Population-Based Study Examining the eHealth Literacy of the Populations in Flensburg and Tallinn Presentation of a study design Anna-Lena Pohl1 1Institute for eHealth and Management in Health Care, Flensburg University of Applied Sciences, Germany 1. Introduction The eHealth master course at Flensburg University of Applied Sciences and students of Tallinn University of Technology are planning a joint student project, designed as a population-based study, to examine the level of eHealth literacy in the two cities. The eHealth literacy of German and Estonian populations has not been evaluated before. The study is a starting point to collect data and analyse the situation in Flensburg and Tallinn. The outcome of the study will be published and might serve as a basis for further research. The questionnaire will be based on an already tested and often used measurement instrument. Additionally, the use of parts of the Digital Health Literacy Instrument is pioneer work, since this measurement scale was only published in January 2017. It is not tested and validated by any additional study yet. 2. Study Design The target groups are the populations in Flensburg and Tallinn, aged 18+ years. The selection of participants will be performed randomly. The total number will be 1 000 completed interviews. The survey will be performed using computer-based telephone interviews. The answers will be documented with the use of software. Copyright © 2017 by the paper's authors. Copying permitted for private and academic purposes. In: H. Gilstad, S. Khodambashi, J.
