This study aimed to develop and validate the eHealth Literacy and Use Scale (eHLUS), a German assessment tool designed to measure health literacy in the context of using medical apps. This scale enhances traditional eHealth literacy tools by focusing on the unique requirements of medical app use, such as integration into everyday life, and self-efficacy.
This study employed a mixed-method design.
The development of the eHLUS involved a thorough literature review, expert interviews, and psychometric evaluation in a real-world environment.
The eHLUS, consisting of 14 items across three dimensions, was designed for a nuanced assessment of eHealth literacy in medical apps. Psychometric evaluation data were gathered from 127 participants at two time points (n = 117; n = 62). The scale demonstrated excellent internal consistency, with a Cronbach's alpha of 0.913 and a McDonald's omega of 0.911. A mean completion time of 2.2 min underscores its practical applicability. Retest reliability was confirmed in 52 matched cases, affirming the scale's stability. Principal component analysis revealed three dimensions: autonomous use and technical access, eHealth engagement, and eHealth literacy.
The findings demonstrate the suitability of eHLUS for assessing individuals' abilities to effectively use medical apps, highlighting its importance in research and healthcare. The evaluation of the scale, along with expert interviews, underscores both its necessity and feasibility. The eHLUS captures eHealth literacy and its associated determinants within the context of medical app use, contributing to the optimization of patient care.
本研究旨在开发并验证电子健康素养与使用量表（eHLUS），这是一种德语评估工具，旨在衡量在使用医疗应用程序背景下的健康素养。该量表通过关注医疗应用程序使用的独特要求，如融入日常生活和自我效能感，对传统电子健康素养工具进行了改进。
本研究采用混合方法设计。
eHLUS的开发涉及全面的文献综述、专家访谈以及在现实环境中的心理测量评估。
eHLUS由三个维度的14个项目组成，旨在对医疗应用程序中的电子健康素养进行细致评估。在两个时间点从127名参与者那里收集了心理测量评估数据（n = 117；n = 62）。该量表显示出出色的内部一致性，克朗巴哈系数为0.913，麦克唐纳欧米伽系数为0.911。平均完成时间为2.2分钟，突出了其实际适用性。在52例匹配病例中证实了重测信度，确认了该量表的稳定性。主成分分析揭示了三个维度：自主使用和技术接入、电子健康参与度以及电子健康素养。
研究结果表明eHLUS适用于评估个体有效使用医疗应用程序的能力，凸显了其在研究和医疗保健中的重要性。对该量表的评估以及专家访谈强调了其必要性和可行性。eHLUS在医疗应用程序使用的背景下捕捉电子健康素养及其相关决定因素，有助于优化患者护理。
