BACKGROUND IN: the early days of December 2022, the Chinese government ended its restrictive quarantine measures (e.g. nationwide lockdown) against COVID-19, which started in December 2019. Three years of prolonged exposure to the COVID-19 pandemic and restrictive quarantine policy had a notable impact on the mental health of frontline nurses. Traumatic events can have negative effects on people as well as positive ones, such as post-traumatic growth (PTG). Studies have revealed that frontline nurses' self-perceived quality of life had not changed significantly when the pandemic's effects lessened. The Chinese model of fighting the pandemic provided a valuable opportunity for studying the effects of prolonged exposure traumatic events on PTG in individuals.
This cross-sectional study attempted to investigate PTG and its relationship with social support and resilience among frontline nurses during COVID-19 pandemic.
A sample of 378 frontline nurses from tertiary hospitals in China participated in this study. The study took place two weeks after the government announced the end of the quarantine policy in December 2022 in China. Participants' PTG, resilience and social support were assessed using the Post-traumatic Growth Inventory, Social Support Rate Scale and 14-Item Resilience Scale, respectively. PROCESS Procedure Model 4 was employed to examine the mediating role of resilience between social support and PTG.
The results of mediating effect analysis showed that social support could significantly predict resilience (a = 0.752, SE = 0.079, P < 0.001). Social support could significantly predict PTG (c' = 0.366, SE = 0.103, P < 0.001), and resilience could also significantly predict PTG (b = 0.226, SE = 0.060, P < 0.001). Bootstrap test identified a significant mediating effect of resilience between social support and PTG (ab = 0.170, BootSE = 0.077, 95% CI [0.031, 0.330]). The mediating effect contributed 31.72% of the total effect ([a×b]/c=[0.752 × 0.226]/0.536 = 0.3172), indicating a partial mediating role of resilience between social support and PTG.
Resilience partially mediated the relationship between social support and PTG among frontline nurses during COVID-19 pandemic. Improving social support and resilience might be effective intervention strategies for promoting PTG among frontline nurses during traumatic events.
背景：2022年12月初，中国政府结束了自2019年12月开始实施的针对新冠疫情的限制性隔离措施（如全国范围封锁）。长达三年暴露于新冠疫情及限制性隔离政策对一线护士的心理健康产生了显著影响。创伤性事件对人可能有负面影响，也有正面影响，如创伤后成长（PTG）。研究表明，当疫情影响减弱时，一线护士自我感知的生活质量并无显著变化。中国抗击疫情的模式为研究长期暴露于创伤性事件对个体创伤后成长的影响提供了宝贵机会。
本横断面研究旨在调查新冠疫情期间一线护士的创伤后成长及其与社会支持和心理韧性的关系。
来自中国三级医院的378名一线护士参与了本研究。研究于2022年12月中国政府宣布结束隔离政策两周后进行。分别使用创伤后成长量表、社会支持评定量表和14项心理韧性量表对参与者的创伤后成长、心理韧性和社会支持进行评估。采用PROCESS程序模型4检验心理韧性在社会支持和创伤后成长之间的中介作用。
中介效应分析结果显示，社会支持能显著预测心理韧性（a = 0.752，SE = 0.079，P < 0.001）。社会支持能显著预测创伤后成长（c' = 0.366，SE = 0.103，P < 0.001），心理韧性也能显著预测创伤后成长（b = 0.226，SE = 0.060，P < 0.001）。Bootstrap检验确定心理韧性在社会支持和创伤后成长之间有显著中介效应（ab = 0.170，BootSE = 0.077，95% CI [0.031, 0.330]）。中介效应占总效应的31.72%（[a×b]/c = [0.752 × 0.226]/0.536 = 0.3172），表明心理韧性在社会支持和创伤后成长之间起部分中介作用。
在新冠疫情期间，心理韧性在一线护士的社会支持和创伤后成长之间起部分中介作用。改善社会支持和心理韧性可能是在创伤性事件期间促进一线护士创伤后成长的有效干预策略。
