背景:这项研究的目的是评估有关美感异常(MP)的YouTube视频的可靠性,质量,以及质量水平之间的差异。
方法:我们分析了59个与MP相关的视频。我们评估了几个视频特征,包括视图,喜欢,不喜欢,持续时间,和扬声器配置文件。我们使用了视角比率,像比率,视频功率指数(VPI),全球质量量表(GQS),JAMA标准,并修改了DISCERN(mDISCERN)以评估观众的参与度,人气,教育质量,和可靠性。
结果:这些视频共获得4,009,141次观看次数(平均67,951.54次),25.4%的人专注于运动训练,23.7%的人专注于疾病信息。平均得分分别为mDISCERN2.4、GQS2.8和JAMA2.1。医生主导的视频有更高的mDISCERN分数,虽然盟军卫生工作者主导的视频有更多的观点,喜欢,不喜欢,视图比率,和VPI。低劣和高质量的视频在视图上有所不同,喜欢,视图比率,VPI,和持续时间。mDISCERN之间存在正相关,JAMA,和GQS分数,视频持续时间与GQS呈正相关。
结论:讨论疾病的YouTube视频内容会显著影响观众的参与度和受欢迎程度。为了提高YouTube上有价值内容的可用性,缺乏同行评审过程,医疗专业人员必须提供适合其目标受众的高质量教育材料。
BACKGROUND: The purpose of this study was to evaluate YouTube videos on meralgia paresthetica (MP) for reliability, quality, and differences between quality levels.
METHODS: We analyzed 59 videos related to MP. We evaluated several video characteristics, including views, likes, dislikes, duration, and speaker profile. We used view ratio, like ratio, Video Power Index (VPI), Global Quality Scale (GQS), JAMA criteria, and modified DISCERN (mDISCERN) to assess viewer engagement, popularity, educational quality, and reliability.
RESULTS: The videos received a total of 4,009,141 views (average 67,951.54), with 25.4% focused on exercise training and 23.7% focused on disease information. Mean scores were mDISCERN 2.4, GQS 2.8, and JAMA 2.1. Physician-led videos had higher mDISCERN scores, while allied health worker-led videos had more views, likes, dislikes, view ratios, and VPI. Poor and high-quality videos differed in views, likes, view ratio, VPI, and duration. Positive correlations existed among mDISCERN, JAMA, and GQS scores, with video duration positively correlated with GQS.
CONCLUSIONS: The content of YouTube videos discussing diseases significantly influences viewer engagement and popularity. To enhance the availability of valuable content on YouTube, which lacks a peer review process, medical professionals must contribute high-quality educational materials tailored to their target audience.
