We linked self-determination theory and prosociality, and explored the mediating role of three dimensions of basic psychological needs satisfaction, namely, competence, autonomy, and relatedness, in the relationship between prosocial tendencies and subjective well-being. We explored these relationships using a cross-sectional research design with 1,106 Chinese adults. Results show that the public prosocial tendencies of men (vs. women) were higher, and competence, autonomy, and relatedness mediated the positive relationship between prosocial tendencies and subjective well-being. The indirect effect of relatedness was stronger than those of competence and autonomy, demonstrating the importance of relatedness in a collectivistic society like China. Our findings deepen understanding of the underlying mechanisms between prosociality and subjective well-being as mediated by basic psychological needs satisfaction, and may encourage people to engage in prosocial behavior.
