Brief 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.

Outcome Measures

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.

    Change in refusal rate between baseline and 1 year posttest assessments

Study Arms (2)

WayToServe Plus In-service Component

EXPERIMENTAL

Intervention group of servers to participate in Facebook group.

Behavioral: WayToServe Plus In-service Component

WayToServe Training Only

EXPERIMENTAL

Control group of servers who do not participate in Facebook group and receive WayToServe Training only.

Behavioral: WayToServe Training Only

Interventions

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).

WayToServe 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 Plus In-service Component \[intervention\]) with 2 assessment rounds (Baseline, Posttest) will yield a 2 factorial design. Investigators will randomly assign premises to WayToServe Traiing Only after baseline in Month 18, stratified by state and location. In Months 30-32, all premises will be posttested with PiP assessments (blind to condition).
