简要总结
Rates of adolescent vaping are increasing rapidly. Current high school student use of electronic vaping products (EVPs) rose from 1.5% in 2011 to 20.8% in 2018 - an increase from 220,000 to 3.05 million adolescent users. Effective, school-based interventions are urgently needed to protect adolescents from initiating or continuing use of electronic vaping products (EVPs). This study leverages a state-supported prevention initiative to test the effectiveness of a promising intervention that trains 8th-9th grade student peer leaders to deliver school-wide vaping prevention campaigns with ongoing adult mentoring. If study hypotheses are supported, the study will provide the first evidence of a school-based preventive intervention that reduces adolescent vaping behaviors, as well as insight into how peer communications can be harnessed to prevent vaping.
详细描述
Above the Influence of Vaping (ATI-V) trains peer nominated 8th-9th grade Peer Leader, and adult advisors. Peer Leaders learn skills and implement school-wide prevention campaigns informed by communication science.New York State has provided funds to support schools to implement ATI-V but no funds for efficacy research. With support from New York State and a strong team of investigators, our project has two aims:
Aim 1. Efficacy. The primary aim of this study is to determine ATI-V impact in preventing vaping use (past 30 days any vaping, nicotine vaping, and regular use). Using an RCT design, 20 schools will be assigned to (a) immediate ATI-V, or (b) wait-list for ATI-V training after 24 months. Approximately 3,800 8th graders will be enrolled and followed for assessments in fall 8th grade, spring 8th grade, spring 9th grade, and mid-year 10th grade. We will test for which students ATI-V is most effective and in what school contexts (school climate).
Aim 2. Mechanism. The second aim of this study to test the hypothesized mechanisms of ATI-V impact. To accomplish this aim we will conduct statistical analyses of a mediation model to determine (a) whether ATI-V improves students' perceptions that vaping is unacceptable to their peers (anti-vaping norms), connections to supportive adults to address EVP concerns, and social influence of non-vaping students; and (b) whether the impact of ATI-V on reduced vaping behavior is mediated by these improvements.
