<qa>  What is the focus group feedback that will help youth understand the potential of implementing a brief1. Explore the feasibility of adapting a brief intervention for high-risk youth in a primary care PC setting. We will determine barriers and facilitative factors associated with implementing a brief intervention in a PC setting through focus groups with high-risk youth n16, parents n8, and clinicians n8. Intervention content will be established through modifications of our previous brief intervention work in school and hospital settings and from focus group feedback from adolescents, clinicians, and parents. We anticipate the intervention will take 15 minutes and will be implemented by a clinician e.g., nurse in the PC setting. The intervention will emphasize motivational techniques and will address a variety of substances, including marijuana, inhalants, alcohol, and cigarettes. We will pilot test the intervention with a small sample of high-risk youth n10 to obtain feedback to discern whether the intervention was difficult to implement e.g., time constraints, comfort level and how youth felt about receiving feedback from their clinicians on their substance use e.g., was it helpful? What other topics would they have liked to discuss?. We will modify content based on this feedback.
