| Summary: | Objectives: Many individuals around the world are suffering from psychological distress due to the COVID-19 outbreak. The aim of this study is to explore the validity and reliability of the English version of Stress and Anxiety to Viral Epidemics-6 (SAVE-6), which measures the anxiety response of the general population to the viral epidemic.Methods: A cross-sectional web-based study with self-reporting measures was conducted. A total of 314 United States residents were recruited via online platform in exchange for payment. The participants were asked to an anonymous questionnaire, collecting information on demographics, psychiatric history, SAVE-6, Patient Health Questionnaire-4 (PHQ-4), and the Coronavirus Anxiety Scale.Results: The result from confirmatory factor analysis (CFA) demonstrated that a single-factor model [χ(9)2 = 11.53, p = 0.24] yielded excellent fit for all of indices [χ2/df ratio = 1.28; CFI = 1.00; TLI = 1.00; SRMR = 0.02; RMSEA = 0.03 (0.00, 0.07; 90% CI)] and yielded strong internal consistency reliability (Cronbach's α = 0.88). The results from multigroup CFAs showed that there were no gender differences [Δχ(6)2 = 3.20, p = 0.78, ns] and no race differences [Δχ(6)2=3.60, p = 0.73, ns] between the models, along with excellent model fits.Conclusions: The results of this study support the reliability and validity of SAVE-6 with strong psychometric properties for the English version of the U.S. population.
