title = "Measuring party positions in Europe: The Chapel Hill expert survey trend file, 1999–2010",
abstract = "This article reports on the 2010 Chapel Hill expert surveys (CHES) and introduces the CHES trend file, which contains measures of national party positioning on European integration, ideology and several European Union (EU) and non-EU policies for 1999−2010. We examine the reliability of expert judgments and cross-validate the 2010 CHES data with data from the Comparative Manifesto Project and the 2009 European Elections Studies survey, and explore basic trends on party positioning since 1999. The dataset is available at the CHES website.",

note = "Funding Information: This research note presents information about trends in party positioning and assesses the validity and reliability of the longest running data collection project compiling expert party placements in the European context. As more researchers use CHES data to examine party competition and political representation (e.g. Adams et al., 2012 ; Bakker et al., 2012 ; Jolly, 2007 ; Karreth et al., 2013 ; van de Wardt, 2012 ), establishing the validity and reliability of expert placements is of key importance. Our results suggest that CHES data display quite high levels of inter-expert reliability and considerable common structure with different measures. This is good news for scholars aiming to examine the positions of parties on a variety of ideological and policy dimensions in a longitudinal and cross-national perspective.
