Feasibility of the Yuva Sath intervention as measured by peer counselor fidelity to the intervention protocol will be determined by independent observer fidelity checklists. The checklist will score content delivery on a 3-point ordinal scale (1=no key content covered to 3=all key content covered), and peer-navigator actions (i.e., identification of barriers; generation of solutions) on a 5-point Likert scale (1=not at all to 5=very much). The intervention will be deemed to be feasible if 80% of the sessions addressed key Life-Steps module content and employed flexible problem-solving

Feasibility of the Yuva Sath intervention as measured by attendance in the first four sessions will be calculated as a proportion: participants who completed the first four sessions of the total 6 sessions of the intervention/ All participants in the intervention arm. The intervention will be deemed to be feasible if at least 75% of participants completed the first four sessions

Feasibility of the Yuva Sath intervention as measured by completion of the 3 month session will be calculated as a proportion: participants who completed the 3 month assessment / All participants in the intervention arm. The intervention will be deemed feasible if at least 60% of participants completed the 3-month assessment

Acceptability of the intervention as measured by the overall satisfaction of participants rated on a 5-point Likert scale (1=not at all to 5=very much). The intervention will be deemed acceptable if at least 75% of the participants rate >=4 on overall satisfaction

Substance use treatment engagement as measured by the average number of MOUD visits each month over a 6 month period will be compared between the intervention and control arms.
