Abstract:
DSM-5 moved OCD out from under the Anxiety Disorder section, into a new category: Obsessive Compulsive and Related Disorders and added two new specifiers. Specifically a modification of one specifier (insight) and the addition of a new tic specifier. DSM-5 redefined obsessions and recognizes the importance of avoidance and thought stopping beyond compulsions as other strategies to deal with obsessions. OCD related disorders include: Trichotillomania, Hoarding Disorder, Skin Picking Disorder, and Body Dysmorphic Disorder.
