Little is known regarding the accuracy, quality, and viewer engagement of video-based online education.
To assess the accuracy, quality, viewer engagement, and viewer experience of rosacea videos on social media.
Reviewers searched "rosacea" and examined videos on YouTube in September 2018. Videos were categorized by source: 1) Healthcare sources: university/professional organizations, industry, and individuals that were healthcare professionals, and 2) Non-healthcare sources: lay media and individuals that were not healthcare professionals. Video accuracy was measured using the Dy et al. Accuracy Scale (DAS) and Accuracy in Digital-health Instrument (ANDI). Video quality was measured using the Global Quality Scale (GQS). Viewer engagement was measured by the engagement ratio (total likes+dislikes+comments/total views).
Of the videos analyzed, 71.7% of videos were from non-healthcare sources. Videos produced by healthcare sources (28.3%) were significantly more accurate than those produced by non-healthcare sources, as measured by ANDI (3.57±0.83 versus 2.54±1.07, P=0.001). Videos created by non-healthcare sources received significantly greater engagement than those by healthcare professionals (viewer engagement ratio 0.031±0.044 versus 0.014±0.013, P=0.0159).
Rosacea videos on social medi produced by non-healthcare sources were less accurate and of lower quality but received greater viewer engagement than those produced by healthcare sources.
关于基于视频的在线教育的准确性、质量和观众参与度知之甚少。
评估社交媒体上酒渣鼻视频的准确性、质量、观众参与度和观众体验。
审查员于 2018 年 9 月在 YouTube 上搜索“酒渣鼻”并检查了视频。根据来源对视频进行分类:1)医疗保健来源:大学/专业组织、行业和医疗保健专业人员的个人,以及 2)非医疗保健来源:非医疗保健专业人员的媒体和个人。使用 Dy 等人的准确性量表(DAS)和数字健康仪器准确性量表(ANDI)测量视频的准确性。使用全球质量量表(GQS)测量视频质量。通过参与率(总点赞+差评+评论/总观看次数)来衡量观众的参与度。
在所分析的视频中,71.7%的视频来自非医疗保健来源。医疗保健来源(28.3%)制作的视频在准确性方面明显高于非医疗保健来源,这是由 ANDI 测量的(3.57±0.83 对 2.54±1.07,P=0.001)。非医疗保健来源制作的视频的参与度明显高于医疗保健专业人员(观众参与度比率 0.031±0.044 对 0.014±0.013,P=0.0159)。
与医疗保健来源制作的视频相比,社交媒体上由非医疗保健来源制作的酒渣鼻视频准确性较低,质量较差,但获得了更大的观众参与度。
