The Employee Stress and Alcohol Project (ESAP) developed an interactive computer-based alcohol abuse prevention and early intervention program accessible to employees over the Internet. Behavioral health research recommends that specialists develop and provide comprehensive yet cost-effective approaches to alcohol abuse prevention, early intervention, and treatment within the context of workplace managed care. ESAP is implementing this web site for a diverse 8,567-employee work site. ESAP's web site enables employees to self-assess their stress levels, coping styles, and risk for alcohol-related problems. It provides personalized feedback, recommendations, mini-workshops, a drinking journal, links to other online resources, and an interactive forum for direct participant-to-participant communication. ESAP's web site provides resources for employees who are concerned about another individual's drinking as well as information about adolescent alcohol use. This article discusses the implications of incorporating the ESAP web site into worksite alcohol abuse prevention and early intervention programming.
