abstract="IMPORTANCE: Scanning the environment is critical for driving safety. The ScanCourse is a functional assessment that assesses a person's ability to scan the environment  for visual information while in motion. Measurement properties for the ScanCourse  have been reported; however, its predictive validity is unknown. <br><br>OBJECTIVE: To  determine the predictive validity of the ScanCourse for on-road driving performance  and establish clinical cutoff scores. <br><br>DESIGN: Retrospective chart reviews were  conducted over a 6-mo period. SETTING: Four Canadian driver rehabilitation programs. PARTICIPANTS: Charts from patients with neurological or vision conditions were  eligible if they contained ScanCourse and on-road driving evaluation results between  September 1, 2008, and August 30, 2018. Three hundred twenty-five charts were  included for analysis. OUTCOMES AND MEASURES: Area under the curve (AUC) analysis  was used to determine the predictive validity of ScanCourse scores for on-road  outcomes; cutoff scores were established by optimizing sensitivity and specificity. <br><br>RESULTS: The ScanCourse had an AUC of.702. The optimal cutoff score was 18/20 with  a sensitivity of 76.7% and a specificity of 47.1%. <br><br>CONCLUSIONS AND RELEVANCE:  Assessing the scanning abilities of at-risk drivers who intend to return to driving  after sustaining an injury can help identify safety risks and inform interventions. The ScanCourse was found to have acceptable discriminatory ability for on-road  driving performance. This study provides evidence supporting its continued use as a  screening tool to assess driver fitness with an identified optimal cutoff score for  clinical use. WHAT THIS ARTICLE ADDS: Measuring the predictive ability of the  ScanCourse assessment in relation to on-road driving performance provides  occupational therapists with an evidence-based clinical tool to assist with  screening fitness to drive among at-risk people.<p /> <p>Language: en</p>",
