Analysis of Informative Content on Cerebral Palsy Presented in Brazilian-Portuguese YouTube Videos

<b>Aims:</b> To describe the characteristics of the most accessed YouTube videos in Brazilian-Portuguese on cerebral palsy (CP), and to analyze content of informational videos about this topic. <b>Methods:</b> This was a cross-sectional study. Searching on YouTube website was conducted by two independent examiners between November and December 2019, using the keywords “<i>Paralisia Cerebral</i>” sorted by videos’ number of views. Videos that did not present content related to CP or duplicate videos were excluded. The interaction parameters and content characteristics of the included videos were extracted. To access the trustworthiness and quality of informational videos, the modified Discern checklist and the Global Quality Score was used. <b>Results:</b> Following the eligibility criteria 90 videos were included. Fifty-three (53) were classified as experiential videos and 37 as informational videos. Informational videos presented multi-topics about different aspects of CP. This group of videos presented moderate trustworthiness due to the lack of scientific evidence content. Informational videos had good quality and generally good flow. <b>Conclusion:</b> YouTube presented a large number of videos about CP in Brazilian-Portuguese. Informational videos are useful for patients and healthcare providers; however, it is necessary to included information about scientific evidence, as a strategy to facilitate and promote knowledge translation.

**研究目的**：旨在描述巴西葡萄牙语语境下YouTube平台上访问量最高的脑瘫（cerebral palsy, CP）相关视频的特征，并分析该主题下信息类视频的内容。
**研究方法**：本研究为横断面研究。2019年11月至12月期间，由2名独立审查员在YouTube平台开展检索，以关键词“Paralisia Cerebral”进行检索，并按视频播放量排序。排除与脑瘫无关及重复的视频，提取纳入视频的交互参数与内容特征。为评估信息类视频的可信度与质量，本研究采用改良版Discern检查表（modified Discern checklist）及全球质量评分（Global Quality Score）进行分析。
**研究结果**：按照纳入标准，最终纳入90个视频。其中53个被归类为体验类视频，37个为信息类视频。信息类视频涵盖脑瘫多维度相关主题。由于缺乏科学证据内容，该类视频的可信度处于中等水平，但整体质量良好且叙事流畅度佳。
**研究结论**：YouTube平台上存在大量巴西葡萄牙语的脑瘫相关视频。信息类视频可为患者及医疗从业者提供有效参考，但需补充科学证据相关内容，以助力知识传播与转化。
