Impaired Driving
Conditions
Brief summary
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.
Interventions
BEHAVIORALPersonalize 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.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of times in the past 3 months participants drove impaired by both alcohol and cannabis at 3 month follow-up | From baseline to 3 months later at 3 month follow up assessment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of times in the past 3 months participants drove impaired by both alcohol and cannabis at 6 month follow-up | 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 cannabis only at 3 month follow-up | From baseline to 3 months later at 3 month follow-up assessment | — |

| Number of times in the past 3 months participants drove impaired by cannabis only at 6 month follow-up | From 3 months after baseline to 3 months later at 6 month follow-up assessment | — |
| Reported wait time to drive after using both alcohol and cannabis measured in minutes at 3 month follow up | From baseline to 3 months later at 3 month follow up assessment. | 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. |
