Abstract:

National identity is an elusive and very difficult to attain and to measure concept. Several attempts have been made to develop a global set of items able to capture the different (and normally presented as opposed) tokens of national identities: civic and ethnic, primordial and constructed, etc. This paper presents an attempt to develop a set of good survey items to measure Spanish national identity, and the results of the evaluation of it. First we introduce the process by which we used Q-Methodology to create a set of 12 items that were included in a survey questionnaire that was used by the Centro de Investigaciones Sociológicas (CIS) to collect data from a representative sample of Spaniards (CIS-2667). Secondly we use that data to explore the dimensionality and the quality of the items proposed using Mokken and Rasch Models.
