Validity of the Cognitive Behavioral Driver’s Inventory in Predicting Driving Outcome

This article reports on an historical cohort study undertaken to compare Cognitive Behavioral Driver’s Inventory (CBDI) scores for clients who passed and failed a driving evaluation and who are in different diagnostic groups (left cerebrovascular accident [CVA], right CVA, traumatic brain injury [TBI], and cognitive decline). The study also aimed to determine sensitivity, specificity, and positive and negative predictive values of the CBDI, to compare validity of the CBDI with other tools, and to identify factors associated with outcome. All participants (n = 172) completed a driving evaluation; their diagnoses were as follows: 28 with left CVA, 20 with right CVA, 58 with TBI, 23 with cognitive decline (Alzheimer’s disease, early dementia, undiagnosed cognitive defects), 25 with other cerebral vascular disease, 7 with multiple sclerosis, and 11 with other neurological disorders (such as Parkinson’s disease, meningitis, tumors, Guillain-Barre syndrome). The results showed that mean CBDI and motor-free visual perception tests (MVPT) scores were significantly worse for those who failed the driving test, compared to those who passed the driving evaluation. Sensitivity of the CBDI was 62%, specificity was 81%, positive predictive values were 73%, and negative predictive values were 71%. The authors conclude that the CBDI is not sufficiently predictive of outcome to replace a driving evaluation. The CBDI is predictive only for clients with right CVA and TBI. Thus drivers with cognitive problems should be evaluated using tests that are appropriate for their individual diagnosis.
