What is the Environmental Survey Instrument. The ESI is a phone survey created to evaluate the perceptions of community members around how coalitions are implementing environmental strategies to prevent underage drinking as well as binge drinking among young adults. The study acknowledged the problems found in trying to evaluate environmental strategy efforts of community coalitions.
The survey included over 1,800 respondents across seven large counties in Texas. They found connections between intervening variables, also called community factors, and alcohol-related behaviors. For example, people who perceive easy community access to alcohol were more likely to report driving while intoxicated.
