Universität Erfurt


Welcome to the Psychology and Infectious Diseases Lab (PIDI Lab)! 

Prof. Dr. Cornelia Betsch and her team work on understanding principles of health behavior by applying a judgment and decision making and strategic interaction perspective to infectious disease control - especially with regard to the vaccination decision and prudent use of antibiotics.

At the same time, they believe in the necessity to make research findings usable. That’s why this team is also involved in creating online materials for health organizations (such as the Europen Centre for Disease Prevention and Control or the Bundeszentrale für gesundheitliche Aufklärung) or in projects with authorities such as the World Health Organization, Regional Office for Europe, or the Thuringian Ministry of Health.This combination of high understanding and high usability of research has been labelled “Pasteur’s Quadrant” (Stroke, 1997). We would like to follow this luminous tradition by striving for both high understanding and high usability to contribute to the attainment of public health goals.

Current research projects

Reducing negative effects of communicating vaccine safety events – Erkenntnistransfer-Projekt SAFECOMM
This knowledge transfer project builds on the results of two DFG-projects, which have shown that narrative reports of vaccine-adverse events have a strong distorting effect on the perception of vaccination risks and the vaccination intention. The application partner is the Paul-Ehrlich-Institute (PEI). With Frank Renkewitz, University of Erfurt. This project is funded by the DFG. Doctoral student: Lisa Steinmeyer.

Vaccination as strategic behavior: Vaccine hesitancy
In this project with Robert Böhm (RWTH Aachen University) we develop an interactive vaccination game to test the idea that vaccination decisions are also strategic interactions: when it is individually rational not to vaccinate, but collectively necessary to reach elimination goals – which factors make people vaccinate? Which factors invite free-riding? This project is funded by the DFG. Doctoral student: Lars Korn (Erfurt) and Nicolas Meier (Aachen).

Impfen 60+: Influenza and pneumococcal vaccination and sepsis prevention
In this joint project with the Robert Koch Institute, the Universitätsklinikum Jena and Lindgrün GmbH we will create and evaluate an evidence informed intervention to address vaccine hesitancy regarding influenza and pneumococcal vaccination in the elderly. We will draw upon the 4C model of vaccine hesitance (Betsch, Böhm & Chapman, 2015) and evaluate the intervention against vaccine uptake as well as conduct a cost effectiveness study. Funded by the German Ministry of Education and Research (BMBF). More info here: www.impfen60plus.de. Doctoral students: Dorothee Rauber, Sarah Eitze, Philipp Schmid (psychology), Winja Weber, Anne Reinhardt (communications), Nora Küpke (lab manager).

Nudging health-care personnel to increase the uptake of influenza vaccination
In this project with Prof. Ansgar Lohse, Universitätsklinikum Eppendorf, we aim at analyzing the reasons for vaccine hesitancy in healthcare workers. Furthermore, we design nudges to increase healthcare workers’ seasonal influenza vaccine-uptake. The project uses a combination of laboratory experiments and field experiments to optimize the validity of results and derive practical conclusions for the implementation of nudges in a clinical setting. This project is funded by the German Ministry of Education and Research (BMBF) via the DZIF (Deutsches Zentrum für Infektionsforschung).
