Young teens (aged 12-14 years) engaging in occasional use of alcohol, cannabis, or tobacco use, or with a family history of SUD, are at increased risk for SUD. Although behavioral-ecological family therapy is effective for prevention, many families face access barriers. Single-session interventions (SSIs) may offer an accessible, low-intensity alternative.OBJECTIVE: This open pilot trial aimed to evaluate the acceptability, feasibility, and potential usefulness of a family-based SSI targeting improvements in family practices that prevent SUD.METHODS: Participants were 9 young teens engaging in occasional SU or with a family history of SUD and their parent. The SSI involved a virtual 2-hour family consultation with a trained family coach. Acceptability was measured via Program Feedback Scale, feasibility via SSI completion rate, and potential usefulness via pre-post changes in parenting self-efficacy.RESULTS: The SSI was acceptable to parents and teens (mean Program Feedback Scale scores ≥3) and feasible (8/9, 88.89% of parent-teen dyads completed the SSI). Among the 8 completing dyads, most participants (13/16, 81.25%) selected Communication and Problem Solving as their primary target for change. Parents reported increases in parenting self-efficacy from pre- to post-SSI.CONCLUSIONS: Findings support the SSI's acceptability and feasibility for young teens at high risk for SUD. A randomized clinical trial is needed to confirm the SSI's acceptability, feasibility, and efficacy, as well as to address potential for delivery by a lay workforce.TRIAL REGISTRATION: ClinicalTrials.gov NCT06538922; https://clinicaltrials.gov/study/NCT06538922.PMID:42809837 | DOI:10.2196/93263
