Background: The seven-item Fear of COVID-19 Scale (FCV-19S) assesses severity of fear of COVID-19 (novel coronavirus). The present study translated the scale into Tamil and tested its psychometric properties so that the scale can be used in Tamil-speaking populations. Methods: The FCV-19S was translated into Tamil following a forward-backward translation procedure. Using an online-based survey, 95 participants completed the Tamil version of the FCV-19S alongside questions about demographic information. Psychometric properties were examined using Partial-Credit Rasch analysis, which was suitable for analyzing a questionnaire of this length with the present sample size. Results: The data fit for the Rasch model was confirmed without the need for any adjustments. Item means were comparable to those reported in other studies, with some evidence of clustering of items, although not sufficient to challenge the unidimensionality of the scale. Reliability was very high (α= 0.93), and there was no evidence of differential item functioning by age, sex, or education.Conclusion: The Tamil version of the FCV-19S has a unidimensional structure with robust psychometric properties. It can thus be used in research assessing the psychological impact of COVID-19 among Tamil-speaking populations. Further studies with larger samples are required to provide population reference values.
