Area of Science:

  • Psychology
  • Sociology
  • Public Health

Background:

  • Religiousness is consistently linked to lower rates of substance use.
  • The psychological mechanisms underlying this association, particularly the role of self-control, remain underexplored.

Purpose of the Study:

  • To investigate whether self-control mediates the relationship between religiousness and substance use behaviors.
  • To examine this mediational pathway across various substance use outcomes and diverse adult samples.

Main Methods:

  • A series of seven studies employing daily diary, cross-sectional, and longitudinal designs.
  • Inclusion of behavioral measures of self-control and control for trait mindfulness.
  • Assessment of alcohol and various drug use behaviors in community and cross-cultural adult samples.

Main Results:

  • Daily prayer predicted subsequent lower alcohol use.
  • Religiousness was associated with lower alcohol use, mediated by self-control.
  • This mediational pattern was robust, consistent across different measures, longitudinal designs, and extended to broader drug use.

Conclusions:

  • Self-control significantly mediates the protective association between religiousness and reduced substance use.
  • These findings highlight self-control as a crucial factor explaining why religious individuals tend to exhibit lower substance use.
  • The results offer valuable insights for interventions aimed at substance use prevention.
