Abstract: Researchers have long theorized about the function of self‐esteem. Theories such as sociometer, terror management, and self‐determination have each received substantial empirical support, but all purport a different function of self‐esteem. Despite each theory's persuasiveness, they are sometimes at odds, and there remains no clear consensus regarding the function of self‐esteem. In the present paper, we propose the notion that self‐esteem monitors the meeting of multiple fundamental psychological needs, a theory we call the Need‐Satisfaction Framework of self‐esteem. We outline existing empirical support for our theory in the context of three well‐documented fundamental needs: belonging, self‐determination (i.e.,autonomy and competence), and meaning. Across all three needs, we review converging evidence supporting two hypotheses for self‐esteem's need‐monitoring function: (1) threats to needs lower self‐esteem and (2) high self‐esteem buffers defensive responses to need threats. We expand on established theoretical and empirical work in the domain of self‐esteem and also discuss testable future hypotheses.
