ABSTRACT
Purpose: This study aimed to define and clarify the concept of colleague solidarity experienced by nurses during the COVID-19 pandemic. Methods: A hybrid model method was used to investigate the dimensions, attributes, and definitions of the concept. In the theoretical phase, 20 articles selected through literature review by including nursing and related disciplines were analyzed. For the fieldwork phase, in-depth interviews were conducted with nine nurses who took care of infected patients with COVID-19 at Infectious Diseases Specialized Hospital. Results: The dimensions identified were consistently observed in the field phase, however, more attributes were found newly from the fieldwork phase. In the final phase, the concept of colleague solidarity among the nurses was found to have three dimensions with nine attributes. The interaction dimension had four attributes as voluntary support, mutual respect, open communication, and virtuous circle. The motivation dimension had two attributes of sense of communion and calling. Lastly, the relationship dimension had three attributes of unity, mutually equal relationship, and comradeship. Conclusions: This study is meaningful in observing how the concept of colleague solidarity, which is relatively unfamiliar to domestic nurses, appears in the clinical field during a national crisis and analyzing the concept. © 2021 Korean Academy of Nursing Administration
