Abstract

BACKGROUND: Parkinson's disease (PD) is a common neurodegenerative disorder that impacts a person's fitness to drive. Practitioners require a sensitive and predictive battery of clinical tests to identify at-risk drivers.

PURPOSE: This study aimed to identify clinical predictors and their optimal cut points, sensitivity, specificity, and predictive values of on-road outcomes in drivers with PD.

METHOD: Participants ( N = 101) underwent a comprehensive driving evaluation. We identified predictors of pass/fail outcomes through logistic regression and computed optimal cut points through receiver operating characteristic curves and corresponding Youden indexes.

FINDINGS: The Trail Making Test Part B (Trails B; sensitivity =.89, specificity =.74; positive predictive value [PPV] =.71; negative predictive value [NPV] =.91) and contrast sensitivity (sensitivity =.82, specificity =.63; PPV =.61; NPV =.84) emerged as significant predictors. The optimal cut point for the Trails B was 108 s (area under the curve =.86). IMPLICATIONS: Occupational therapists can benefit from implementing Trails B and contrast sensitivity screening as part of in-office screening of potentially at-risk drivers with PD.
