Testing reliability and validity of the Vietnamese version of the eHealth literacy scale (eHEALS) among medical students in Vietnam

Background: In the context of COVID-19 pandemic, eHealth Literacy is important and essential for healthcare workers, especially medical students; eHealth Literacy Scale (eHEALS) was developed to measured eHealth lit-eracy of individuals, with higher eHEALS scores indicated greater ehealth literacy.Objectives: The study evaluates the reliability and validity of Vietnamese version of eHEALS and analyzed some factors affecting on eHEALS score among Hanoi Medical University students in Vietnam.Methods: A cross-sectional study design was adopted, and data were elicited from 494 medical students. Exploratory Factor Analysis (EFA); Cronbach's alpha and correlation coefficients; split-half assessment; Poisson regression analysis were applied.Results: The total score of our subjects in the eHEALS was 30.34 +/- 4.57. The results from Bartlett's test, Kaiser-Meyer-Olkin (KMO) test, calculated Cronbach's alpha coefficient and test-retest reliability were high. Poisson regression identified that eHEALS scores of participants was significantly associated with device, ongoing medical condition and trustworthiness of health information source (p < 0.05). Discussion: Our study helps researchers who conduct studies in eHealth develop optimal applied and intervention researches in subjects with medical knowledge. Additional studies need to be required with numerous different groups of people in Vietnam.Conclusion: The Vietnamese version of eHEALS is a reliable and valid measure. Device, medical condition and trustworthiness of health information source are factors affecting on eHEALS score of students in Hanoi Medical University.
