The aim of the PhD project is to understand how the effects of health interventions are mediated or moderated by interpersonal communication.

To this end, we examine how teachers communicate about the health intervention with students, how students communicate with classmates and respond to the communication of their teacher, and how the effects of the health intervention depend on interpersonal communication by teachers and students.

Another aim of the project is to improve the health intervention based on the knowledge of content of interpersonal communication.
