    The study aimed to perform confirmatory factor analysis, internal consistency, gender differential item functioning, and discriminant validity of the Fear of COVID-5 Scale in emerging adult students of a university in Mexico. Confirmatory factor analysis, internal consistency (Cronbach's alpha and McDonald's omega), and gender differential item functioning were estimated (Kendall tau b correlation). The Fear of COVID-5 Scale showed a one-dimension structure (RMSEA = 0.07, CFI = 0.98, TLI = 0.96, and SRMR = 0.02), with high internal consistency (Cronbach's alpha of 0.78 and McDonald's omega of 0.81), non-gender differential item functioning (Kendall tau b between 0.07 and 0.10), and significant discriminant validity (Higher scores for fear of COVID-19 were observed in high clinical anxiety levels). In conclusion, the Fear of COVID-5 Scale presents a clear one-dimension structure similar to a previous study.

    Psychometric Properties of an Instrument to Assess the Fear of COVID-19 in a Sample in Argentina: a Mixed Approach
    (2022-01-14) Scoppetta, Orlando; Cassiani‑Miranda, Carlos Arturo; Arismendy‑Lopez, Yinneth Andrea; Tirado‑Otálvaro, Andrés Felipe; Neurociencias
    The FCV-19S was the frst instrument designed to assess the severity of fear related to COVID-19 and has already been validated in many languages. The objective of this study was to evaluate the homogeneity and construct validity of the 5-item version of the FCV19S, using an online questionnaire in 599 people. The participants’ age ranged from 18 to 65 years. Age, gender, marital status, educational level, employment status, and socioeconomic status were analyzed. In the evaluation process we assessed interitem correlation, item rest-correlation, confrmatory factor analysis: Root Mean Square Error of Approximation, Comparative Fix Index, Tucker-Lewis Index; internal consistency (Cronbach’s alpha, McDonald’s omega), and the Rasch model was assessed for learning more about the psychometric properties of the scale, which allows a detailed knowledge of the strengths and weaknesses of a scale. The FCV-5S has adequate psychometric indicators from the perspective of the Classical Theory of Items. The major limitations were using a self-reported measure and having a convenience sample not necessarily representative of the general population of Argentina.
