Study summary

Responsible beverage service (RBS) training for alcohol servers is a promising intervention for reducing driving while intoxicated (DWI) by alcohol. Training, certification, and in-service contact improves professionalism and effectiveness of prevention interventions delivered by community members such as alcohol servers. This SBIR Fast-track project will develop and test an in-service professional development component to the WayToServe® online RBS training to improve the effectiveness of RBS training in order to make further gains in reducing problem alcohol behavior in communities.

Read the detailed description

Among the interventions targeting driving while intoxicated (DWI) by alcohol, Responsible Beverage Service (RBS) training of alcohol servers has shown promise. RBS training is currently required or incentivized by 36 U.S. states and California will require it starting in 2022. The research team has shown that an online RBS training, named WayToServe®, was effective in two randomized trials. These results filled a gap in the literature on RBS training that is limited by the lack of randomized trials, poor measurement of training implementation, and almost exclusive focus on live training when online training predominates. The goal of this SBIR Fast-track research is to develop and test an in-service professional development component for alcohol servers trained by WayToServe to improve its effectiveness. It is intended to motivate servers to implement the RBS skills in the face of common barriers, provide support for RBS actions from a "community" of alcohol servers, and prevent natural degradation of skills over time. Rationale for this product is provided by past research showing that training, certification, and in-service contact improves professionalism and efficacy of community prevention interventions. Scientific premise is provided by the positive results of our trials on the WayToServe® training. The in-service component will be delivered through the WayToServe Facebook page that currently is "followed" by over 20,000 alcohol servers trained by WayToServe. The specific aims of Phase I are to: 1) develop content of in-service professional development on RBS skills with a) premises owners/ managers interviews and b) alcohol servers in New Mexico and Washington State trained by the WayToServe online RBS training through focus group discussions; 2) produce a prototype WayToServe Plus in-service professional development component in flowcharts and an initial library of Facebook posts, including text, graphics, and interactive elements and evaluate it for acceptability, usability, and engagement in focus groups and field pilot trial with alcohol servers in New Mexico and Washington State trained by the WayToServe online RBS training, and 3) determine feasibility of WayToServe Plus in-service professional development component and develop evaluation plans for Phase II research. Milestones will be an EAB-approved Phase I research plans and development of the content outline and WayToServe Plus prototype, evaluation of WayToServe Plus prototype, and feasibility assessment of the WayToServe Plus in-service professional development component. Phase II specific aims will achieve the milestones of full production of WayToServe Plus and a randomized trial testing its effectiveness by: 4) producing the full WayToServe Plus in-service professional development component and 5) conducting a randomized trial with 160 alcohol premises in New Mexico and Washington State evaluating effectiveness of WayToServe Plus on refusal of sales to PiP (primary outcome). The SBIR research is innovative as WayToServe Plus will be the first continuous in-service professional development for RBS and will increase the WayToServe training's effectiveness and commercial advantage with alcohol servers and corporate clients.

Interventions

  • BehavioralWayToServe Plus In-service Component

    Investigators will test WayToServe Plus in-service component's ability to increase refusal of service to intoxicated patrons in a randomized trial. A two-group randomized field trial (WayToServe training only \[comparison control\] v. WayToServe training plus WayToServe Plus in-service component \[intervention\]) with 2 assessment rounds (Baseline, Posttest) will yield a 2 factorial design. Investigators will randomly assign premises to WayToServe training and WayToServe Plus after baseline in Month 18, stratified by state and location. Remaining premises will receive WayToServe Training Only. All premises will be recruited to have servers complete WayToServe training. Servers in intervention group will be accepted into a Facebook private group after WayToServe training to receive in-service component with \~3 posts per week for 12 months. In Months 30-32, all premises will be posttested with PiP assessments (blind to condition).

What researchers measure

Primary outcomes

  1. Refusal rate of alcohol service to apparently-intoxicated patrons

    Primary outcome measure, refusal rate of alcohol service to apparently-intoxicated patrons, will be obtained via a pseudo-intoxicated patron (PiP) assessment. Confederate buyers will feign intoxication and record if servers agree to serve them an alcoholic beverage. PiP protocol presents a server with the most overt situation in which alcohol service should be refused, (i.e., when a patron is showing clear signs of intoxication), models behavior of patrons most at risk, and is relatively low cost.

    Time frame: Change in refusal rate between baseline and 1 year posttest assessments

Ran from Oct 2022 to primary completion in May 2026, 43 months.

Of 336 interventional studies with no phase under Alcohol Drinking, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 45. This study's 43 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
