Arrogant or caring? Influence of transactive communication in interprofessional learning on knowledge gains and stereotype changes.

In interprofessional peer tutoring, medical students and physiotherapy trainees teach and practice examination techniques and work out profession-specific similarities and differences. In small interprofessional groups, we investigated the influence of transactive communication - alternately referring to and building on the statements made by the dialogue partner in the process of conveying information - on knowledge gains and changes in stereotypes of the other profession. A total of 132 medical students and 48 physiotherapy trainees divided into 24 small interprofessional groups indicated the extent of their stereotypes of the other profession before and after the practice session, as well as their perceived increase in knowledge. They evaluated the group work and the perceived intensity of transactive communication. We used regression analyses to test the hypotheses. The intensity of transactive communication in the physiotherapy trainees was positively related to knowledge gains in the medical students. However, this did not apply to the knowledge gains in physiotherapy trainees. With regard to stereotype changes, the intensity of one's own transactive communication unexpectedly turned out to be a significant, albeit weak, influencing factor: The more intensive one's own transactive communication was, the more negative the stereotypes of the other profession became. Transactive communication in interprofessional groups can improve the exchange of knowledge in peer tutoring and bring about changes in stereotypes. Measures to improve transactive communication, e.g. training sessions or specific communication exercises, could help to improve the effectiveness of interprofessional learning.
