Onderzoek Bevrijdingsfestivals 2014

Date: Data were collected on 5 May 2014 (the most recent Liberation Day in the Netherlands) on five Liberation Festivals (Amsterdam, Assen, Utrecht, Wageningen and Zoetermeer). When choosing which festivals to study, we made sure that all regions were represented (studies demonstrated that in the Netherlands regional factors influence individual attitudes see e.g. Savelkoul, Scheepers, Tolsma, & Hagendoorn, 2010). All festivals were visited by two or three interviewers.

These interviewers received clear instructions on the goal of the study. All interviewers wore clothes with symbols of the university and received an interviewer identification card with the logo of the university and the organization responsible for organizing the two commemoration days in the Netherlands (National Committee 4 and 5 May). The questionnaires were also printed on official paper of the university.

This made sure that the respondents saw that these interviewers represented official institutions. The respondents filled out the questionnaires themselves. It is known that self-administration lowers the chance of social desirable answering patterns (see e.g. Tourangeau, 1996).

In general the level of cooperation was high and we received the feedback that the interviewers as well as the respondents liked participating in this study. It took about ten minutes to complete the questionnaire. In total 1117 respondents filled out the questionnaire.

Data is available in both SPSS (.sav) and STATA (.dta) formats.
