In this workshop, Dr. Winters begins by providing the rationale and utility for brief interventions for adolescent substance use problems. He then goes into detail about the brief intervention he developed, "Teen Intervene." In addition, Dr. Winters covers assessment tools useful for motivational enhancement and assessing teen drug/alcohol use, such as the Treatment Improvement Protocol (TIP) Series. Motivational enhancement techniques include assessing stage of change and non-confrontational interviewing. Lastly, he demonstrates how to administer the three-session intervention and presents a case example.
