Health. The volume of the response surprised even the framers: 50 million hits from about 500,000 individuals and more than 10,000 comments so far.
