Interventions

CATCH My Breath (CMB) program for E-cigarette prevention among adolescentsbehavioral

CMB has 4 developmentally appropriate e-cigarette lessons, 20-30 minutes in each of 6th-8th grades. Strategies include small and large group discussions, parent interviews, role-plays, media literacy, and goal setting. E-cigarette focused science and humanities activities (2 per school year) are also provided. An informational tool kit will be provided to parents. Finally, 8 activity-based E-cig PE lessons are intended for either 7th or 8th grades, depending on school calendar. CMB provides study materials to teachers through an online access portal. A site-based management team will oversee program implementation. Teachers in CMB intervention schools will be provided with CMB-specific training for implementing the lessons with fidelity through a one-hour live webinar, offered at multiple times to accommodate teaching schedules. Project staff will meet routinely with participating schools to answer study questions.

The TEA tobacco prevention program is a state-supported program that meets the mandates of the state. It includes TEA developed online lessons and support materials and also includes elements of the CDC Know the Risks e-cigarette prevention program. This can be considered 'usual care'
