Study 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.

Primary Outcome

Measured by two items, assessing the student's intentions regarding vaping e-cigarettes as a teen or as a grown-up. Responses were on a five-point scale ranging from "definitely not" (1) to "definitely will" (5). The scale was created by summing the two items with potential range from 2 to 10. A higher score means a worse outcome.
