Although the facts about underage drinking are widely known, the issues that surround this problem vary from one community to the next. Such issues include where and how underage drinking shows itself, how it is viewed by the community, and what residents think is a reasonable way to address underage drinking in their community. This guide is designed to help community members gather accurate information that will reflect the parameters of the teen drinking problem in their community. The guide offers help on defining program goals, how to include important sectors of fellow residents in planning and activities, and how to acquire needed support. This kind of risk assessment will allow a community to determine what programs, methods, or activities may best meet the needs of the community, rather than relying on actions advanced by a few vocal groups. Information is given on how to create a community risk assessment opinionnaire, such as selecting the target population, sampling, and getting a good response. Likewise, the guide explains how to perform a community audit, providing details on how to collect data, process the information, and prepare a report. A model opinionnaire and audit are appended.
