Does the 'CATCH My Breath' Vaping Prevention Program Prevent High School Students in Ontario, Canada From Starting to Vape?

CATCH My Breath (CMB) is a school-based vaping prevention curriculum based on best practices from earlier prevention studies that works by fostering social competence and social influence resistance skills. The curriculum design and content targets two key constructs of Social Cognitive Theory: self-efficacy and behavioural capacity (i.e., knowledge and skills). The curriculum provides students with knowledge of why and how to resist vaping. It is delivered through two 60-minute lessons by a trained Public Health Unit presenter. The curriculum lessons provide information about: 1) the physical, mental, and addiction risks associated with vaping, 2) social norms of vaping (e.g., most youth don't vape), 3) media literacy (e.g., how to recognize and decipher marketing of vapes), 4) strategies to resist and avoid vaping, 5)school and provincial policies about vaping. To solidify the content, in-class activities allow students to discuss what they are learning and practice refusal skills.
