Using an IADL assessment to identify older adults who need a behind-the-wheel driving evaluation

Occupational therapists need to routinely assess driving ability in hospital and/or rehabilitation settings. The purpose of this study is to determine if the Assessment of Motor and Process Skills (AMPS), an observational tool of instrumental activities of daily living, could discriminate between older adult drivers who pass, pass with restrictions, or fail a behind-the-wheel (BTW) evaluation. Forty-six participants were evaluated with a BTW driving assessment and the AMPS. Two one-way ANOVAs found significant differences for both the motor and process scores suggesting the AMPS can be used as a screening tool for driving. Results also showed no significant difference in age between those participants who passed, failed, or needed restrictions supporting the concept that driving abilities are related more to function, not age. Exploration of minimum scores is discussed.
