Our long term goal is to develop, implement, and evaluate a program to prevent or delay the initiation of alcohol use in young adolescents by increasing protective factors and reducing risk through a family-based brief prevention intervention started in the pediatric emergency department (PED). The primary aims of the proposed developmental study include: (1) To pilot test a prevention intervention in alcohol-naïve adolescents, make necessary revisions, and finalize an intervention manual and (2) conduct a randomized pilot trial comparing the prevention intervention with enhanced standard care. After conducting an open trial of the prevention intervention with 10 adolescents, ages 12-14, and their accompanying parent(s), and refining the intervention, we will use a two-group randomized design to test the hypothesis that the prevention intervention will prevent/delay the initiation of alcohol use significantly more than enhanced standard care only. 100 adolescents, ages 12-14, who present to the PED and their accompanying parent(s)/caregiver will be enrolled into the study. Eligible, assenting adolescents and their consenting parent(s)/caregiver will complete a series of assessment instruments relating to alcohol and other drug (AOD) use, communication styles, parenting styles, and alcohol attitudes and behaviors. Parent/youth family units will then be randomly assigned to one of two conditions: 1) Enhanced Standard Care (ESC) or 2) Brief Targeted Prevention Intervention with Boosters (BTP). The initial session will be comprised of parent-targeted skill building directed primarily at parental monitoring and the importance of parent-adolescent communication as the precursor to successful monitoring. The primary goal of the prevention session will be the mobilization of the parents' own resources to increase communication and monitoring using motivational interviewing techniques. Parents within this condition will also receive periodic brochures and telephone booster sessions at 1 and 3 months to explore parental implementation of the plan from the previous session(s) and make revisions as necessary. Adolescents and parents will then be reassessed six months following their PED visit. Adolescents will also be assessed with monthly, brief, web-based follow-up contacts to determine the status of their alcohol use.
