The Barkley Deficits in Executive Functioning Scale (BDEFS) is a multidimensional measure of executive functioning (EF). Yet, no work has validated the 20-item BDEFS short form (BDEFS-SF) among individuals at risk of EF deficits, including college students who consume alcohol. The current study evaluated the factor structure and measurement invariance of the BDEFS-SF in 867 undergraduates from 12 colleges/universities who endorsed past-month alcohol use. The bifactor model best fit the data, supporting the use of the general factor over the five subscales for measurement models, and measurement invariance was partially supported across sex assigned at birth. Four subscales were uniquely associated with alcohol use, consequences, and alcohol protective behavioral strategies. The BDEFS-SF total score appears to be a valid measure of EF among undergraduates who use alcohol
however, more research is needed to increase the clinical utility of the measure given the lack of support for the use of the subscales in measurement models.
