Repke, Lydia

External Collaborator


Lydia Repke is an external collaborator at the Research and Expertise Centre for Survey Methodology (RECSM). She is currently working on the comparability of measurement instruments and the statistical testing of their equivalence at the Survey Design and Methodology (SDM) department of “GESIS – Leibniz Institute for the Social Sciences” in Mannheim, Germany, where she is embedded in the teams Cross-Cultural Surveys and European Social Survey.

Lydia received her PhD from the Universitat Pompeu Fabra (UPF) in 2017 in the field of cultural psychology supervised by Verònica Benet-Martínez. Her dissertation – entitled "Multiple Cultural Identifications, Personality, and Social Networks“ and funded by the German National Academic Foundation – adds to the adequate understanding of the acculturation processes affecting immigrants and their descendants by not merely focusing on individual characteristics but by also including actual intercultural contact. In particular, Lydia explored the dynamic interplay between how bicultural individuals manage their multiple (and sometimes conflictual) cultural value systems and identifications, and the changes in their personal social networks. Social network analysis, cluster analysis, multiple regression analysis, agent-based modeling, and correction for measurement error are some of the applied methodologies.

Lydia was part of various research groups at UPF: the Behavioral and Experimental Social Sciences (BESS) group, the Advanced Survey Quality Methods (ASQME) group, the Management and Behavioral Research Breakfast Seminars group, and the Interdisciplinary Research Group on Immigration (GRITIM).

Lydia holds a MA and a BA in Political and Administrative Sciences from the Universität Konstanz (Uni KN), Germany (2011, 2009), and a MSc for Research in Political Science from UPF, Barcelona (2011). During her studies in Germany, she worked as a tutor at the Chair of International Politics (Gerald Schneider) and as a research assistant at the Chair of Political Science and International Politics (Dirk Leuffen) as well as at the Chair of Management, Especially for Strategy and Leadership (Sabine Boerner). Further, Lydia was a visiting student at Boğaziçi Üniversitesi in Istanbul, Turkey (2008/2009).

Her research interests include: personal social networks, bi-/multiculturalism, cultural identifications, acculturation, migration, and survey methodology (questionnaire design, data quality, correction for measurement error, cultural and linguistic effects, measurement equivalence).
