783Conditions for
Further Study
Proposed criteria  sets are presented fo r conditions on which future research is en-
couraged. The specific items, thresholds, and durations contained in these research crite-
ria sets were set by expert co nsensus—informed by literature review, data reanalysis, and
field trial results, where available—and are intended to provide a common language for
researchers and clinicians who are interested in  studying these disord ers. It is hoped that
such research will allow the field to better  understand these conditions and will inform
decisions about possible placement in fort hcoming editions of DSM. The DSM-5 Task
Force and Work Groups subjecte d each of these proposed crit eria sets to a careful empir-
ical review and invited wide commentary from the field as well as from the general public.
The Task Force determined that there was in sufficient evidence to warrant inclusion of
these proposals as official mental disorder diagnoses in Section II. These proposed criteria
sets are not intended for clinical use; only th e criteria sets and disorders in Section II of
DSM-5 are officially recognized and can be used for clinical purposes.
