Many religious traditions include a belief in the reality of demonic beings and evil powers. Previous research demonstrates that comforting beliefs, such as believing in an afterlife, can benefit mental health, but less is known about the potentially negative mental health effects of belief in evil supernatural powers. In cross‐sectional analyses, we find that among young adults, believing in demons is one of the strongest (negative) predictors of mental health. More importantly, using three waves of the National Study of Youth and Religion and a cross‐lagged structural equation model, we find that belief in demons can lead to lowered mental health in later waves but low mental health does not lead to greater belief in demons. In fact, when predicting changes in mental health from wave 2 to wave 3 of the study, the negative effect size of belief in demons on mental health is larger in magnitude than all other religion‐related predictors.
Compared to individual‐level research on religion and marijuana use, much less research has been conducted to investigate how the overall religious context of a geographic location may influence marijuana use during adolescence and early adulthood. Using multilevel analyses on two waves of the National Study of Youth and Religion (NSYR) merged with county‐level variables from the U.S. Census and the Religious Congregations and Membership Study (RCMS), this study finds that a county's higher Catholic population share is negatively associated with underage marijuana use frequency even after controlling for a wide range of individual and county‐level variables. Besides being robust, the Catholic contextual effect on marijuana use is also diffusive, influencing both Catholic and non‐Catholic youth who live in the same county. This study highlights the importance of viewing religious influence on substance use as a contextual, cultural force across different kinds of religious moral communities.
Environmental pollution has a significant correlation with people's attitudes towards health policies, even when such policies are not directly concerned with the natural environment. Policy makers may use this opportunity to implement tobacco control measures against the backdrop of China's pollution crisis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
