We examined associations between two psychological constructs, analytic cognitive style and the personality facet ‘Openness toExperience’, and several dimensions of religiosity: religious affiliation, strength of faith and spiritual epistemology. In arelatively large (N = 1093), older community sample (M = 55.4 years), analytic cognitive style was associated with a lower probability of affiliating with a religious denomination and a higher probability of possessing strong religious faith. Overall, openness was also associated with a lack of religious affiliation but was positively related to possessing a spiritual epistemology. A path-analytic model revealed that openness had a positive relationship to both faith and religious denomination that was mediated by spiritual epistemology, but negative direct relationships with religiosity after the meditational effects were taken into account. Taken together, these results extend previous findings on the effect of cognitive style on religiosity and provide a new perspective on the complex relationship between cognitive and personality factors and different dimensions of religiosity.
