“…Recently, two driving studies used Item Response Theory to develop or evaluate driving scales: one to convert a standard on-road test to a Rasch scale and the other to develop a measure of driving confidence (Kay, Bundy, & Clemson, 2009;Kay, Bundy, Clemson, & Jolly, 2008;Myers, Paradis, & Blanchard, 2008). Neither studied safe driving from a comprehensive personvehicle-environment approach, in the driving context, to provide an entry point for occupational therapy intervention.…”

We investigated the psychometric properties of the 68-item Safe Driving Behavior Measure (SDBM) with 80 older drivers, 80 caregivers, and 2 evaluators from two sites. Using Rasch analysis, we examined unidimensionality and local dependence; rating scale; item-and person-level psychometrics; and item hierarchy of older drivers, caregivers, and driving evaluators who had completed the SDBM. The evidence suggested the SDBM is unidimensional, but pairs of items showed local dependency. Across the three rater groups, the data showed good person (³3.4) and item (³3.6) separation as well as good person (³.93) and item reliability (³.92). Cronbach's a was ³.96, and few items were misfitting. Some of the items did not follow the hypothesized order of item difficulty. The SDBM classified the older drivers into six ability levels, but to fully calibrate the instrument it must be refined in terms of its items (e.g., item exclusion) and then tested among participants of lesser ability.

“…Many of the off-road cognitive or perceptual assessments have limited evidence of reliability and validity (Unsworth, Lovell, Terrington & Thomas, 2005), and as few as 5% of driving assessors base their decisions on safety to drive on the off-road cognitive or perceptual assessments alone (Mazer et al, 1998). The on-road driver assessment component has been found to be the most important component of the comprehensive driving assessment procedure, and there is a growing body of research around the validity and reliability of these tests (Kay, Bundy & Clemson, 2009;Ponsford et al, 2008).…”

Background: The occupational role of 'driver' is highly valued. Stroke can have a significant impact on an individual's ability to drive safely. Multi-disciplinary driver assessments are conducted to assess the safety of poststroke individuals returning to driving, however, little follow-up of drivers following successful assessment has been performed. Aim: The objective of this study was to investigate whether passing a multi-disciplinary driving assessment following stroke predicted medium-to long-term safe and confident driving. Methods: A retrospective cohort study with primary data collection through structured telephone interviews was undertaken. Respondents were individuals post-stroke aged 18-74 years who had successfully passed a multi-disciplinary driver assessment. Results: Forty-five respondents were interviewed an average of 20 months following the assessment. Forty individuals were still driving. Twenty-five driving respondents reported driving in conditions that indicated confident driving. Confident driving was measured by driving frequency and distance, night driving, freeway driving and driving alone. The frequency of accidents and incidents suggests that 95% (n = 38) of drivers are 'safe'. Eight respondents reported accidents, one of which was major. In two accidents the respondent was 'at fault'. A crash rate of 222 per 100,000 drivers is within the confidence interval for similar accidents in New South Wales. Conclusions:The results of this small cohort study suggest that a multi-disciplinary driver assessment may be effective in identifying people following stroke with the ability to drive safely and confidently.

“…Five published driving studies applied Rasch analysis to develop or evaluate driving scales (Kay, Bundy, & Clemson, 2008, 2009Myers, Paradis, & Blanchard, 2008;Patomella, Kottorp, & Tham, 2008;Patomella, Tham, & Kottorp, 2006). Patomella and colleagues (2006) first applied Rasch analysis to examine the Performance Analysis of Driving Ability (P-Drive) using a driving simulator with 31 people with brain injury; they later (Patomella et al, 2008) used Rasch analysis to evaluate the P-Drive with 101 people with stroke.…”

We used the Safe Driving Behavior Measure (SDBM) to determine rater reliability and rater effects (erratic responses, severity, leniency) in three rater groups: 80 older drivers (mean age 5 73.26, standard deviation 5 5.30), 80 family members or caregivers (age range 5 20-85 yr), and two driving evaluators. Rater agreement was significant only between the evaluators and the family members or caregivers. Participants rated driving ability without erratic effects. We observed an overall rater effect only between the evaluator and family members or caregivers, with the evaluators being the more severe rater group. Training family members or caregivers to rate driving behaviors more consistently with the evaluator's ratings may enhance the SDBM's usability and provide a role for occupational therapists to interpret proxy reports as an entry point for logical and efficient driving safety interventions.
