Abstract

fitness to drive neuropsychological assessment cognitive flexibility executive functioning
Mental processes responsible for goal-oriented behavior – executive functioning (EF) – include working memory, flexible thinking, and cognitive control. A reliable and valid assessment of EF can inform appropriate interventions and decisions to drive. We investigated the feasibility and validity of a short, iPad-administered EF screening tool in a non-clinical sample: the Coffs Harbour Executive Functioning Screen (CHEFS). Participants (N = 55) completed the CHEFS alongside a neuropsychological assessment of EF used to assess fitness to drive. Discriminant function analysis (DFA) showed that the CHEFS correctly classified 87% of participants to normative clinical ranges on the Verbal Fluency Test. The results suggest that CHEFS is a novel, easily administered tool for assessing EF in a non-clinical sample. DFA is an appropriate within-tool analysis to support the widespread administration of a screening tool to determine fitness to drive and classify patient referral needs. Further assessment is required to determine CHEFS reliability and validity with a broader range of participants varying in neuropsychological functioning, age, ethnicity, test experience, and compared to on-road driving performance.
