Abstract

OBJECTIVE

This cross-sectional validation work evaluated the psychometric features of the COVID-19 Media Literacy Scale (C-19MLs) in Students.

METHODS

The study was conducted on 530 students from a medical university in Hamadan, Iran, who were recruited through a stratified cluster random sampling process in June-July 2020. Intraclass Correlation Coefficient (ICC) and internal consistency were used to assess the reliability. Moreover, CFA (Confirmatory Factor Analyses) and EFA (Exploratory Factor Analyses) were carried out to examine construction validity. CVR (Content Validity Ratio) and CVI (Content Validity Index) were used to examine the content validity.

RESULTS

According to the factor analysis, it was indicated that the C-19MLs included 21 items measuring five dimensions (constructedness of credible Covid-19 media messages, contractedness of fake media coronavirus messages, fake media coronavirus messages, audience, with three questions in each factor; format, represented lifestyles in fake media coronavirus messages with six questions in each factor) for an explanation of 58.4% of the prevalent variance. The average scores for the CVI and CVR were respectively 0.94 and 0.77. According to confirmatory factor analysis, the studied model had an appropriate fitting to the data; the relative chi-square (x2/df) = 2.706 < 3, RMSEA = 0.093 ≤ 0.1; CFI = 0.893 ≥ 0.9; TLI = 0.874 ≥ 0.9; GFI = 0.816 ≥ 0.9; and SRMR = 0.06 ≤ 0.08. Further analyses represented acceptable findings for internal consistency reliability values with 0.86 of Cronbach's alpha.

CONCLUSIONS

The results proved that the C-19MLs is a reliable and valid tool, and it is suitable and acceptable now and can be utilized in forthcoming investigations. This highlights educators and stakeholders to realize the importance of participating individuals in the new media ecology and new 'Infomedia' ecosystems for enabling people in the current digital society.

摘要

目的

本横断面验证工作评估了 COVID-19 媒体素养量表（C-19MLs）在学生中的心理计量学特征。

方法

该研究于 2020 年 6 月至 7 月在伊朗哈马丹的一所医科大学进行，通过分层整群随机抽样过程招募了 530 名学生。使用组内相关系数（ICC）和内部一致性来评估可靠性。此外，还进行了 CFA（验证性因子分析）和 EFA（探索性因子分析）以检验构建效度。使用 CVR（内容效度比）和 CVI（内容效度指数）来检验内容效度。

结果

根据因子分析，C-19MLs 包括 21 个项目，用于测量五个维度（可信的 COVID-19 媒体信息的建构性、虚假媒体冠状病毒信息的紧缩性、虚假媒体冠状病毒信息、受众，每个因素有三个问题；格式，用每个因素的六个问题表示虚假媒体冠状病毒信息中的生活方式），解释了 58.4%的主要方差。CVI 和 CVR 的平均得分分别为 0.94 和 0.77。根据验证性因子分析，所研究的模型与数据具有适当的拟合度；相对卡方（x2/df）=2.706<3，RMSEA=0.093≤0.1；CFI=0.893≥0.9；TLI=0.874≥0.9；GFI=0.816≥0.9；SRMR=0.06≤0.08。进一步的分析表明，内部一致性可靠性值为 0.86，Cronbach 的 alpha 具有可接受的结果。
