title: Situation awareness in obsessive-compulsive disorder.
abstract: Past studies have suggested that OCD patients suffer memory impairment on tasks using complex stimuli that require memory for combined elements to be maintained, but not for more simplistic memory tests. We tested this with 42 OCD patients and 42 healthy controls performed a computerized situation awareness task. In addition, participants completed the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and Maudsley Obsessive-Compulsive Inventory (MOCI). The OCD patients had poorer accuracy in integration/comprehension and perception levels than controls. There were significant correlations between situational awareness scores (i.e., visuo-spatial monitoring and processing) and Y-BOCS obsession-compulsion and slowness and doubt scores of MOCI in OCD patients. In addition, there were also significant correlations between situational awareness and controlling, cleaning, slowness, rumination and total scores of MOCI in control group. Results indicated that (I) OCD patients have problems of perception, integration, and comprehension of complex visual perceptions; (II) situation awareness deficits associated with severity and prevalence of obsessions and compulsions.
