NCT02765672

Brief Summary

The main objective of this study is to discern if an Occupational Therapy Driving Intervention (OT-DI) improves fitness to drive abilities of Combat Veterans and also investigate if results leads to reduced driving errors on the driving simulator and an on-road test. The driving behavior of 260 Combat Veterans will be studied on a driving simulator at baseline after which they will be randomized into control and intervention groups. The intervention group will receive sessions of Occupational Therapy Driving Intervention by a trained driving rehabilitation specialist. The control group on the other hand will receive driving safety education sessions by a driving safety professional. Both groups will be evaluated for driving performance on the driving simulator to ascertain whether there have been changes in the number of driving errors at two and three months upon enrollment. Caregiver responses on driving behavior of Combat Veteran and public driving records from The Department of Motor Vehicles will be analyzed to for changes in number of driving errors.

Outcome Measures

Primary Outcomes (1)

  • Simulator driving errors changes within the experimental and control groups at baseline, months 2 and 5

    Simulator driving errors will be quantified at baseline and at month 2 and 5 for the experimental and control groups.

    Changes in baseline at months 2 and 5

Secondary Outcomes (1)

  • On-road driving errors changes within the experimental and control groups at baseline and month 5

    Changes in baseline at months 5

Study Arms (6)

Control Group

ACTIVE COMPARATOR

Participants in this group will have the following performed: Institute of Mobility Activity and Participation's clinical battery tests and a simulated driving evaluation, a Brief Driving Behavior Interview, Propensity for Angry Driving Scale, Clinical Driving Assessment, Community Integration Questionnaire, Fitness-to-Drive Screening Measure (FTDS), and a Satisfaction with Life Questionnaire. Driving Safety Education by a traffic safety professional, three x 1 hour sessions to discuss traffic safety rules regarding person, vehicle, environmental factors.

EXPERIMENTAL

Participants in this group will have the following performed: Institute of Mobility Activity and Participation's clinical battery tests and a simulated driving tests, a Brief Driving Behavior Interview, Propensity for Angry Driving Scale, Clinical Driving Assessment, Community Integration Questionnaire, Fitness-to-Drive Screening Measure(FTDS), and a Satisfaction with Life Questionnaire. Occupational Therapy Driving Intervention (OT-DI) consisting of three x 1 hour sessions to review explicit driving errors, strategies to mitigate errors and receiving feedback from the evaluator after driving the simulator.

Caregiver Control Group

ACTIVE COMPARATOR

Caregiver control group will fill out a Fitness-to-Drive Screening Measure (FTDS) questionnaire at baseline and at the end of the study.

Caregiver Experimental Group

ACTIVE COMPARATOR

Caregivers of the experimental group will fill out a Fitness-to-Drive Screening Measure (FTDS) questionnaire at baseline and at the end of the study.

Behavioral: Fitness-to-Drive Screening Measure (FTDS)

On-road driving Group

ACTIVE COMPARATOR

A subset of 30 Combat Veterans will be drawn from the control group (15 no.) and experimental group (15 no.). This group of Combat Veterans will will undergo an on-road driving test at baseline and month 5

Procedure: On-road driving test

Simulator-drives Evaluation Group

ACTIVE COMPARATOR

This group will comprise of 30 Combat Veterans who will be drawn outside of the randomized experimental and and control groups participants. This group will only perform simulator driving triggers evaluation

Procedure: Driving triggers evaluation

Interventions

This will be completed thrice, at baseline, post-test1 and at post-test2 (3 months after post test 1)

Control GroupExperimental Group

Clinical Driving Assessment includes Optec vision screening, Useful Field of View, Range of Motion, Mini-Mental State Examination (MMSE) and Strength tests. This will be completed thrice, at baseline, post-test1 and at post-test2 (3 months after post test 1)

Caregiver Control GroupCaregiver Experimental GroupControl GroupExperimental Group

This involves driving a simulator fitted simulated drives engineered to to address Veteran's driving concerns such as reactions to other drivers and road conditions(e.g. debris). The simulator is used at baseline and at post-test1 and 2. The intervention and traffic safety education session 3 also occurs using the driving simulator.

Control GroupExperimental Group

This involves the following: Session1: general traffic safety discussion; Session 2: Rules of the road and acknowledgement of the road discussion and Session 3: driving the simulator without any feedback from traffic safety professional

Control Group

This has three sessions: 1. Driving evaluator reviews explicit driving errors with Combat Veteran; 2. driving evaluator provide tailored strategies to mitigate errors; Combat Veteran drives simulator with targeted feedback from driving evaluator.

Experimental Group

This involves and on-road driving test supervised by Driving Rehabilitation Specialist. To be completed at baseline and at month 5

On-road driving Group

The simulator-drives evaluation group will evaluate the current simulator-triggers prior to baseline testing
