ABSTRACT

The emerging adulthood (EA) phase is widely recognised by scholars as a period marked by complex dynamics in religious behaviour, characterised by exploration, openness, and reduced formal participation in religious rituals. During this phase, engagement in religious activities tends to decline while the risk of mental health disorders increases. Although some studies suggest that religiosity positively influences mental health, others indicate that it can also negatively impact mental well-being in emerging adults. This study aims to explore the relationship between religiosity and mental health in emerging adults, identify mediating variables between these two factors, and examine additional influences on this relationship. A Systematic Literature Review was conducted using predefined inclusion and exclusion criteria, with data from Scopus, Taylor and Francis, and JSTOR databases. The findings reveal that religiosity is associated with improved mental health outcomes, such as reduced depressive symptoms and increased life satisfaction, contributing to the Sustainable Development Goals (SDGs), particularly health and well-being. Additionally, self-regulation, life goals, and social support are key mediating variables linking religiosity to positive psychological adjustment. Other influencing factors include gender, intrinsic versus extrinsic religiosity, and the degree of religious internalisation.
