Religious Fundamentalism: An Empirically Derived Construct and Measurement Scale

Abstract

Items were generated to explore the factorial structure of a construct of fundamentalism worded appropriately for Judaism, Christianity, and Islam. Results suggested three underlying dimensions: (a) External versus Internal Authority, (b) Fixed versus Malleable Religion, and (c) Worldly Rejection versus Worldly Affirmation. The three dimensions indicate that religious fundamentalism is a personal orientation that asserts a supra-human locus of moral authority, context unbound truth, and the appreciation of the sacred over the worldly components of experience. The 15-item, 3-dimension solution was evaluated across Mexican ( n = 455) and American ( n = 449) samples. Fit indexes point out the viability of the new inventory across these two samples henceforward referred to as the Multi-Dimensional Fundamentalism Inventory (MDFI). Additional validity tests supported that the new inventory was negatively correlated with participants’ integrative complexity in a religious domain–specific way.
