title: Behavioral and cognitive impulsivity in obsessive-compulsive disorder and eating disorders.
abstract: This study compared self-reported impulsivity and neurocognitively assessed response inhibition in obsessive-compulsive disorder (OCD), eating disorder (ED), and healthy control participants. Participants completed the Barratt Impulsiveness Scale (BIS-11), stop-signal reaction time task, and measures of OCD and ED symptomatology (Yale-Brown Obsessive-Compulsive Scale and Eating Disorders Examination-Questionnaire). Compared to controls, both clinical groups reported higher levels of impulsivity on the BIS-11 however; only the OCD demonstrated increased stop-signal reaction time. Heightened levels of self-reported impulsivity may reflect the experience of anxiety in both OCD and ED populations whereas a lack of inhibitory control may represent a specific behavioral deficit in OCD.
