About this study
The current study is assessing the effects of receiving Screening, Brief Intervention and Referral to Treatment alone versus also receiving a brief online personalized intervention on impaired driving behaviors among Washington State young adults aged 18-30.
Read the detailed description
The current project is inviting young adult aged 18-30 in Washington State who screen at moderate or moderate to high risk or who report impaired driving during Screening, Brief Intervention and Referral to Treatment. Consented young adults would be randomized to receive a brief online personalized intervention or waitlist control and be assessed at enrollment and 3 months later. A selection of participants will be assessed at 6 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Personalize Feedback InterventionBehavioural
The brief online personalized feedback intervention (PFI) is adapted from the personalized feedback provided in BASICS, iCHAMP, studies using similar standalone PFI approaches. Specifically, feedback adapted from these brief motivational interventions and prior projects include: Patterns of use: alcohol, cannabis, other drug, and polysubstance use frequency, alcohol and cannabis quantity and peak; Substance use norms; Expectancies of use of alcohol ; Estimates on money the participant spends on alcohol and cannabis compared; Protective behavioral strategies; Alcohol- and/or cannabis-impaired driving norms; Wait time to drive and related psychoeducation; Additional psychoeducation is provided (e.g., standard drink; information on tetrahydrocannabinol (THC) percentages) throughout the feedback to improve understanding and motivation for change.
| Study group | Role | What they receive |
|---|---|---|
| Waitlist control | Active comparator | Individuals will have received SBIRT but will be on a waitlist to receive the brief personalized intervention for 3 months after baseline assessment. Receives: Behavioral: Personalize Feedback Intervention |
| Active Intervention | Experimental | Participants will have received SBIRT and receive the brief online personalized intervention immediately after baseline assessment. Receives: Behavioral: Personalize Feedback Intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of times in the past 3 months participants drove impaired by both alcohol and cannabis at 3 month follow-up
Measured: From baseline to 3 months later at 3 month follow up assessment.
Secondary outcomes (11)
Number of times in the past 3 months participants drove impaired by both alcohol and cannabis at 6 month follow-up
Measured: From 3 month after completing baseline to 3 months later at the 6 month follow-up assessment
Number of times in the past 3 months participants drove impaired by alcohol only at 3 month follow-up

Questions about this trial
What is this clinical trial studying?
A study testing Personalize Feedback Intervention in people with Impaired Driving, run by University of Washington.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 27 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Brittney Hultgren, PhD (206-221-4657, hultgren@uw.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of times in the past 3 months participants drove impaired by both alcohol and cannabis at 3 month follow-up (time frame: From baseline to 3 months later at 3 month follow up assessment.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2026; AzTrials last refreshed its copy on 7 Nov 2026.
