All students referred to ADAPS completed a baseline assessment questionnaire. Using data from the initial assessment, eligibility was determined and an individualized profile was created for each eligible student. The personal profile included information on peer norms for alcohol and drug use, typical peak BAC, alcohol- and drug-related problems, alcohol expectancies, high-risk behaviors (e.g., driving under the influence, unplanned sex after using alcohol or drugs), and personal risk factors (e.g., depression, family history of alcoholism). In addition, the profile contained general information about the effects of various BAC levels and tolerance to alcohol.
