Religiosity and moral intelligence are recognized as important psychological resources that support an individual’s functioning in the areas of life meaning, values, and ethical decision-making (Lennick & Kiel, 2005). The literature also high lights their role in shaping spiritual well-being, understood as a sense of harmony, meaning, and inner coherence, which is confirmed by research on the relationship between religiosity and mental health (Koenig, 2012). The aim of the study was to determine the relationship between religiosity and moral intelligence and spiritual well-being, and to examine their role as predictors of spiritual well-being. A sample of 250 individuals aged 18–28 (M = 20.26, SD = 1.65) was surveyed. The study utilized the Duke University Religion Index (DUREL, Koenig, &Büssing, 2010), the Spiritual Well-BeingScale (SWBS, Paloutzian, &Ellison, 1982), and the Moral Intelligence Scale (Dacka, &Noworol, 2025). The results indicato that spiritual well-being has varied determinants depending on the dimension analyzed. Its general aspect shows a significant relationship only with internal religiosity; religious well-being is significantly associated with non-organizational religious activity; whereas the existential dimension is characterized by a more complex profile of relationships, encompassing both religiosity and selected components of moral intelligence, including negative associations. The obtained results highlight the importance of considering religiosity and moral intelligence in explaining the determinants of spiritual well-being and indicate the need for further research on their relationships.
