Stroke has become a leading cause of death and disability worldwide, resulting in a significant loss of healthy life years and imposing a considerable economic burden on patients, their families, and caregivers. However, despite the growing role of online videos as an emerging source of health information, the credibility and quality of stroke prevention education videos, especially those in Chinese, remain unclear.
This study aims to assess the basic characteristics, overall quality, and reliability of Chinese-language online videos related to public health education on stroke prevention.
We systematically searched and screened stroke prevention-related video resources from 4 popular Chinese domestic video platforms (Bilibili, Douyin, Haokan, and Xigua). General information, including upload date, duration, views, likes, comments, and shares, was extracted and recorded. Two validated evaluation tools were used: the modified DISCERN questionnaire to assess content reliability and the Global Quality Scale (GQS) to evaluate overall quality. Finally, Spearman correlation analysis was conducted to examine potential associations between general video metrics and their quality and reliability.
After searching and screening, a total of 313 eligible videos were included for analysis: 68 from Bilibili, 74 from Douyin, 86 from Haokan, and 85 from Xigua. Among these, 113 (36.1%) were created by health care professionals, followed by news agencies (n=95, 30.4%) and general individual users (n=40, 12.8%). The median scores for the modified DISCERN and GQS were 2 and 3, respectively, suggesting that the included stroke prevention-related videos were relatively unreliable and of moderate quality. Most videos focused on primary stroke prevention and commonly recommended adopting a healthy diet; engaging in physical activity; and managing blood pressure, glucose, and lipid levels. Additionally, videos with longer durations and more comments tended to be more reliable and of higher quality. A positive association was also observed between video quality and reliability.
Overall, the quality and reliability of Chinese-language online videos as a source of stroke prevention information remain unsatisfactory and should be approached with caution by viewers. To address this issue, several measures should be implemented, including establishing an online monitoring and correction system, strengthening the video review process through collaboration with health care professionals, and encouraging more selective and cautious sharing of controversial content. These steps are essential to help curb the spread of online misinformation and minimize its ongoing impact.
中风已成为全球死亡和残疾的主要原因，导致健康生命年大量损失，并给患者、其家庭和护理人员带来相当大的经济负担。然而，尽管在线视频作为一种新兴的健康信息来源发挥着越来越重要的作用，但中风预防教育视频的可信度和质量，尤其是中文视频，仍不明确。
本研究旨在评估与中风预防公共卫生教育相关的中文在线视频的基本特征、整体质量和可靠性。
我们系统地从4个国内流行的中文视频平台（哔哩哔哩、抖音、好看视频和西瓜视频）搜索并筛选了与中风预防相关的视频资源。提取并记录了一般信息，包括上传日期、时长、观看次数、点赞数、评论数和分享数。使用了两种经过验证的评估工具：改良的DISCERN问卷来评估内容可靠性，以及全球质量量表（GQS）来评估整体质量。最后，进行Spearman相关性分析，以检验一般视频指标与其质量和可靠性之间的潜在关联。
经过搜索和筛选，共纳入313个符合条件的视频进行分析：哔哩哔哩68个，抖音74个，好看视频86个，西瓜视频85个。其中，113个（36.1%）由医疗保健专业人员创建，其次是新闻机构（95个，30.4%）和普通个人用户（40个，12.8%）。改良的DISCERN和GQS的中位数分数分别为2和3，表明纳入的中风预防相关视频相对不可靠且质量中等。大多数视频侧重于一级中风预防，通常建议采用健康饮食；进行体育活动；以及控制血压、血糖和血脂水平。此外，时长较长且评论较多的视频往往更可靠且质量更高。视频质量和可靠性之间也观察到正相关。
总体而言，作为中风预防信息来源的中文在线视频的质量和可靠性仍然不尽人意，观众应谨慎对待。为解决这一问题，应采取多项措施，包括建立在线监测和纠正系统，通过与医疗保健专业人员合作加强视频审核流程，以及鼓励对有争议的内容进行更有选择性和谨慎的分享。这些措施对于帮助遏制在线错误信息的传播并最小化其持续影响至关重要。
