Abstract

Neurocognition in bulimia nervosa (BN) is under-researched. This study investigated aspects of attention (d2-Letter Cancellation Task), inhibitory control (Stroop and go/no-go task), and decision making (Game of Dice Task) in 40 people with BN, 30 with eating disorder not otherwise specified-BN type (EDNOS-BN), and 65 healthy controls (HCs). The National Adult Reading Test (NART) and Depression Anxiety Stress Scale (DASS-21) were also administered. Analyses of covariance (covariates: age, NART, and DASS-21) showed that people with BN and EDNOS-BN performed as well as HCs on all tasks. Attention task performance was poorer in the EDNOS-BN than in the BN group.
