the full set of demographic, behavioral, and attitudinal variables
were calculated. To ensure that these correlations were not con-
founded by extraneous factors, they were determined first after
the other spiritual/religious variable was partialled out and then
after the other spiritual–religious variable and the full set of

variables. In general, there was a wide range of significant corre-
lations (range = .07–.52), and those that were weak (e.g., .07)
were nonetheless significant because of the large sample size.
Among the demographic factors, self-perceptions of spirituality,
after adjustment for religiousness, were associated with being
female, younger, and better educated. In contrast, self-percep-
tions of religiousness, after adjustment for spirituality, were as-
sociated with being in an ethnic minority, older, and less well
educated; living in a smaller town; and living in the South.
Self-perceptions of spirituality were inversely correlated with
being Catholic and positively correlated with having no religion,
whereas self-perceptions of religiousness were correlated with
being a conservative or moderate Protestant and inversely corre-
lated with having no religion.
After adjustment for these sociodemographic differences,
self-perceptions of spirituality were correlated significantly
with all of the religious activities. However, these correlations
were weaker than the corresponding correlations with religious-
ness. The only exceptions to this were for meditation and the
Spiritual subscale of the Daily Spiritual Experience Scale,
which were both more strongly related to self-perceptions of
spirituality (rxy = .28 and .38, respectively) than they were to
self-perceptions of religiousness (rxy = .09 and .20, respec-
tively). Among the indexes of well being, self-perceptions of
spirituality were inversely associated with cynical mistrust (rxy =
Next, we moved to an examination of the correlates of the
four-level spiritual–religious typology in which information
about both self-perceived spirituality and self-perceived reli-
giousness was combined. To examine sociodemographic corre-
lates of the four-level typology, we assumed that the direction of
causality was that these factors predict placement on the
typology rather than the reverse. Consequently, we modeled the
association by regression of the typology (the dependent vari-
able) on the sociodemograhic factors (the independent vari-
ables) using multinomial logistic regression. This procedure is
akin to logistic regression in that it computes the likelihood of
being in one category of the dependent variable versus another,
based on levels of the independent variables. However, it differs
from logistic regression in that it allows the dependent variable
to be more than two categories. Because our greatest interest is
in understanding spirituality, we calculated the odds for these
analyses with the spiritual and religious group as the referent
and compared it to the other three groups.
In the final stage of the analyses, we posited that other fac-
tors, such as behaviors and attitudes, were associated with the
spirituality–religiousness typology. Consequently, we modeled
these associations by generating mean scores of the attitudi-
nal–behavioral items based on levels of the typology. Given that
levels of the typology were influenced by sociodemographic
confounders, we adjusted first for these factors. All analyses
were completed with the PROC CORR, PROC GLM, and
PROC CATMOD procedures within the SAS software package.
–.08), and self-perceptions of religiousness were associated
with better self-rated health (rxy = .07). Among the beliefs and
values, spirituality was inversely related to being conservative
(
rxy = –.08), in contrast to religiousness, which was positively re-
lated to being conservative (rxy = .14). Spirituality was unrelated
to being intolerant, in contrast to religiousness, which was asso-
ciated with the Intolerance total score (rxy = .11) and intolerance
on the Atheist, Militarist, and Homosexual subscales (rxy = .12,
.10, and .13, respectively).
RESULTS
Our next step in the analyses was to examine the correlates
of self-perceptions when information about spirituality and reli-
giousness was combined to form the four-group typology. Table
Table 2 presents a description of the 1,422 respondents that
were evaluated in the spirituality–religion panel of the 1998
GSS. The average age was 45.6 years, with 68% of participants
falling within the approximate range of 28 to 62. The population
was 54.5% female, 79% White, and 47.4% married, and 16%
had less than a high school education. Approximately 34.9%
lived in an urban area, and 36.3% lived in the South. These char-
acteristics essentially mirrored those of the overall United
States, where according to the 2000 census or the 2000 Current
Population Survey (19), 50.9% were female, 75.1% were White,

focuses on the sociodemographic variables and presents the
independent odds of having each of the variables, with the spiri-
tual and religious group as the referent. Relative to this referent,
the spiritual-only group had an 80% lower odds of being minor-
ity, a 46% lower odds of being from the South, and a 52% lower
odds of being married. In addition, the spiritual-only group was
younger and better educated. These demographic differences
were less extreme when the religious-only group was compared
to the referent and more extreme when the neither spiritual nor
religious group was compared to the referent. The only excep-
tion to this was the educational level of the neither spiritual nor
religious group, which was lower than the referent and consider-
ably lower than the spiritual-only group.

2.9% were married, and 21.5% had less than a high school edu-

With regard to religious activities, 80% of the sample was
either Protestant (54.5%) or Catholic (25.5%), and 13.5% re-
ported that they had no religion. Approximately 31.6% attended
church or services nearly every week or more, 54.1% prayed at
least once a day, and 21.8% meditated at least once a day. This
was comparable to religious activity in the U.S. population (20).
Self-perceptions of spirituality and of religiousness were
