ABSTRACT Through an interdisciplinary literature review, this propositional paper explores the emergence and unfolding of professionals’ moral identity conflicts involving important but contrasting values. Building on the exemplary case of physicians’ professional-religious dilemmas in End-of-Life circumstances, we develop a multilevel model of professional-personal identity conflict dynamics in ethically-charged situations in which we integrate individual-level mechanisms with organizational-level boundary conditions, namely peer social support and ethical climate, in relation to psychological well-being. Our conceptual model contributes to the ethics, identity and human (...) behavior literature by advancing suggestions of how professionals may prevent or/and resolve moral conflicts concerning also other identities and contexts.
