calculation of the degree to wh ich two independent clinicians could agree on a diagnosis (us-

cians on two separate ratings of cross-cutting symptoms, pers onality traits, disability, and
diagnostic severity meas ures (using intraclass correlation coefficients) along with information
on the precision of these estimates of reliabilit y. It was also possible to assess the prevalence
rates of both DSM-IV and DSM-5 conditions  in the respective clinical populations.
The routine clinical practice field trials in volved recruitment of individual psychiatrists
and other mental health clinicians. A volunteer  sample was recruited that included gener-
alist and specialty psychiatrists, psychologists, licensed clinical social workers, counselors,
marriage and family therapists , and advanced practice psychiatric mental health nurses.

sures to a wide range of clinicians to assess their feasibility and clinical utility. 
Public and Professional Review
In 2010, the APA launched a unique Web site to  facilitate public and professional input into
DSM-5. All draft diagnostic criteria and prop osed changes in organization were posted on
www.dsm5.org for a 2-month co mment period. Feedback totaled more than 8,000 submis-
sions, which were systematically reviewed by each of the 13 work  groups, whose members,
where appropriate, integrated questions and comments into discussions of draft revisions
and plans for field trial testing. After revisions to the initial draft criteria and proposed
chapter organization, a second posting occurred in 2011. Wo rk groups considered feedback
from both Web postings and the results of th e DSM-5 Field Trials when drafting proposed
