What is it about?
Alcohol expectancies are a critical factor in the development of problematic alcohol use. Expectancy challenge (EC) interventions aim to manipulate positive alcohol expectancies to reduce or prevent alcohol use among young people. In this meta-analysis, we investigated the effects of ECs at changing expectations and alcohol use among high school and college students, and moderating effects of study and individual characteristics on these changes.

Why is it important?
This meta-analysis suggests that EC interventions modestly reduce alcohol use among college and high school students, and that ECs that target college students and that are delivered at a higher dose can produce more favorable effects.
