In 'Deconversion' Streib and colleagues (2009) set out to examine the overlooked realm of religious deconversion: the active process by which individuals disaffiliate from religion. The 'Bielefeld-Based Cross-Cultural Study of Deconversion' consists of a mixed methods and cross-cultural approach to religious change in the USA and Germany. This work is a thoughtful consolidation of theoretical, empirical, and integrated methodological approaches to gaining a more comprehensive understanding of the trajectories and biographical narratives of deconverts.
