The current study aimed to investigate the mediating role of metacognitions, intolerance of uncertainty and emotion regulation in the relationship between fear of COVID-19 (FC-19) and health anxiety, among families with COVID-19 infected. Participants were 541 individuals from family members of patients with COVID-19 (F = 52.3%, mean age = 41.3 ± 13.2 years). Data were collected with a packet including sociodemographic and risk factors, the Fear of COVID-19 Scale, the Short Health Anxiety Inventory, the Metacognitions Questionnaire 30, the Intolerance of Uncertainty Scale-12 and the Emotion Regulation Questionnaire. Structural equation modelling analyses revealed a full mediation of metacognitions (i.e., positive beliefs about worry, negative beliefs about thoughts concerning uncontrollability and danger, cognitive confidence and beliefs about the need to control thoughts), intolerance of uncertainty and expressive suppression in the relation between FC-19 and health anxiety. Moreover, the strongest indirect links were found between FC-19 and health anxiety through negative beliefs about thoughts concerning uncontrollability and danger and intolerance of uncertainty. These associations were independent of gender and risk status. The final model accounted for 71% of the variance of health anxiety. These findings suggest that particularly metacognitions, intolerance of uncertainty and expressive suppression play a full mediational role in the relation between FC-19 and health anxiety.

感染 COVID-19 的家庭对 COVID-19 的恐惧与健康焦虑的关系：元认知、不确定性不耐受和情绪调节的中介作用

目前的研究旨在调查感染 COVID-19 的家庭中元认知、不确定性不耐受和情绪调节在对 COVID-19 (FC​​-19) 的恐惧与健康焦虑之间的关系中的中介作用。参与者是来自 COVID-19 患者家属的 541 人（F = 52.3%，平均年龄 = 41.3 ± 13.2 岁）。数据是用一个数据包收集的，其中包括社会人口学和风险因素、对 COVID-19 量表的恐惧、短期健康焦虑量表、元认知问卷 30、不确定性不耐受量表 12 和情绪调节问卷。结构方程模型分析揭示了元认知（即，关于担忧的积极信念、关于不可控和危险的消极信念、认知信心和关于需要控制思想的信念）、对不确定性的不容忍和表达抑制在 FC 之间的关系中的完全中介。 -19 和健康焦虑。而且，FC-19 与健康焦虑之间最强烈的间接联系是通过对有关不可控性、危险和不容忍不确定性的想法的负面信念而发现的。这些关联与性别和风险状况无关。最终模型占健康焦虑方差的 71%。这些研究结果表明，特别是元认知、对不确定性的不容忍和表达抑制在 FC-19 与健康焦虑之间的关系中发挥了充分的中介作用。
