'In this bulletin, the authors describe 10 guidelines for community supervision professionals who regularly work with underage drinkers. These guidelines are derived from evidence-based practices. They help professionals develop a plan for screening underage drinkers, determine appropriate responses, create a case plan, and provide treatment' (p. 1). These guidelines are: conduct screening for alcohol problems at first and subsequent contacts between underage drinkers and the justice system; assess the youth's risk and need; assess youth for strengths and assets; assess youth for substance abuse problems; determine the most appropriate system-level response and individual-level intervention(s) and develop an individualized case plan; identify each offender's readiness to change and prompt him or her to make positive changes using motivational interviewing techniques; refer underage drinking offenders with alcohol disorders to appropriate alcohol treatment and monitor their attendance and participation; engage family and social support networks in the supervision process; monitor compliance with supervision conditions and case plan expectations; and apply sanctions for noncompliance when necessary, and increase positive reinforcement.
