Evaluating Perceived Fitness to Drive While Intoxicated
Study Details
Study Description
Brief Summary
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Participants Blinded to BrAC reading (Control) Participants randomized to this arm will consume three weight-based doses of alcohol with a target BAC of 0.10 and comple breathalyzer measurements every 20 minutes until a BAC of 0.03 is reached. They will complete a visual analog scale (the Self-Reported intoxication Survey) on their perceived fitness to drive and be blinded to their breath alcohol readings with the BACtrack Mobile Pro device. |

| Experimental: Participants Aware of their BrAC reading Participants randomized to this arm will consume three weight-based doses of alcohol with a target BAC of 0.10 and comple breathalyzer measurements every 20 minutes until a BAC of 0.03 is reached. They will be shown their breath alcohol readings with the BACtrack Mobile Pro device before completing a visual analog scale (the Self-Reported intoxication Survey) on their perceived fitness to drive. |
Behavioral: Participants Shown their Breath Alcohol Content Measurement
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.

Outcome Measures
Primary Outcome Measures
- Participants' Perceived Fitness to Drive Measurement [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 each Breath Alcohol Content Measurement collected
Secondary Outcome Measures
- Participants' Perceived Willingness to Drive Measurement [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 each Breath Alcohol Content Measurement collected
