I am a political scientist, interested in political psychology, quantitative and qualitative methods, comparative electoral behaviour, and social/collective identity.
My doctoral research, under the supervision of Prof. Dr. Kai Arzheimer, focused on the measurement of party identification within the social identity approach. I showed that the existing measure does not tap negative or multiple party identifications, although these phenomena are theoretically plausible. Drawing on current social identity research, I adapted two measurement instruments, the Identification with a Psychological Group (IDPG)-scale by Mael and Tetrick (1992) and the Single-Item Measure of Social Identification by Postmes et al. (2013) for the measurement of party identification. These measures were included in a three-wave online survey in 2013 and in the GESIS-Panel, Wave 9 and 15. By employing the concept of construct validation, I could confirm the validity of these measures. I received my Ph.D. in April 2016.
