The purpose of this study was to identify the factors of burnout seen among psychiatric nurses, who are known to have a high incidence of burnout, and also to present issues for future burnout research. In order to do that, a scoping review through a wide range of research was used. It was aimed to clarify the fields that had not been researched by pinning out those which researches were currently been conducted. As a result, 25 articles published in 31 years, between 1990 and 2021, were recruited of which 12 studies found an association between burnout and stress, six studies found an association between burnout and emotional labor, and eight studies found an association between burnout and perspectives other than stress and emotional labor (include duplicates). Through the scoping review, it was suggested that psychiatric nurses’ burnout was caused by stress experiences peculiar to psychiatry and the accompanying emotional experiences. In addition, it can be said that for further research improvements on research examining the causal relationship between stress experiences, associated emotional experiences and burnout, qualitative research to complement quantitative research and intervention research to prevent burnout are required.
