The Bielefeld-Based Cross-Cultural Study on Deconversion and Fundamentalist Biographies

The Bielefeld-Based Cross-Cultural Study on Deconversion has focused on deconversions from a variety of religious affiliations in the U.S.A. and Germany: from all kinds of religious traditions and organizations, including mainstream religious organizations and churches, as well as, new religious and fundamentalist groups. The team of researchers had an international and interdisciplinary profile and included psychologists, sociologists, and theologians. In the years from 2002 to 2005, a total of 1,196 research participants have been interviewed. The core of the study are about one hundred deconversion narratives (50% from U.S.A. and 50% Germany). Results are published in a book (see Publications on this page).

Here on the Internet we present, besides a brief Overview and an outline of our Methods, the most important qualitative and quantitative results. But this web site is also the location to present material such as tables, figures or interview texts in full length for which there is not enough space in the book.

The presentation is a selection of contributions to various conference, including APA 2009 in Toronto and IAPR 2009 in Vienna.

The Bielefeld-Based Cross-Cultural Study on Deconversion has researched in transatlantic comparison and in much greater detail what has begun as study of Christian-fundamentalist biographies for the Enquete Commission on So-called Sects and Psychogroups” of the 13th German Parliament.
