Assessing the Effectiveness of Screening, Brief Intervention, and Referral to Treatment (SBIRT) With Personalized Feedback Intervention to Reduce Polysubstance Impaired Driving in Young Adults Aged 18-30 (ADAPT)

January 20, 2026 updated by: Brittney Hultgren, University of Washington
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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Waitlist control
Individuals will have received SBIRT but will be on a waitlist to receive the brief personalized intervention for 3 months after baseline assessment.
Behavioral: Personalize Feedback Intervention
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.
Experimental: Active Intervention
Participants will have received SBIRT and receive the brief online personalized intervention immediately after baseline assessment.
Behavioral: Personalize Feedback Intervention
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.

Question asks: How long do you typically wait to drive after using alcohol and Cannabis used at the same time so that the effects overlap. Participants answer in hours and minutes which is transformed into total number of minutes.
