Purpose: The study was carried out to determine the psychological impact levels of nurses and midwives due to the COVID-19 outbreak. Methods: The research is planned in a descriptive type. Nurses and midwives working in any health institution in Turkey constituted the population of the research. The questionnaire form of the study was shared on social media tools between 01 and 14 April 2020 and a total of 758 nurses and midwives were included in the study sample. Personal Information Form, State-Trait Anxiety Inventory and Intolerance of Uncertainty Scale were used as data collection tools. Results: Participants who attended the study were 56.9% of nurses and 43.1% of midwives. Approximately half of the nurses and midwives (48.8%) participating in our study contacted the patient with suspected COVID-19, and 29.8% provided care to the patient diagnosed with COVID-19. Nurses and midwives were scored 52.75 ± 9.80 for State Anxiety, 44.87 ± 7.92 for Trait Anxiety Inventory and 35.16 ± 9.42 for Intolerance of Uncertainty Scale. It has been determined that 54.5% of nurses and midwives have been making their lives worse since the outbreak started, 62.4% had difficulties in dealing with the uncertain situation in the outbreak, 42.6% wanted psychological support and 11.8% had alienated from their profession. It was determined that there was a difference between scale scores and difficulties in work, family and private life due to COVID-19. Conclusion: As a result, it is seen that the midwives and nurses in our country have high psychological effects due to the COVID-19 outbreak.
