Underage drinking is a serious national problem--alcohol-related injuries are a leading cause of death and injury among young people in the United States today. This guide is designed to help individuals who wish to be involved in a national effort to prevent underage drinking. It includes materials and messages that can be reproduced, as well as other information that can be tailored for a specific community or audience. The guide will help in creating a broad-based public education program to communicate to neighbors the seriousness of the teen drinking problem and to motivate community members to become a part of the solution. Some of the topics addressed here include ways to create a teen drinking prevention program in one's community, including sample letters to elected officials and establishments that sell alcohol. Also detailed are the role of the spokesperson and strategies for gaining access to the news media, such as effective ways to communicate with reporters and editors, techniques for targeting messages and audiences, some sample press releases, some sample opinion editorials, and examples of public service announcements for radio.
