Media health literacy emerges as a response to the vast array of informational disorders prevalent in media communications. Given the absence of a measurement tool for this type of literacy in Spanish-speaking communities, the aim of the present study is to conduct a cross-cultural adaptation of the Media Health Literacy (MeHLit) questionnaire into Spanish and to analyze its psychometric properties in a sample of nursing students.
The Spanish version of the MeHLit questionnaire (MeHLit-SV) was obtained through a process involving translation, back-translation, evaluation of the proposed items by a group of 22 experts, and a pilot study with 80 Spanish nursing students. Content validity was assessed using each item's content validity index (CVI) and Aiken's V (VdA), while internal consistency was evaluated through Cronbach's Alpha.
Following the translation and adaptation process, the final version of the MeHLit-SV comprised 21 items organized into five dimensions. The CVI values exceeded 0.82 for all items, and the overall content validity index (S-CVI) was 0.9. Furthermore, the results of Aiken's V surpassed the threshold considered acceptable (0.70). After piloting, the questionnaire demonstrated high internal consistency with a Cronbach's alpha value of 0.936.
The findings of this research support the reliability and validity of the MeHLit-SV for use among nursing students to measure their level of media health literacy. This questionnaire, with satisfactory psychometric properties and ease of administration, is an useful tool for assessing whether individuals possess the necessary skills to accurately analyze health information they encounter on a daily basis.
媒体健康素养是应对媒体传播中普遍存在的大量信息障碍而出现的一种素养。鉴于西班牙语社区缺乏这种素养的测量工具，本研究旨在对媒体健康素养（MeHLit）问卷进行西班牙语的跨文化适应性改编，并在一组护理专业学生中分析其心理测量特性。
通过翻译、回译、由 22 名专家评估提出的项目以及对 80 名西班牙语护理专业学生进行的预试验等过程，获得了 MeHLit-SV 版的西班牙语问卷。使用每个项目的内容有效性指数（CVI）和 Aiken 的 V（VdA）评估内容有效性，而内部一致性则通过 Cronbach's Alpha 进行评估。
经过翻译和改编过程，MeHLit-SV 的最终版本包括 21 个项目，分为五个维度。所有项目的 CVI 值均超过 0.82，总体内容有效性指数（S-CVI）为 0.9。此外，Aiken 的 V 值超过了被认为可接受的阈值（0.70）。经过试验后，问卷表现出较高的内部一致性，Cronbach's alpha 值为 0.936。
这项研究的结果支持 MeHLit-SV 在护理专业学生中测量其媒体健康素养水平的可靠性和有效性。该问卷具有令人满意的心理测量特性和易于管理的特点，是评估个体是否具备准确分析他们日常遇到的健康信息所需技能的有用工具。
