Primary Outcome Measures:
Secondary Outcome Measures:

  • Frequency of marijuana use in the past 12 months, measured using the S2BI Screening Tool. [ Time Frame: 12 months post intervention ] [ Designated as safety issue: No ]

    We will compare changes frequency of marijuana use in the past 12 months between the intervention and treatment as usual groups.

  • Perceived risk of harm of substance use [ Time Frame: 12 months post intervention ] [ Designated as safety issue: No ]

    We will compare self-reported perceived risk of harm of substance use between intervention and TAU groups using Monitoring the Future questions.

  • Medication Adherence measured by self-report [ Time Frame: 12 months post intervention ] [ Designated as safety issue: No ]

The proposed project is a randomized control trial to assess the efficacy of an SBIRT model tailored to youth with chronic medical conditions. This trial is being built into a larger, longitudinal cohort study to assess whether a set of brief, substance specific questions can accurately predict adolescent substance use outcomes when compared to more lengthy, criterion standard assessment questions, in cross-sectional and prospective analysis. The first component of the project will consist of pre-testing an assessment battery and brief electronic intervention with a small sample of 14-17 year old youth. In the second component the investigators will randomize consented eligible participants into intervention or control arms of the study and administer the 1) Baseline Assessment Battery and the 2) Brief Intervention OR Treatment as Usual (TAU). In the third component the investigators will follow up with all participants at 6 and then 12 months after study entry to reassess rates of substance use through follow up assessment batteries.

At baseline, the investigators will also attempt to enroll parents of all participants who are present at the time of enrollment. The investigators will separately consent and administer a brief assessment battery to parents to assess their knowledge and attitudes around substance use, as well as opinions and attitudes regarding other health and risk behaviors.
