We sought to determine whether the partial administration of the
Cognitive Behavioral Driver's Inventory (CBDI) has a significant effect on its
concurrent validity. METHOD: Data were extracted from charts of clients with
cerebrovascular accident or traumatic brain injury from three centers. The CBDI
was administered either completely or partially (right and left perimetry or
Wechsler Adult Intelligence Scale-Revised (WAIS-R; Wechsler, 1982; Picture
Completion and Digit Symbol tests were not completed). Concurrent validity
indicators were calculated for the CBDI and three different scenarios of partial
administration of the CBDI. RESULTS: Only 52% of the road test failures were
predicted correctly by the completely administered CBDI. Nonadministration of the
WAIS-R rarely modified the CBDI results. Omission of perimetry scores tended to
increase the sensitivity and decrease the specificity (not significantly).
CONCLUSION: The CBDI should be used as a complement, not a substitution, for a
road test. Partially administrating the CBDI, specifically excluding perimetry measures, can affect its concurrent validity.
