Summary

The goal of this study is to modify a smoking prevention program for 5th and 6th grade students to also target vaping e-cigarettes. Aims were to modify the program along with associated materials and to conduct a trial with 5th grade students in the school setting to see how well the updated program worked. Students either participated in the four-week computer based program or continued with their usual tobacco prevention curriculum. This study showed that students who received the computer program reduced their intentions and willingness to use e-cigarettes or smoke in the future more than did students who used their usual tobacco curriculum.

Detailed description

Given the increase in prevalence of e-cigarette use among youth, investigators modified a smoking prevention program to not only target smoking but also vaping e-cigarettes. Investigators conducted a pragmatic randomized trial with 5th grade students in schools across Arizona and Oregon to evaluate the effectiveness of the updated program in a "real-world" setting. Forty-five schools were randomized to the intervention condition, wherein students used the updated version of Click City®: Tobacco, or the control condition, wherein students were taught their usual tobacco prevention curriculum. Students in the intervention schools decreased their intentions and willingness to use e-cigarettes and cigarettes significantly, as compared to students in control schools. The intervention also significantly changed all etiological mechanisms. The effects on all outcomes of the intervention were similar as a function of state (Arizona vs Oregon), gender, ethnicity (Hispanic vs not Hispanic), and historical timing (prior to school closures in 2020 vs after schools re-opened in 2022). The intervention was also more effective for at-risk students, as defined by student's previous tobacco use, current family use and/or high in sensation seeking. Close to 90% of the students completed the entire program, and most completed it in 3 to 4 weeks, the expected time frame. The effectiveness of the updated Click City®: Tobacco was demonstrated in a "real world" setting and findings suggested that all students can potentially benefit from the program.
