Abstract

Background: Cancer patients increasingly use YouTube for nutritional guidance, yet information quality varies substantially. Existing text-based assessment tools fail to capture audiovisual content characteristics. This study aimed to (1) develop a video-specific assessment tool, (2) evaluate German-language YouTube videos on cancer nutrition, and (3) identify quality indicators for laypersons.

Methods: A 20-criteria assessment tool integrating established instruments and video-specific elements was developed. The first 30 YouTube videos on cancer nutrition were systematically evaluated. Spearman correlation and Kruskal-Wallis tests identified associations between video characteristics and quality scores. Interrater reliability was assessed.

Results: Intraclass correlation coefficient indicated good to very good interrater reliability (95% CI: 0.87-0.96). Overall video quality was poor (mean: 38.6/60, SD: 5.3). Videos from hospitals (P = .002) and healthcare organizations (P = .006) scored significantly higher than those from independent persons. Videos with clearly formulated goals (r_s = 0.71, P < .001) and cited references (r_s = 0.43, P = .019) demonstrated stronger evidence-based content. High-quality videos more frequently addressed missing evidence (r_s = 0.51, P = .004). Quality scores inversely correlated with likes (r_s = -0.55, P = .002) and views (r_s = -0.46, P = .01).

Conclusion: YouTube videos on cancer nutrition exhibit substantial quality deficits, even from institutional providers. The validated assessment tool identifies observable quality indicators including clear objectives, scientific citations, transparent discussion of evidence gaps, and institutional authorship. However, no single feature reliably predicts quality. Strengthening digital health literacy and improving evidence-based content production and visibility remain essential priorities.

为YouTube视频提供医疗内容的评估工具的开发：关注营养和癌症。

背景：癌症患者越来越多地使用YouTube进行营养指导，但信息质量差异很大。现有的基于文本的评估工具无法捕捉视听内容的特征。本研究旨在(1)开发视频专用评估工具，(2)评估YouTube上关于癌症营养的德语视频，以及(3)为外行人确定质量指标。方法：综合现有仪器和视频特定元素，开发了一个20项标准的评估工具。前30个关于癌症营养的YouTube视频被系统地评估。Spearman相关和Kruskal-Wallis测试确定了视频特征和质量分数之间的联系。评估了相互间的信度。结果：组内相关系数显示良好至非常好的组间信度（95% CI: 0.87-0.96）。整体视频质量较差（平均值：38.6/60,SD: 5.3）。来自医院（P = 0.002）和医疗机构（P = 0.006）的视频得分明显高于来自独立人士的视频。目标明确的视频(rs = 0.71, P rs = 0.43, P =。019)表现出更强的循证内容。高质量视频更频繁地解决了缺失的证据（rs = 0.51, P = 0.004）。质量得分与喜欢度呈负相关(rs = -0.55, P =。002)和视图（rs = -0.46, P = 0.01）。结论：YouTube上关于癌症营养的视频显示出严重的质量缺陷，即使来自机构提供商。经过验证的评估工具确定了可观察的质量指标，包括明确的目标、科学引用、对证据差距的透明讨论和机构作者。然而，没有单一的特征可以可靠地预测质量。加强数字卫生知识普及和改进基于证据的内容制作和可见度仍然是至关重要的优先事项。

期刊介绍： ICT is the first journal to spearhead and focus on a new and growing movement in cancer treatment. The journal emphasizes scientific understanding of alternative medicine and traditional medicine therapies, and their responsible integration with conventional health care. Integrative care includes therapeutic interventions in diet, lifestyle, exercise, stress care, and nutritional supplements, as well as experimental vaccines, chrono-chemotherapy, and other advanced treatments. Contributors are leading oncologists, researchers, nurses, and health-care professionals.
