Trial Outcomes & Findings for Impaired Risk Awareness During Intoxication in DUI Offenders (NCT NCT05247788)
NCT ID: NCT05247788
Last Updated: 2026-05-12
Results Overview
Alcohol consumption will be assessed at monthly intervals from baseline to follow up and will be measured using a timeline follow back assessment. Participants will self-report data on number of days when the participant demonstrates binge drinking (5+ drinks per day for men; 4+ drinks per day for women).

Participant Flow
Orientation session all subjects complete binge drinking measure (TLFB) and PACS. Up to 1 week later, participants attend a Pre-Intervention session, all receive 0.65 g/kg dose of alcohol or placebo on separate days in a counterbalanced order. Subjects are then randomized to intervention or no intervention.

Baseline characteristics by cohort
| Measure |
Intervention Group
n=55 Participants
Participants will complete an intervention session in which they receive a controlled alcohol dose with structured feedback and training to accurately appraise the impairing effects of alcohol and estimate their blood alcohol concentration (BAC).
Blood alcohol concentration (BAC) discrimination training: Subjects will receive 0.65 g/kg alcohol to yield a peak BAC of 85 mg/dl (0.085%). They will be trained to accurately estimate their BAC using the Body Scan Exercise with BAC feedback.
Performance feedback training: This training element targets the driver's self-efficacy by increasing their awareness of the behavioral impairing effects of alcohol that are experienced at BACs at and even below the legal limit (50-80 mg/dl).
|
No Intervention Group
n=57 Participants
Participants assigned to the no intervention group undergo the same alcohol dose exposures over the session but receive a general body scan and do not receive feedback concerning BAC or performance.
Blood alcohol concentration (BAC) discrimination training for controls: Subjects will receive 0.65 g/kg alcohol to yield a peak BAC of 85 mg/dl (0.085%). They will be given a general Body Scan Exercise with no feedback.

Timeframe: BaselineChange in tonic alcohol cravings over the past week will be assessed using the Penn Alcohol Craving Scale (PACS) which is a five-item self-report indicated with strong psychometrics. 'Frequency' is the frequency of craving with a score on a Likert scale ranging from 0 to 6 with higher scores meaning worse craving. 'Strong' is the intensity of craving with a score on a Likert scale ranging from 0 to 6 with higher scores meaning worse craving. 'Time' is the duration of craving with a score on a Likert scale ranging from 0 to 6 with higher scores meaning worse craving. 'Resist' is the inability to resist craving with a score on a Likert scale ranging from 0 to 6 with higher scores meaning worse craving. 'Crave' is overall craving with a score on a Likert scale ranging from 0 to 6 with higher scores meaning worse craving. PACS uses a 0-6 point Likert scale for each item where a higher number for each of the five items indicates more cravings. Total scores range from 0 to 30.

Timeframe: Baseline (Intervention Session)The Multidimensional Assessment of Interoceptive Awareness Ver. 2 (MAIA-2) is a 37-item self-report measure of 8 dimensions of self-perceived interoceptive ability. The dimensions are: Notice (awareness of uncomfortable, comfortable, or neutral body sensations), Not Distracted (tendency not to ignore or distract oneself from sensations of pain or discomfort), Not Worried (tendency not to worry or experience emotional distress with sensations of pain or discomfort), Attention Regulation (ability to sustain and control attention to body sensations), Emotion (awareness of the connection between body sensations and emotional states), Self-Regulation (ability to regulate distress by attention to body sensations), Body (tendency to actively "listen" to the body for insight), and Trust (experience of one's body as safe and trustworthy). The minimum score for each of the eight dimensions is 0 while the maximum score is 5, with higher scores indicating better outcomes/greater interoception.
