Project OPTIONS is a four-year NIAAA-funded research project designed to evaluate the efficacy of a brief intervention for preventing alcohol use problems among adolescents enrolled in Miami-Dade county public high schools. The overall aim of the project is to develop, standardize, and disseminate a low cost, developmentally appropriate, culturally sensitive prevention program for facilitating adolescent efforts for early resolution of their alcohol problems. The program was initially developed by a team of researchers from UC San Diego led by Dr. Sandra Brown, who found the program to be effective for preventing alcohol problems among high school students enrolled in the San Diego public school system. The current study represents an extension of this work to multiple sites to replicate intervention findings and assess generalizability of the standardized intervention protocol. During the course of the project, approximately 480 participants will be randomly assigned to one of two conditions: Motivational Interviewing (MI) or Education only (ED). The program consists of 6 group-format sessions designed to enhance deliberative decision making in alcohol use situations by promoting discussions related to perceptions of use, use/nonuse expectancies, and management of peer-related alcohol use situations. Participants are assessed immediately before intervention and at 4- and 12-week follow-up contacts.
