[An Evaluation of the Validity and Reliability of the Face Mask Use Scale's Korean Version among Community-Dwelling Adults].

PURPOSE: This study evaluated the validity and reliability of the Korean version of the Face Mask Use Scale (K-FMUS) among community-dwelling adults. METHODS: The participants of the study were community-dwelling adults in Korea using face masks during the COVID-19 pandemic. The English FMUS was translated into Korean using forward and backward translation procedures. The construct validity and reliability of the K-FMUS were evaluated using the exploratory and confirmatory factor analyses and the internal consistency reliability test. RESULTS: The K-FMUS comprised 6 items divided into 2 factors. The variance of the factors was approximately 79.1%, which suggested that the scale indicated the effectiveness of face mask usage. The two factors were labeled as face mask use in society (4 items) and face mask use at home (2 items). Cronbach's α value for the overall scale was .88. CONCLUSION: The K-FMUS is a valid and reliable scale that can be used to measure face mask usage among community-dwelling adults in Korea during the COVID-19 pandemic.
