Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The iSTART intervention is a 30-day substance prevention web-app whereby students complete five weekly interactive modules using a smart device or computer. Each module is approximately 15 minutes long, and focuses on a select substance: (i) alcohol, (ii) marijuana, (iii) nicotine, (iv) prescription drugs, and (v) illicit drugs. The modules are based on key theoretical constructs, behavior change strategies, and practical module components: attitudes (knowledge), perceived susceptibility (risk perceptions), subjective norms (normative re-education), and self-efficacy (refusal skills). This intervention will be evaluated via a time series design using a sample of 600 students randomly assigned to either the intervention, comparison, or control condition at a public institution in southern California.
