‘What matters to Andrew’. The problem of premissary relevance in automated health advisors. Insights from pragma-dialectics

Objective

To influence health behavior, communication has to be relevant on an individual level and, thus, fulfill the requirement of premissary relevance. This paper attempts to enrich the design of automated health advisors by, first, reviewing main solutions to the challenge of premissary relevance found in the literature and, second, highlighting the value in this field of the theory of argumentation known as pragma-dialectics.

Methods

A conceptual paper grounded in persuasion research and argumentation theory.

Results

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.

Conclusion

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.

Practice implications

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.
