A conceptual paper grounded in persuasion research and argumentation theory.
Automated health advisors enable argumentative exchanges with users. But there is a need to design these systems as to make them work in an audience-centered perspective. The theory of pragma-dialectics can be used to analyze the factors that favor or hinder the agreement of users to engage in certain health behaviors, and to identify argumentation strategies targeted to behavior change.
Pragma-dialectics can be used to enhance the design of automated health advisors as it operationalizes the dialogical nature of the reasoning process that can influence health behavior.
Premissary relevance is a challenge of communication for health promotion at large that can be promisingly addressed through synergies among persuasion research, argumentation theory and Artificial Intelligence.
