On the basis of theoretical work reported elsewhere, scales were developed
with the goal of measuring some phenomena associated with Christian postfor
mal thought development. These scales were used in 3 studies. The first exa
mined scale intercorrelations; the second compared scores on the scales bet
ween evangelical and nonevangelical college samples; the third was a 4-year
longitudinal study of a group of evangelical college students. Significant
differences in scale scores were found in the evangelical and nonevangelic
al college samples and across the 4 years of the longitudinal study, which
showed that individualism and relativism are not necessary concommitants of
maturing cognitive development within the Christian community, calling int
o question the reliance on exclusively secular theories for understanding e
arly adult development of Christians.
