Identifying scale and person response validity of a new assessment of driving ability

The purpose of this study was to examine the extent to which occupational therapists (OTs) are involved in driving assessments in Sweden and how these assessments are performed. A questionnaire was sent to 154 geriatric, rehabilitation, and neurological clinics, and additionally directly to 19 OTs who had purchased a test battery specifically used for driving assessments. The response rate was 60%. Of those responding, 57% reported being involved in fitness-to-drive assessments. However, such assessments were carried out in various manners and diverse methods were used, ranging from unstandardized activity assessments to a test developed specifically for driving assessments. Only 19% used on-road driving tests as a complement to the clinical assessments. Apart from the lack of appropriate methods, the respondents said that they did not have sufficient knowledge to perform driving assessments and expressed a need for further education. In the future it seems necessary for OTs in Sweden to undergo specialized training and perform the assessments on a regular basis to maintain a high level of competence as driving assessors.

“…In the present study infit and outfit statistics were concurrently analysed in order to get as much information as possible about the psychometric properties of the META. Acceptable goodness-of-fit was indicated by an infit and outfit MnSq ≤ 1.4 (33) associated with z < 2 (22), a criteria used earlier in development of assessments of clinical observations (34,35).…”

Title: Psychometric evaluation of a new assessment of the ability to manage technology in everyday life. AbstractTechnology increasingly influences the everyday lives of most people, and the ability to manage technology can be seen as a prerequisite for participation in everyday occupations.However, knowledge about ability and skills required for management of technology is sparse. This study aimed to validate a new observation-based assessment, the Management of Everyday Technology Assessment (META). The META is developed to assess the ability to manage technology in everyday life. A sample of 116 older adults with and without cognitive impairment were observed and interviewed by the use of the META when managing their everyday technology at home. The results indicate that the META demonstrates acceptable person response validity and technology goodness-of-fit. Additionally, the META can separate individuals with higher ability from individuals with lower ability to manage everyday technology. The META can be seen as a complement to existing ADL assessment techniques and is planned to be used both in research and practice.

“…P-Drive was used to score the participants' driving performance (what the driver did), observed during the test in the simulator. P-Drive has demonstrated evidence of internal scale and person response validity (13,28). In P-Drive, 20 items (for a complete overview of the items/actions covered in P-Drive, see (28)) are scored using a criterion-referenced rating, based on the quality of performance on a scale from 4 to 1, where 4 0competent driving action, 30questionable driving action, 2 0problematic driving action, and 1 0incompetent driving action.…”

“…An assessment tool to measure driving ability in a driving simulator, P-Drive (Performance Analysis of Driving Ability), has recently been developed. P-Drive measures what the driver actually does during a driving evaluation in a realistic setting and measures actions taken during driving at the operational and tactical levels of decision-making according to Michon's (12) hierarchical model of driving (13,14). At the operational level the driver makes decisions about the basic manoeuvring of the car, such as steering and braking; at the tactical level the driver makes decisions to better master and adapt to different traffic situations like adjusting speed and planning ahead.…”

Awareness of driving disability in people with stroke tested in a simulator

The aim of this study was to explore and describe awareness of driving disability in people with driving difficulties after stroke. The study comprised a consecutive sample of 38 participants with stroke who showed difficulties in a technically advanced, interactive driving simulator. Driving ability in the simulator was measured using Performance Analysis of Driving Ability (P-Drive). Awareness of driving disability was measured using a modified version of Assessment of Awareness of Disability (AAD), measuring the discrepancy between observed driving actions and self-reported disability after a driving evaluation in a simulator. A majority of the participants (n = 36) demonstrated driving ability that was below the cut-off criterion for P-Drive. Furthermore, a majority of the items measuring awareness of driving disability were scored low, indicating that participants with stroke who did not pass a driving evaluation also had limited awareness of driving disability. A General Linear Model analysis indicated that awareness of driving disability and cognitive screening outcome explained 74% of the variance in driving ability. This study indicated that a majority of the people with stroke who fail a driving evaluation also have limited awareness of their disability, which indicates the need to address awareness in driving evaluations.
