Social media have become mainstream online tools that allow individuals to connect and share information. Such platforms also influence people's health behavior in the way they communicate about personal health, treatment, or physicians. Individuals' ability to find and apply online health information on specific health problems can be measured using a valid and reliable instrument, the eHealth Literacy Scale (eHEALS). The objective of this study was to evaluate the psychometric aspects of the Polish version of this instrument (eHEALS-Pl) among social media users, which has not been explored so far. We examined the translated version of the eHEALS in a representative sample of Polish social media users (n = 1527). CAWI (computer-assisted web interviews) was a method to collect data. The reliability of the eHEALS-Pl was measured by calculating the Cronbach alpha coefficients and analyzing the principal components. Exploratory factor analysis and hypothesis testing was used to assess the construct validity of the instrument. The internal consistency of the eHEALS-Pl was sufficient: Cronbach alpha = 0.84. The item-to-total correlations ranged from = 0.514 to 0.666. EFA revealed a single structure explaining 47.42% of the variance, with high factor loadings of the item ranging from 0.623 to 0.769. Hypothesis testing also supported the validity of eHEALS-Pl. The eHEALS-Pl evaluation supported by social media users reviled its equivalence to the original instrument developed by Norman and Skinner in 2006 and it can be used to measure e-health literacy. Since there is no prior validation of the eHEALS among social media users, these findings may indicate important directions in evaluating digital skills, especially in relation to the current challenges related to the COVID-19 pandemic.
社交媒体已经成为主流的在线工具，允许个人进行连接和信息共享。这些平台还通过个人交流有关个人健康、治疗或医生的信息来影响人们的健康行为。个体在特定健康问题上查找和应用在线健康信息的能力可以通过使用有效和可靠的工具来衡量，即电子健康素养量表（eHEALS）。本研究的目的是评估该工具的波兰语版本（eHEALS-Pl）在社交媒体用户中的心理计量学特性，迄今为止尚未对此进行探讨。我们在具有代表性的波兰社交媒体用户样本（n=1527）中检验了 eHEALS 的翻译版本。CAWI（计算机辅助网络访谈）是收集数据的一种方法。通过计算 Cronbach alpha 系数和分析主要成分来衡量 eHEALS-Pl 的可靠性。使用探索性因素分析和假设检验来评估该工具的结构有效性。eHEALS-Pl 的内部一致性是足够的：Cronbach alpha=0.84。项目与总分的相关性范围为=0.514 至 0.666。EFA 揭示了一个单一的结构，解释了 47.42%的方差，项目的因子负荷高，范围从 0.623 到 0.769。假设检验也支持 eHEALS-Pl 的有效性。得到社交媒体用户支持的 eHEALS-Pl 评估表明其与 Norman 和 Skinner 于 2006 年开发的原始工具具有等效性，可以用于衡量电子健康素养。由于之前在社交媒体用户中没有对 eHEALS 进行验证，因此这些发现可能为评估数字技能，特别是与当前与 COVID-19 大流行相关的挑战相关的数字技能，指明了重要的方向。
