Spinal cord injury (SCI) severely affects patients' quality of life. With the rise of short video platforms, they have become important sources of health information, yet few studies have assessed the quality of SCI-related content on these platforms.
This study aimed to analyze the content and quality of SCI-related videos on three major short video platforms.
This study collected SCI-related short videos published between 28 March and 10 April 2025 on three platforms: BiliBili, Kwai, and TikTok. After strict screening (removing advertisements, duplicates, and irrelevant content), 251 valid samples were finally included. To minimize the influence of platform recommendation algorithms, the study used newly registered accounts to conduct standardized searches with "spinal cord injury" as the uniform search term. Video quality was assessed using four methods: Journal of the American Medical Association (JAMA), global quality scale (GQS), modified DISCERN, and patient education materials assessment tool. Two staff members (Z-SH and Z-GF) independently scored all videos. When their ratings differed by more than 15%, an expert (TY) made the final decision.
A total of 251 SCI-related videos were analyzed across BiliBili ( = 68), Kwai ( = 91), and TikTok ( = 92), revealing marked differences in content characteristics and quality. BiliBili featured the longest videos (median: 300 s) and the highest collection rate. It also achieved the highest JAMA (2.10 ± 0.85) and GQS (3.18 ± 0.91) scores. Kwai videos were the shortest (median: 15 s) but generated the most user interaction (likes, comments, and shares). However, it consistently scored lowest across all quality metrics (e.g. JAMA = 1.28 ± 0.42; GQS = 2.00 ± 0.83), with limited understandability (38 ± 24) and actionability (22 ± 24). TikTok content, primarily created by professionals, showed the highest modified DISCERN score (2.80 ± 0.78) and moderate practical value (understandability: 71 ± 21; actionability: 41 ± 29), though user engagement was relatively low. Quality indicators (JAMA, GQS, and DISCERN) were moderately correlated with follower count but weakly or negatively correlated with user engagement. Finally, understandability and actionability showed a moderate correlation ( = 0.49).
This cross-platform comparative study reveals significant disparities in content quality among SCI-related videos on three leading short video platforms. Despite diverse video formats, the overall quality and reliability remain suboptimal.
脊髓损伤（SCI）严重影响患者的生活质量。随着短视频平台的兴起，它们已成为健康信息的重要来源，但很少有研究评估这些平台上与脊髓损伤相关内容的质量。
本研究旨在分析三个主要短视频平台上与脊髓损伤相关视频的内容和质量。
本研究收集了2025年3月28日至4月10日在哔哩哔哩、快手和抖音三个平台上发布的与脊髓损伤相关的短视频。经过严格筛选（去除广告、重复内容和无关内容），最终纳入251个有效样本。为尽量减少平台推荐算法的影响，本研究使用新注册账号以“脊髓损伤”作为统一搜索词进行标准化搜索。使用四种方法评估视频质量：《美国医学会杂志》（JAMA）、全球质量量表（GQS）、改良的DISCERN和患者教育材料评估工具。两名工作人员（Z-SH和Z-GF）对所有视频进行独立评分。当他们的评分差异超过15%时，由一位专家（TY）做出最终决定。
共分析了哔哩哔哩（n = 68）、快手（n = 91）和抖音（n = 92）上的251个与脊髓损伤相关的视频，发现内容特征和质量存在显著差异。哔哩哔哩上的视频最长（中位数：300秒），收藏率最高。它在JAMA（2.10 ± 0.85）和GQS（3.18 ± 0.91）评分中也最高。快手视频最短（中位数：15秒），但产生的用户互动最多（点赞、评论和分享）。然而，它在所有质量指标上的得分始终最低（例如，JAMA = 1.28 ± 0.42；GQS = 2.00 ± 0.83），可理解性（38 ± 24）和可操作性（22 ± 24）有限。抖音内容主要由专业人士创作，显示出最高的改良DISCERN评分（2.80 ± 0.78）和中等的实用价值（可理解性：71 ± 21；可操作性：41 ± 29），尽管用户参与度相对较低。质量指标（JAMA、GQS和DISCERN）与关注者数量呈中度相关，但与用户参与度呈弱相关或负相关。最后，可理解性和可操作性显示出中度相关性（r = 0.49）。
这项跨平台比较研究揭示了三个领先短视频平台上与脊髓损伤相关视频在内容质量上存在显著差异。尽管视频格式多样，但整体质量和可靠性仍不理想。
