We aimed to examine whether young adults practicing Buddhism have elevated levels of psychological resources and specific personality traits compared to Catholics and Atheists. We recruited 184 participants: Soka Gakkai Buddhists (n = 60); non-practicing Roman Catholic Church believers (n = 62); Atheists (n = 62). We found that the Buddhists have higher optimism than both Catholics and Atheists. They also have higher self-efficacy and self-esteem than Catholics and higher perceived social support than Atheists. Concerning global personality factors, they are more extraverted than the other groups, and they are less tough-minded than Catholics. Differences also emerged relating some primary personality factors. Since we did not find differences between Catholics and Atheists about psychological resources, we speculate that religion alone does not provide an efficacious source of psychological resources; it could be that religious practice is determinant.
