Validity and reliability testing of the Indonesian version of the eHealth Literacy Scale during the COVID-19 pandemic

Abstract

Nowadays, it is common for people to look for health care information on the internet. The eHealth Literacy Scale (eHEALS) is commonly used to measure eHealth literacy. As of the publication of this study, the Indonesian version for eHEALS has not been published even though eHealth literacy is necessary, especially in the current COVID-19 pandemic. We aimed to evaluate the validity and reliability of the Indonesian version of eHEALS (I-eHEALS). A total of 100 respondents in East Java were involved in this cross-sectional study. Pearson-product moment correlation method and construct validity were used to validate the results. The reliability was determined based on the Cronbach’s alpha internal consistency measurement and intraclass correlation coefficient (ICC). The Pearson correlation analysis results are significantly higher ( r > 0.254, p < 0.01) compared to the critical value table. Single factors accounting for 57.66% variance in the scales exhibit a unidimensional latent structure. The internal consistency between items is excellent as shown by the Cronbach’s alpha coefficient (0.91). The ICC analysis shows an acceptable result (0.552, p < 0.01). The I-eHEALS is valid and reliable to be used for evaluating the eHealth literacy of the Indonesian population.
