Interrater reliability of Western University's on-road assessment.
BACKGROUND
Little empirical support exists for interrater reliability between evaluators from different backgrounds when assessing on-road outcomes of drivers.


PURPOSE
We quantified interrater reliability of on-road outcomes between a certified driving school instructor (DI) and an occupational therapist and certified driver rehabilitation specialist (CDRS).


METHOD
Both raters used the Global Rating Score (GRS) with two levels (pass, fail), the GRS with four levels (pass, pass with recommendations, fail remediable, fail), and the priority error rating score (PERS; most frequently occurring on-road errors in priority order) to assess 35 drivers (age, M = 48.31 years, SD = 9.76 years; 40% male; 86% with multiple sclerosis).


FINDINGS
The DI and occupational therapist CDRS had excellent agreement on the GRS with two levels (κ = .892, p < .0001), GRS with four levels (κ = .952, p < .0001), and the PERS (κ = .847-.902, p < .0001), indicating interrater reliability.


IMPLICATIONS
This research contributes to empirical support for the on-road assessment.
