PY - 2019 T2 - Current Diagnosis & Treatment: Psychiatry, 3e AB - Obsessions are unwanted aversive cognitive experiences usually associated with feelings of dread, loathing, or a disturbing sense that something is not right. The individual recognizes (at some point in time) that these concerns are inappropriate in relation to reality and will generally attempt to ignore or suppress them. Compulsions are overt behaviors or covert mental acts performed to reduce the intensity of the aversive obsessions. They may occur as behaviors that are governed by rigid, but often irrelevant, internal specifications. They are inappropriate in nature or intensity in relation to the external circumstances that provoked them.
