Physician wellness (well-being) is recognized for its intrinsic importance and impact on patient care, but it is a construct that lacks conceptual clarity. In this systematic review, published in Academic Psychiatry, authors characterize the conceptualization of physician wellness in the literature by synthesizing definitions and measures used to operationalize the construct. The authors assert that clarity and consensus regarding the conceptual definition of physician wellness is needed to advance the development of valid and reliable physician wellness measures, improve the consistency by which the construct is operationalized, and increase comparability of findings across studies.
