In order to assess patients' ability to search, understand, and benefit from Internet-based information, several screening tools have been developed. One of these tools, which has been widely used, is the eHealth Literacy Scale (eHEALS). The aim of this study was to examine the measurement properties of the Norwegian version of the eHEALS, as it was used in a group of patients undergoing day surgery.
A cross-sectional survey study was conducted among 119 patients scheduled for day surgical treatment in a Norwegian hospital. The questionnaire included the screening tool eHEALS, which contains 8 items for assessing a person's information awareness skills, information seeking skills, and skills to evaluate and act based on the information. Cronbach's alpha coefficients and item-total correlations were assessed for estimating reliability of the eHEALS. Exploratory factor analysis with Oblimin rotation was used for assessing the validity of the scale. Eigenvalue was set to 1.0.
A Cronbach's alpha coefficient of 0.89 for the total scale, values >0.82 for Alpha if Item Deleted, and moderate to high item-total correlations supported the homogeneity and internal consistency of the scale. A two-component solution explained a total of 74.8% of the variance, with the first component explaining 59.53% of the variance in the scale and included the items reflecting information awareness and seeking. The second component explained 15.23% of the variance, including items reflecting the ability to evaluate and act.
The reliability of the Norwegian version of eHEALS, used in a group of patients undergoing day surgery, was good. The internal structure, with two distinct factors, is in line with several previous studies. The eHEALS appears to be an appropriate tool for assessing eHealth literacy among this patient group.
为评估患者搜索、理解基于互联网的信息并从中获益的能力，已开发了多种筛查工具。其中一种被广泛使用的工具是电子健康素养量表（eHEALS）。本研究的目的是检验eHEALS挪威语版本在一组接受日间手术的患者中使用时的测量特性。
对挪威一家医院计划接受日间手术治疗的119名患者进行了横断面调查研究。问卷包括筛查工具eHEALS，它包含8个项目，用于评估一个人的信息意识技能、信息寻求技能以及基于信息进行评估和行动的技能。评估了克朗巴哈α系数和项目与总分的相关性以估计eHEALS的信度。采用具有斜交旋转的探索性因子分析来评估该量表的效度。特征值设定为1.0。
总量表的克朗巴哈α系数为0.89，删除项目后的α值>0.82，且项目与总分的相关性为中度到高度，支持了量表的同质性和内部一致性。一个两成分的解决方案解释了总方差的74.8%，第一个成分解释了量表中方差的59.53%，包括反映信息意识和寻求的项目。第二个成分解释了15.23%的方差，包括反映评估和行动能力的项目。
在一组接受日间手术的患者中使用的eHEALS挪威语版本的信度良好。具有两个不同因子的内部结构与之前的几项研究一致。eHEALS似乎是评估该患者群体电子健康素养的合适工具。
