Examining the Factor Structure and Incremental Validity of the Barkley Deficits in Executive Functioning Scale - Short Form in a Community Sample.

The Barkley Deficits in Executive Functioning Scale - Short Form (BDEFS-SF; Barkley, 2011) was developed to assess deficits in five facets of executive functioning. Theoretical assumptions surrounding the BDEFS-SF presume that executive dysfunction is an overarching construct that consists of five domain-specific factors (i.e., a hierarchical model; Barkley, 2011). Prior research has supported a correlated five-factor model, but the tenability of hierarchical or bifactor models of the BDEFS-SF have not yet been tested. In the present study (N = 1,120 community adults), confirmatory factor analysis was used to compare four theoretically relevant models of the BDEFS-SF (i.e., one-factor, correlated five-factor, hierarchical, and bifactor models). The bifactor model provided the best fit to the data. However, the general factor accounted for the overwhelming majority of variance in BDEFS-SF scores and none of the domain-specific factors exhibited adequate construct replicability or factor determinancy. Further, the general factor accounted for the overhelming majority of variance in criterion variables (i.e., executive attention and health anxiety); the Organization and Emotion factors accounted for a small amount of unique variance in executive attention and the Emotion factor accounted for a small amount of unique variance in health anxiety. Taken together, study findings suggest that the BDEFS-SF has a strong general factor and independent use of the domain-specific factors is contraindicated.
