A Group Randomized Trial of the Stop Service to Obviously-Impaired Patrons (S-STOP) Program to Prevent Overservice in Bars and Restaurants in College Communities.

Background: College student drinking in on-premises establishments has been associated with heavy alcohol consumption and a range of problems including assault, fighting, risky sex, and drinking and driving. Although more strictly enforcing overservice laws might reduce heavy drinking in on-premises establishments, law enforcement agencies have few resource-efficient tools for doing so, resulting in these laws seldom being enforced.

Objectives: In this paper, we report the results of an evaluation of the Stop Service to Obviously-impaired Patrons (S-STOP) program that was implemented in 303 bars and restaurants in 18 university communities in California using a randomized cross-over design (early vs.

Effects of a responsible retailing mystery shop intervention on age verification by servers and clerks in alcohol outlets: A cluster randomised cross-over trial.

Introduction And Aims: Clerks and servers at alcohol establishments often fail to verify age. Using mystery shoppers to provide performance feedback is one approach to improving age verification. Few controlled studies have evaluated mystery shop interventions.

Mystery shops involving attempted tobacco purchases by young buyers have been implemented in order to monitor retail stores' performance in refusing underage sales. Anecdotal evidence suggests that mystery shop visits with immediate feedback to store personnel can improve age verification. This study investigated the effect of monthly and twice-monthly mystery shop reports on age verification.
