This randomized controlled trial extends our prior DOD funded study “Efficacy of a Driving Program on Safe Community Mobility for Combat Veterans” conducted 2011-2016.  In this effectiveness study, we seek to examine how well the findings of the efficacy study are replicable to a larger population of combat veterans. Our core aim is to discern the effectiveness of a simulator-based Occupational Therapy Driving Intervention (OT-DI) as compared to traffic safety education. Our aims seek to address if the OT-DI improves fitness-to-drive abilities and results in reduced driving errors as measured on a driving simulator over the short term (post intervention) and intermediate term (3 months post). We will also examine impact on real-world driving as measured by proxy report and (for a sub-group of participants) an assessment of on-road driving.
