ABSTRACT
In recent years, there has been an exponential increase in studies demonstrating the positive effects of the religiosity/spirituality (R/S) approach on patients' physical and mental health. In mental health units, patients want professionals to be sensitive to their spiritual and/or religious needs, which is a fundamental aspect of a holistic approach to patients. Qualitative research with an exploratory and descriptive design with an ethnographic-phenomenological approach through in-depth interviews with sixteen professionals from Spanish mental health units. There is no consensus on the definition of spirituality; however, all of them believe that R/S has a positive influence on the health of patients in coping with illness. They believe that their own R/S may interfere with the professional-patient relationship and their attention to spiritual needs. Few professionals address these needs, citing limitations such as lack of time and lack of specific training in spiritual care. More research is needed on the spiritual care of mental health professionals to define the framework, professional training, and associated challenges in the spiritual care of patients.
