Here, we integrate two influential psychological theories: social-identity theory and self-determination theory. Whereas social-identity theory considers how social identities impact the self, self-determination theory elucidates the psychological necessity of feeling related, competent, and autonomous. In this article, we outline and provide justification for a unified theoretical framework that considers how perceptions of personal relatedness, competence, and autonomy are influenced by perceptions that one’s social group is related, competent, and autonomous.
