The association between smoke-free school policies and adolescents' anti-smoking beliefs: Moderation by family smoking norms

摘要

Background: Smoke-free school policies (SFSPs) may influence adolescents' smoking through the development of anti-smoking beliefs. We assessed which types of anti-smoking beliefs (health, social and societal) are associated with SFSPs and whether these associations were different for adolescents in smoking permissive versus prohibitive families.
