Psychometric prediction of driving performance among the disabled.

A battery of psychometric and performance tests was administered to 25 subjects who were classified into able-bodied (n = 8), brain-injured (n = 10), and spinal cord injured groups (n = 7). All disabled subjects were regarded by their referring rehabilitation therapists as potential candidates for driver assessment. Data were analyzed to identify which measures were useful in differentiating among the groups and predicting driving performance. Results indicated that psychometric measures can be useful in predicting driving performance among disabled drivers. Nearly all the measures in the battery were significant predictors of driving ability, and some were highly predictive. The best was the oral version of the Symbol Digit Modalities test, which by itself accounted for 70% of the variance of the full-sized-vehicle driving score. Adding a second variable into a two-step multiple regression further increased the correlation between predictors and driving, accounting for almost 80% of the variance in driving score. These findings support the feasibility of developing a simple test battery to determine which disabled candidates are ready for in-vehicle assessment, and which candidates are not ready without further evaluation of cognitive and performance skills.

A small-scale vehicle for assessing and training driving skills among the disabled.

A small-scale vehicle (SSV) was developed to assess and train skills of disabled individuals who wish to become licensed to drive. The SSV incorporates power-assisted adjustable-effort steering and braking functions, variable-speed control, modular interchangeable hand control units, standard foot-control units, and a variety of safety and instrumentation features. This vehicle offers numerous advantages over traditional modes of assessment and training. These advantages include its lower price and operating costs as compared to a full-sized vehicle; its adaptability to left- or righthanded clients; and the provision of a specially adapted vehicle for vehicle for practice driving and regaining skills and self-confidence away from public thoroughfares. The SSV is one component in the Center's driving assessment and education curriculum that follows a graded progression, beginning with use of a driving simulator, to driving the SSV, to driving a full-sized vehicle.

Curriculum evaluation: a crucial component of dietetic programs.

The Nominal Group Technique was used to evaluate the existing CUP curriculum at Louisiana Tech University. Forty-five persons involved in the program participated in one of three workshops. The nominal group process successfully generated ranked and weighed "problem" statements to be addressed in program revision. The NGT allowed input from all individuals, leading to the clinical practitioners "owning" the crucial clinical experience component of the coordinated undergraduate program.
