The Screening to Brief Intervention (S2BI) tool provided by Drugabuse.gov provides a screening tool consisting of frequency of use questions to categorize substance use by adolescent patients into different risk categories. The accompanying resources assist clinicians in providing patient feedback and resources for follow-up. The intended use of this screening tool is meant to be used under a medical provider’s supervision and is not intended to guide a self-assessment or take the place of a healthcare provider’s clinical judgment. The tool can be adminstered by the clinician or the patient under the care/guidance of a clinician.
