Abstract

Gratitude is widely recognized as a protective factor against psychopathology, yet cross-cultural mechanisms linking it to depressive symptoms remain underexplored. This study employs structural equation modeling (SEM) to examine self-esteem and social anxiety as mediators in the relationship between dispositional gratitude and depression among middle-aged adults from the United States (U.S., N = 1,255) and Japan (N = 1,027). Results reveal a dual-process model: a universal intrapersonal pathway and a culturally contingent interpersonal pathway. Across both cultures, higher gratitude was consistently associated with enhanced self-esteem, which in turn predicted lower depressive symptoms. However, social anxiety exhibited significant cultural differences: while gratitude predicted lower social anxiety in the U.S. sample, this effect was nonsignificant in the Japanese sample. This divergence is attributed to the “mixed emotional states” characteristic of collectivist contexts, where gratitude is often intertwined with indebtedness (on-gi) and the fear of imposing a burden (meiwaku). These psychological costs may sustain interpersonal vigilance, neutralizing the anxiety-reducing effects commonly observed in Western contexts. The findings suggest that although gratitude confers robust psychological benefits, the underlying mechanisms are shaped by cultural affordances. Consequently, gratitude-based interventions should be culturally tailored to account for the social obligations and reciprocity pressures inherent in interdependent societies.
