Religious Fundamentalism and Racial and Sexual Prejudice: Comparing Religious Fundamentalism Scale and Intratextual Fundamentalism Scale

Many studies indicate a positive relationship between fundamentalism and sexual and racial prejudice. Many of these studies use the Religious Fundamentalism Scale (RFS), the Attitudes Towards Homosexuals Scale (ATHS) and the Manitoba Scale. However, there appears to be overlap between RFS and both ATHS and the Manitoba Scale, unaddressed by the literature. This study looked at possible overlaps between RFS and ATHS and between RFS and the Manitoba Scale that could inflate the correlation statistic of fundamentalism and sexual and racial prejudice. The Intratextual Fundamentalism Scale (IFS), a study without authoritarian or apparent prejudice-overlapping items, was also tested for overlap. Results showed two-factor structures—namely fundamentalism and prejudice—with only two items loading to the opposite factor. However, there were many near-zero item loadings. The discussion suggests ways to change these items to increase factor loadings and to change overall measures construct validity. The correlations between fundamentalism and sexual prejudice were not significant before modifying the measures and were small and negative after modifying (modifying measures means removing all crossloaded and near-zero loaded items). The modified fundamentalism and sexual prejudice measures correlations do not follow the literature. This may be due to the sample including sexual orientation minorities and a majority of atheist, agnostic, or ‘nothing in particular’ affiliations. The correlations between fundamentalism and racial prejudice were medium and positive before modifying and were small and positive after modifying. This falls in line with the literature of small and medium positive correlation statistics.
