Alcohol: True Stories Hosted by Matt Damon is a multimedia intervention designed to prevent or reduce alcohol use among young people in grades 5-12 by positively changing the attitudes of youth and their parents and other caregivers in regard to youth drinking. The intervention features a 20-minute video, hosted by Matt Damon, which tells the stories of four adolescents’ experiences with alcohol; story topics include drinking and driving, lost opportunities, addiction, alcohol-related violence, and the effects of alcohol use on relationships. Through the four stories, the video addresses reasons that motivate young people to drink: to fit in, to ease social interaction, to relieve stress, to have fun, and because they are addicted. The young people profiled describe the consequences of underage drinking and the benefits of waiting to drink alcohol until after reaching legal age, and they offer healthy coping strategies for stressful life events as well as methods to avoid drinking alcohol. The video is accompanied by a discussion guide, which is designed to provoke candid conversation regarding alcohol use and to help young people internalize anti-underage drinking messages and think critically about their own decisionmaking regarding alcohol use.
