An Experimental Test of Reward & Reminder as a Stand-Alone Program to Prevent Alcohol Sales to Underage Youths

Compliance Checks Decrease Cigarette Sales Rates to Pseudo-Underaged Mystery Shoppers: A Quasi-Experimental Control Group Study

To control adherence to age limits regarding sales of tobacco products, Swedish authorities can conduct compliance checks. Compliance checks involve prior information to all retailers, mystery shopping, and subsequent feedback to the retailers. This study investigated whether compliance checks can decrease the rates of cigarette sales to underaged adolescents. Test purchases of cigarettes were conducted using pseudo-underaged mystery shoppers, i.e., 18-year-old adolescents with a younger appearance not carrying ID, to measure the refusal rate and rate of ID checks. Test purchases were conducted at 257 retail outlets in 13 municipalities in Stockholm County at baseline 2017 and follow-up 2019, respectively. In between the measurements, six municipalities (intervention area) conducted compliance checks, and seven municipalities were used as a comparison. Comparing baseline and follow-up, rates of refusal (70.4 to 95.8%) and ID checks (80.3 to 95.8%) improved in the intervention area. In the comparison area, refusal rates increased (80.9 to 85.2%), and ID check rates remained stable (at 86.1%). Significant group × time interaction effects reveal that the rates of refusal and ID checks differently changed in the study areas over time. These results indicate that compliance checks are an effective method to decrease cigarette sales to underaged adolescents.

A Component Evaluation of a Randomised Control Community Intervention to Reduce Adolescent Alcohol Use in Australia

Despite a decline in Australian adolescents reporting to have consumed alcohol, a high proportion of the adolescent population still consumes alcohol. Community-led prevention interventions that systematically and strategically implement evidence-based programs have been shown to be effective in producing population-behaviour change related to youth alcohol and drug use. This study evaluated the post-intervention effects of a multi-component community intervention in Australia. It comprised social marketing targeting adolescents and parents, and a community intervention to reduce underage alcohol sales. Structural equation modelling was used to examine direct and indirect effects of community intervention components on intention and consumption. Self-report surveys (N = 3377) and community sales data (27 communities) were analysed to evaluate the effect of the intervention components on intention and consumption before the age of 18. The intervention reduced alcohol sales to minors (OR = .82). Exposure to the social marketing was significantly associated with household no-alcohol rules (OR = 2.24) and parents not supplying alcohol (OR = .72). The intervention predicted intention not to consume alcohol before age 18; intention was associated with not consuming alcohol (OR = 5.70). Total indirect effects from the intervention through to intention were significant. However, parents setting a rule and not supplying alcohol were the only significant direct effects to intention. Parents setting a rule was directly associated with lower consumption. Overall, the intervention logic was supported by the data modelling. The study extends prior knowledge of community-based interventions to prevent adolescent alcohol use by identifying critical intervention components and effect mechanisms.

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. delayed implementation). The S-STOP program: (a) deployed pseudo-intoxicated patrons who attempted to purchase a drink when showing obvious signs of intoxication; (b) provided feedback to owners and managers on staff performance; and (c) offered free online refresher training for staff.

RESULTS

Overall, alcohol servers in bars and restaurants in these college communities were willing to serve a pseudo-intoxicated mystery shopper 90% of the time. The study found no evidence that S-STOP reduced the prevalence of alcohol sales to apparently impaired patrons during the two intervention stages of the study.

CONCLUSIONS

The findings highlight the need for developing effective interventions to prevent overservice and should prompt college and university leaders to take the lead in addressing the problem of alcohol overservice at on-premises establishments by working with community leaders, law enforcement, and retailers.

Evaluation of a Mystery Shopper Intervention to Reduce Sales of Alcohol to Minors in Zacatecas and Guadalupe, Mexico

We report the results of a quasi-experimental evaluation of a mystery shopper intervention in Zacatecas and Guadalupe, Mexico. Underage youth attempted to purchase beer at 50 Modelorama stores and 32 Oxxo stores (intervention groups), and at 19 comparison convenience stores in March, July, and August 2018. After each attempt, intervention store operators were informed if a sale was made. Modelorama operators also received training and were warned that repeated sales to minors could jeopardize their franchise. Average sales rates to minors were 63.8% at Modeloramas, 86.5% at Oxxo stores, and 98.2% at comparison stores. The findings suggest that mystery shopper interventions with training, feedback to store operators, and sanctions after repeated sales to underage youth may reduce sales to minors in low- and middle-income countries.
