Exploring two approaches to an existential function of religiosity in mental health

Recent research demonstrates beneficial associations between religiosity and measures of mental health. In this study, we examined whether religiosity benefits mental health (a) by limiting the negative impact of existential concerns, and (b) by enhancing purpose in life. Three hundred fifty-three undergraduates completed the following measures: Scale for Existential Thinking, Purpose in Life Test, Religiousness Measure, Center for Epidemiologic Studies Depression Scale – Revised, Generalized Anxiety Disorder-7, and the Drug, Alcohol, and Nicotine Scale. We hypothesised that religiosity scores moderate the relationship between existential thinking and mental health, and purpose in life scores mediate the relationship between religiosity and mental health. Religiosity did not moderate the relationships between existential thinking and these outcomes, however, purpose in life scores mediated the relationships of religiosity with depression and anxiety, but not with substance use. Our findings confirm the significance of existential concerns and purpose in life in the religiosity-mental health connection.
