EDUCATION AND SCIENTIFIC KNOWLEDGE IN EUROPEAN SOCIETIES. EXPLORING MEASUREMENT ISSUES IN GENERAL POPULATION SURVEYS

Summary/Abstract: The paper analyzes indicators of scientific knowledge and health knowledge currently available in population surveys and discusses their dimensionality, with particular reference to DK answers. Multiple correspondence analysis is used to identify a satisfactory data reduction strategy, in the Eurobarometer 63.1 2005 and STISOC 2009 surveys. Results support the relevance of an acquiescence response style factor and of a DK response style factor. A bi-dimensional factor model for the negative indicators, including a substantive knowledge factor and a DK style factor seems to offer the most meaningful utilization of the scientific knowledge items.
