Field trials for newly proposed diagnostic criteria in the DSM-5 began this month. A total of 33 field trials are scheduled throughout the country, with 11 of the trials being conducted in large, academic medical settings and 22 of the trials occuring in smaller individual practices. Physicians registered with the AMA Masterfile will be randomly selected for the trials in October and November of 2010. The trials are scheduled to run through March of 2011, with a second phase of trials occurring from August to December 2011. A target print date for the updated DSM-5 is set for sometime in 2013.
