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.
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.

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.
