The Role of Positive Emotion in Mediating the Relationship Between Psychological Distress and Physical Health

Abstract

This study explores the mediating role of positive emotions in the relationship between psychological distress and physical health outcomes. Using a cross-sectional design, we assessed 300 adult participants (50% male, 50% female) from the general population who completed self-report measures of psychological distress (DASS-21), positive emotions (PANAS), and physical health. Mediation analysis revealed that psychological distress negatively affected both positive emotions and physical health. Positive emotions were found to partially mediate the relationship between distress and physical health, with higher positive emotions associated with better physical health outcomes, even in the presence of distress. The indirect effect was significant (β = 0.10, 95% CI = [0.03, 0.17]), suggesting that promoting positive emotional experiences may buffer the physical consequences of psychological distress. Gender moderated this effect, with stronger mediation observed among female participants. These findings highlight the importance of fostering positive emotions as a strategy for improving overall well-being, particularly in individuals experiencing psychological distress.
