Evaluating Perceived Fitness to Drive While Intoxicated

The goal of this study is to conduct a laboratory-based pilot randomized control trial of smartphone-enabled breath alcohol monitoring on perceived fitness to drive a vehicle among intoxicated adults. The study team will enroll up to 30 adults aged > 21-44 who are frequent drinkers without dependence who drive more than four times per week to complete a standardized alcohol drinking protocol in a monitored setting collecting breathalyzer measurements. The protocol involves consuming three weight-based doses of alcohol with a target BAC of 0.10 and completing breathalyzer measurements every 20 minutes until a BAC of 0.03 is reached. The control group will complete a visual analog scale on their perceived fitness to drive and be blinded to their breath alcohol readings with the BACtrack Mobile Pro breathalyzer device, while the intervention group would do the same, but be shown their breath alcohol readings on the paired BACtrack smartphone application. The research team's previous research has validated the accuracy of the BACtrack Mobile Pro device to measure BAC within +/- 0.001 of police-grade breathalyzer and estimate BAC within +/- 0.01 of a blood test.

Treatment and study plan

Participants Shown their Breath Alcohol Content Measurement

Behavioral

Each time a Breath Alcohol Content (BrAC) Measurement is taken by the research team, the participant is shown the measurement before completing the paper visual analog scale scale (the Self-Reported intoxication Survey) on their perceived fitness to drive.

Primary outcomes

  1. Participants' Perceived Fitness to Drive Measurement

    Time frame: The duration of study visit, up to 8 hours

    Participant's self rating on visual analog scale from 1-10 (1: Extremely Able to Drive; 10: Not at all Able to Drive) after Breath Alcohol Content Measurement was collected

Secondary outcomes

  1. Participants' Perceived Willingness to Drive Measurement

    Time frame: The duration of study visit, up to 8 hours

    Participant's self rating on visual analog scale from 1-10 (1: Not at all Willing to Drive; 10: Extremely Willing to Drive) after Breath Alcohol Content Measurement was collected
