A Short Scale for Measuring Political Secularism

Abstract

As religiousness is declining across democracies, scientific interest in secular orientations and their political implications is growing. One specific and particularly important aspect of secular attitudes is political secularism. Political secularism is not merely the absence of religiousness, but rather a world view which holds that religious beliefs should play no role in politics. While there are hundreds of survey instruments that measure the strength and content of religiousness, there is no comparable measure that taps into political secularism. In this research note, I briefly review the concept of political secularism and present a cluster of items which target it. Utilizing data from four large population representative samples taken from the eastern and western states of Germany, I use confirmatory factor analysis to show that these items form a short but internally consistent scale. This scale also displays convergent and discriminant validity. It may be readily used in future surveys.
