How Does Self-Control Promote Health Behaviors? A Multi-Behavior Test of Five Potential Pathways.

This article investigates how trait self-control influences health behaviors by testing five proposed pathways—valuation, prioritization, habituation, translation, and inhibition—using longitudinal data from 663 adults across eight health behaviors. The valuation pathway showed that self-control affects intentions through attitudes, norms, and perceived behavioral control, which in turn predict behavior. The prioritization pathway revealed that higher self-control increases the influence of cognitive attitudes and perceived control on intentions while reducing reliance on habits and injunctive norms. The habituation pathway demonstrated that self-control promotes habit formation, mediating behavior, and the translation pathway indicated that self-control enhances the consistency between intentions and behavior. Finally, the inhibition pathway found that self-control weakens the impact of affective attitudes and habits on behavior, enabling better impulse control. These findings were consistent across both health-protective (approach) and health-risk (avoidance) behaviors and suggest multiple mechanisms by which self-control facilitates health behavior change.
