With the increasing effects of stress caused by the COVID-19 pandemic and occupational stress on the mental health of frontline nurses, it is imperative to further investigate how these stresses affect nurses' mental health and secondary traumatic stress syndrome. This research aimed to investigate the relationship of nurses' occupational stress and concerns about COVID-19 with secondary traumatic stress syndrome, and also to investigate the mediating effect that concerns about the COVID-19 pandemic have on the relationship between nurses' occupational stress and secondary traumatic stress syndrome. A cross-sectional design was adopted. The population of the study was defined as all front-line nurses in Shiraz hospitals, from which 225 nurses of two corona care hospitals were selected using convenience sampling. The degree of secondary traumatic stress, concerns about the COVID-19, and nurses' occupational stress were assessed using Bride's Secondary Traumatic Stress Scale (STSS), an adopted version of Level of Concerns about the COVID-19 questionnaire, and the Nurses' Occupational Stressor Scale (NOSS) among Hospital-based Healthcare Workers. Structural equation modeling (SEM) was used to examine the relationships among variables. Results showed that nurses' occupational stresses presented a direct effect on nurses' level of concern about the COVID-19 pandemic (β = 0.85, P < 0.001), and concern about the COVID-19 pandemic was directly related to front-line nurse's secondary traumatic stress syndrome (β = 0.83, P < 0.001). In addition, nurses' level of concern about the COVID-19 pandemic fully mediated the effects of nurses' occupational stresses on their secondary traumatic stress (β = 0.70, P < 0.001). This indirect effect has explained 68% of the variance in nurses' secondary traumatic stress. These results emphasized the indirect effect of nurses' occupational stresses on secondary traumatic stress syndrome via mediating the level of concern about COVID-19. Therefore, to reduce the secondary traumatic stress of nurses who have dealt directly with COVID-19 patients, it seems necessary to pay serious attention to the sources of their occupational stress, which probably existed even before this pandemic and increased their concerns in pandemic conditions.
随着新冠疫情引发的压力以及职业压力对一线护士心理健康的影响日益增加，进一步研究这些压力如何影响护士的心理健康和继发性创伤应激综合征势在必行。本研究旨在调查护士的职业压力和对新冠疫情的担忧与继发性创伤应激综合征之间的关系，并研究对新冠疫情的担忧在护士职业压力与继发性创伤应激综合征关系中所起的中介作用。本研究采用横断面设计。研究总体定义为设拉子医院的所有一线护士，通过便利抽样从两所新冠护理医院中选取了225名护士。使用布赖德继发性创伤应激量表（STSS）、新冠疫情担忧程度问卷的修订版以及医院医护人员职业压力源量表（NOSS）来评估继发性创伤应激程度、对新冠疫情的担忧以及护士的职业压力。采用结构方程模型（SEM）来检验变量之间的关系。结果表明，护士的职业压力对护士对新冠疫情的担忧程度有直接影响（β = 0.85，P < 0.001），对新冠疫情的担忧与一线护士的继发性创伤应激综合征直接相关（β = 0.83，P < 0.001）。此外，护士对新冠疫情的担忧程度完全中介了护士职业压力对其继发性创伤应激的影响（β = 0.70，P < 0.001）。这种间接效应解释了护士继发性创伤应激变异的68%。这些结果强调了护士职业压力通过介导对新冠疫情的担忧程度对继发性创伤应激综合征产生的间接影响。因此，为了减轻直接接触新冠患者的护士的继发性创伤应激，似乎有必要认真关注其职业压力源，这些压力源可能在疫情之前就已存在，并在疫情期间加剧了他们的担忧。
