To examine the psychometric properties of the Norwegian version of the Fear of COVID-19 Scale (FCV-19S), randomly selected individuals from a larger registry study were invited. We assessed the reliability and validity of the instrument in a sample of 1089 adults in Norway (response rate 73%). Internal consistency measured by Cronbach’s alpha (0.88) was acceptable. Omega alphaHierarchical (ωt = 0.69) was lower indicating that the general factor is less reliable, explaining 69% of the total variance. Confirmatory factor analysis indicated that the FCV-19S is not strictly unidimensional. Exploratory graph analysis and confirmatory factor analysis supported a two-factor model (cognitive and somatic fear), which were highly correlated (r = 0.84). The Norwegian version of the FCV-19S showed an underlying two-factor structure. However, the high correlation means the two latent factors (cognitive and somatic fear) act as indicators for a second-order general factor and support use of the FCV-19S sum score. The FCV-19S appears to be a valid instrument to assess fear of COVID-19 with good psychometric properties.

为了检验挪威版 COVID-19 恐惧量表 (FCV-19S) 的心理测量特性，我们邀请了从一项更大的注册研究中随机选择的个体。我们评估了该工具在挪威 1089 名成年人样本中的可靠性和有效性（响应率为 73%）。由 Cronbach 的 alpha (0.88) 衡量的内部一致性是可以接受的。Omega alphaHierarchical ( ωt  = 0.69) 较低，表明一般因素不太可靠，解释了总方差的 69%。验证性因素分析表明 FCV-19S 不是严格一维的。探索性图表分析和验证性因素分析支持高度相关的双因素模型（认知和躯体恐惧）（r = 0.84）。挪威版的 FCV-19S 显示出潜在的双因素结构。然而，高度相关意味着两个潜在因素（认知和躯体恐惧）充当二阶一般因素的指标，并支持使用 FCV-19S 总分。FCV-19S 似乎是评估对具有良好心理测量特性的 COVID-19 恐惧的有效工具。
