Executive Function Index (EFI) performance and risk factors for disordered eating.

We examined Executive Function Index (EFI) performance in individuals at risk (n=22) for an eating disorder, based on the SCANS criteria. In comparison to those not at risk (n=104; also based on the SCANS criteria), those at risk on SCANS were more likely to be depressed, anxious, and showed deficits in many components of EFI performance, including EFI impulse control and EFI total score. These results support previous work on executive function in those at risk for an eating disorder and highlight the use of the EFI as a tool for such investigation in this population.
