More Than Friends and Family? Estimating the Direct and Indirect Effects of Religiosity on Substance Use in Emerging Adulthood

Religiosity tends to negatively influence substance use among emerging adults because religious communities can serve as pro-social reference groups and provide alternative resources for coping with stress and negative life events. The relationship may also be mediated, however, by differences in family attachments and drug- and alcohol-using peer associations. With data from a nationally representative panel study, I implemented longitudinal structural equation modeling to simultaneously assess both direct and indirect effects of religiosity on substance use. While a substantive portion of its effect is mediated by substance-using peers, it is mostly direct, and increasingly so as individuals transition from late adolescence to emerging adulthood. Furthermore, religion appears to be a particularly effective social institution, as religiosity decreases contemporary substance use but is not itself affected by prior substance use. Religiosity may thus be beneficial with regard to certain short- and long-term health outcomes related to substance use during emerging adulthood.
