Uncovering the most effective active ingredients of antismoking public service announcements: The role of actor and message characteristics

摘要

Introduction:This study examined whether the appeal of actors (i.e., their likeability and attractiveness) used in antismoking public service announcements (PSAs) interacts with adolescents’ risk of future smoking to predict adolescents’ smoking resistance self-efficacy and whether the antismoking messages in the PSAs further moderate this relationship.
