Driving Performance as Assessed by Standard Deviation of Lateral Position (SDLP)
Lasso di tempo: Baseline, 1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, and 7.5 hours
|
The STISIM Drive® M4000-R Console system will be used to assess driving performance, a state-of-the-art technology that has been independently validated to reflect real-world driving conditions.
SDLP (measured in cm) was calculated across all drives to get a composite index of lateral control and reported as peak change from baseline.
SDLP is the gold standard of quantifying the magnitude of driving impairment from drugs and alcohol and has excellent predictive validity to actual driving.
Scores range from 0 to no upper limit.
Higher scores represent higher magnitude of driving impairment.

Lasso di tempo: Baseline, 1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, and 7.5 hours
|
Driving impairment will be assessed via a composite drive score.
The composite drive score is derived by integrating various driving outcomes (see primary and secondary driving outcomes).
Higher z-score indicates worse performance.
The score is on a z-score scale, meaning a score of 1 equates to 1 standard deviation outside of the participants' mean baseline performance and a Z-score of 0 represents the mean baseline performance.
This was calculated across all drives and reported as peak change from baseline.
