The aim of this article is to further knowledge of the explanatory processes of narrative persuasion in the field of health communication, using data obtained in a research study of entertainment-education based on audiovisual fiction. Participating in the study were 208 young persons between the ages of 14 and 20, randomly distributed to three different groups. Each of the groups was exposed to a different episode of the Colombian television series Revelados, desde todas las posiciones. The results showed that greater identification with the main character of the episode transmitting a prevention message was associated with greater cognitive elaboration, which in turn led to more favorable attitudes toward the topics addressed. However, counterarguing was not observed to play a significant mediating role. The findings of this study allow us to conclude that getting people to think and reflect can help persuade them, which suggests that narrative persuasion models and dual models of rhetorical persuasion can be compatible in certain contexts, such as when messages are designed in such a way that characters make explicit arguments that endorse a prosocial message through dialogues.
