Self-care for health care professionals is essential in order to optimize the care they provide and to prevent serious consequences for their health. This scoping review aimed to identify (a) the concepts used in the literature to describe self-care; (b) interventions that influence self-care. The scoping review was conducted according to the criteria and methodology by Arksey and O’Malley, from November 2020 to January 2021, by consulting the following databases: Pubmed, CINAHL, Scopus, PsycInfo, Cochrane Library, Joanna Briggs Library. Various keywords and MesH terms were used for the search, including self-care, nurses, midwives, nursing, midwifery, self-compassion, and self-awareness. Eighteen studies were included. The concept of self-care is related to three constructs: (a) Mindfulness; (b) Compassion; and (c) Resilience. In the literature, self-care interventions can be distinguished as (a) mindfulness-based; (b) educational; (c) multimodal approach; and (d) mind-body interventions. In recent years, the concept of self-care is a topic of great interest in the literature; dealing with self-care from both a theoretical and a practical—personal and professional—perspective has become more important in order to promote practitioners’ well-being. This scoping review helps to clarify the terms related to self-care and looks at tested interventions to improve the well-being of caregivers.
