The rise of the internet and social media has led to increased interest among diabetes patients in using technology for information gathering and disease management. However, adequate eHealth literacy is crucial for protecting patients from unreliable diabetes-related information online.
To examine the psychometric characteristics and explore the preliminary validity of the Persian version of the Condition-specific eHealth Literacy Scale for Diabetes (Persian CeHLS-D) to assess eHealth literacy in the context of diabetes care.
After adapting, translating, examining content validity, and pilot testing the questionnaire, it was administered to 300 patients with type 2 diabetes mellitus (T2DM). Construct validity was assessed through confirmatory factor analysis, convergent and known-groups validity. The internal consistency (Cronbach's alpha), composite reliability and maximum reliability, and test-retest correlation were assessed.
Factor analysis supported the hypothesized two-factor model with 10 items, and the standardized factor loadings ranged from 0.44 to 0.86 (P-values < 0.001). Cronbach's alpha and test-retest correlation were good for each factor. Convergent validity was confirmed by significant correlations of Persian CeHLS-D with diabetes health literacy, perceived usefulness and importance of using the internet for health information, internet anxiety, and perceived physical and mental health. Know-groups validity determined using groups with different internet-use frequencies, and different attitudes towards providing online healthcare services, were satisfied.
This study demonstrated the Persian CeHLS-D as a reliable and valid measure of eHealth literacy among patients with T2DM in Iran. Its satisfactory psychometric properties support its use in research and clinical settings to assess eHealth literacy and inform interventions.
互联网和社交媒体的兴起，使得糖尿病患者对利用技术获取信息和管理疾病的兴趣大增。然而，足够的电子健康素养对于保护患者免受网络上不可靠的糖尿病相关信息至关重要。
旨在检验条件特定电子健康素养量表-糖尿病（Persian CeHLS-D）的心理测量学特征，并探讨其在糖尿病护理背景下评估电子健康素养的初步有效性。
对问卷进行适应性改编、翻译、内容效度检验和预试验后，对 300 例 2 型糖尿病患者进行调查。采用验证性因子分析评估结构效度，同时评估聚合效度和已知组有效性。评估内部一致性（Cronbach's alpha）、综合可靠性和最大可靠性以及测试-重测相关性。
因子分析支持具有 10 个项目的假设两因素模型，标准化因子负荷范围为 0.44 至 0.86（P 值均<0.001）。每个因子的 Cronbach's alpha 和测试-重测相关性均良好。聚合效度通过 Persian CeHLS-D 与糖尿病健康素养、感知互联网在获取健康信息方面的有用性和重要性、互联网焦虑以及感知身心健康的显著相关性得到证实。采用不同互联网使用频率和对提供在线医疗服务的不同态度的分组进行了知组有效性验证，结果均令人满意。
本研究表明，在伊朗 2 型糖尿病患者中，Persian CeHLS-D 是一种可靠且有效的电子健康素养测量工具。其满意的心理测量学特性支持其在研究和临床环境中用于评估电子健康素养并为干预措施提供信息。
