School-Family Linked and Online-Offline Combined Tobacco Control Intervention for Adolescents: Protocol for a Cluster Randomized Pilot Trial
By Liu W, Su Q, Cao Y and 9 others.
Abstract
Background
Tobacco use remains a leading preventable cause of disease, yet adolescent-focused tobacco prevention is underexploited. We developed a real-time adaptive intervention that combines school-family collaboration with online-offline delivery (via WeChat mini-programs, games, and curricula) to address adolescents' overlooked role as health catalysts and persistent household secondhand smoke (SHS) exposure.
Objective
This study aims to evaluate the feasibility and effectiveness of this school-family linked and online-offline combined tobacco control intervention in improving adolescents' tobacco-related knowledge, attitudes, and behaviors, reducing student smoking prevalence and household SHS exposure, and assessing implementation process indicators (fidelity, participation, and satisfaction) to inform future scale-up.
