Grit, basic needs satisfaction, and subjective well-being

In this study, we investigated how grit is related to the satisfaction of the basic needs and subjective well-being. Grit means dedication to long-term goals with enthusiasm, which is closely related to success in objective terms. Thus, we expected that grit would be positively related to satisfying the autonomy and competence needs, which would lead to greater subjective well-being (i.e., higher life satisfaction and lower depression). A survey of young adults (N = 455) revealed that grit is strongly related to both the autonomy and competence needs, and these needs mediated the effect of grit on subjective well-being. Grit did not directly increase life satisfaction but weakly decreased depression. Further, the two basic needs played different roles in enhancing subjective well-being. Autonomy reduced depression, and competence increased life satisfaction.
