Bulimia nervosa (BN) is a distressing condition. Its pathogenesis is not fully understood. Neurocognitive functioning, and particularly inhibitory control, is a potential biomarker that may improve our understanding of BN. A few small-scale studies have used the classical Stroop Colour Word Test (SCWT) in BN with contradictory findings. We examined SCWT performance in a large sample of people with BN (N=72), eating disorder not otherwise specified — bulimic type (N=43) and healthy controls (N=50). The results found no difference between groups on Stroop interference effect. These findings question the utility of the classical SCWT as an assessment tool in examining executive functioning in BN.
