An International Comparison of a Web-Based Personalized Feedback Intervention for Alcohol use During the Transition out of High School in the United States and Sweden.

Young adult drinkers engage in a range of drinking patterns from abstaining to heavy drinking in both the United States and Sweden. Heavy drinking during young adulthood in both countries is associated with a variety of negative consequences. Personalized feedback interventions have been identified as effective prevention strategies to prevent or reduce heavy drinking in the United States. This study examined transitions in drinking profiles and compared the efficacy of a personalized feedback intervention for 3965 young adults in the United States (1,735) and Sweden (2230) during their transition out of high school. Using goodness-of-fit criteria, results indicated that three drinking profiles exist among young adults transitioning out of high school: very low drinkers/abstainers, moderate to heavy drinkers, and very heavy drinkers. Latent Markov models revealed a moderating effect of country on personalized feedback intervention such that intervention condition participants in the United States were more likely to belong to the light drinker/abstainer or moderate to heavy profile relative to the very heavy drinking profile at 6-month follow-up. There was no significant effect of personalized feedback intervention in Sweden. Future research could investigate the impact of when personalized feedback interventions are administered and could examine if personalized feedback interventions should be more intentionally culturally adapted in order to be more effective.

Trajectories of positive alcohol expectancies and drinking: An examination of young adults in the US and Sweden.

Positive alcohol expectancies and alcohol use tend to increase from adolescence to young adulthood, yet little is known about the associations between these constructs across cultures. The current study adds to the extant literature by examining the growth trajectories of positive alcohol expectancies and drinking behavior among United States (US) and Swedish participants during a critical period where significant change in these outcomes may be expected to occur. A total of 870 (US, N=362; Sweden, N=508) high school seniors completed baseline, 6-month, and 12-month assessments of alcohol expectancies and drinking (i.e., drinks per week). Changes in positive alcohol expectancies and drinking behavior were examined using a parallel process latent growth model. In both samples, higher baseline levels of positive alcohol expectancies were associated with a higher number of drinks consumed per week at baseline. In the US sample, lower baseline levels of positive alcohol expectancies were associated with a greater increase in positive alcohol expectancies at 12-month follow-up, and lower baseline levels of drinks per week were associated with a greater increase in drinks consumed per week at 12-month follow-up. In the Swedish sample, an increase in positive alcohol expectancies over time was associated with an increase in drinks consumed per week over the same period of time. Additional research is needed to examine when and for whom expectancy-based alcohol interventions are most efficacious.

Protective behavioral strategies and future drinking behaviors: Effect of drinking intentions.

Alcohol use is common among United States and Swedish high school students and is related to negative consequences. Whereas drinking intentions are associated with future drinking behaviors, the use of protective behavioral strategies (PBS) is associated with decreased alcohol-related harm among young adults. The interactive effect of PBS and drinking intentions in predicting alcohol outcomes has not been examined. Further, because most PBS studies have been conducted among U.S. college students, PBS research among other populations is needed. The aims of this study were to evaluate longitudinally (a) the relationships between drinking intentions, PBS and alcohol outcomes, and (b) the moderating roles of drinking intentions and country in these relationships among United States and Swedish high school drinkers. Data were collected at baseline, 6- and 12-month follow-ups on 901 Swedish and 288 U.S. high school drinkers. Drinking intentions were associated with more alcohol use and consequences, and use of certain PBS was related to fewer alcohol-related consequences over time. Additionally, the negative prospective relationship between use of PBS and alcohol use, but not alcohol-related consequences, was moderated by intentions, such that the relationship was stronger among participants endorsing high drinking intentions. Country did not moderate these relationships. These results provide initial support for the generalizability of PBS college research to United States and Swedish high school students and suggest that interventions targeting the use of PBS may be most effective among high school drinkers endorsing high drinking intentions.
