Although previous investigations had confirmed the significant relationship between socioeconomic status (SES) and well-being, limited work examined bothroles of subjective SES and objective SES on subjective well-being. The present study investigated the association between subjective SES, objective SES, and subjective well-being. Further, few studies examine whether mindset of socioeconomic status might change the magnitude of the relationship between SES and subjective well-being, which will be explored in the current study. Our results showed that both objective SES and subjective SES were positively correlated with subjective well-being. Also, growth mindset of SES was significantly correlated with subjective well-being. Besides, mindset of socioeconomic status is a significant moderator in objective SES- subjective well-being linkage, as well as relationship between subjective SES and subjective well-being. On one hand, in the objective SES dimension, people holding growth mindset reported a stronger association with subjective well-being. On the other hand, people holding fixed mindset of SES showed stronger association in the relationship between subjective SES and subjective well-being. These findings suggested that mindset of SES is beneficial in improving individual subjective well-being and was able to moderate the impact that social status brought to individual subjective well-being.
