Background and objectives

Studies using YouTube data for various diseases are rapidly increasing. This study aimed to investigate the educational quality, reliability and accuracy of the YouTube videos concerning repetitive transcranial magnetic stimulation (rTMS) applications in patients with stroke.

Methods

This is a descriptive study. A video based search on YouTube was performed on April 18th, 2020 by using keyword ‘stroke repetitive transcranial magnetic stimulation’. The videos were queried using the default settings on YouTube and the results were listed according to relevance. Video parameters and sources were recorded. Quality, reliability and accuracy of the videos were determined with Global Quality Score (GQS), Journal of American Medical Association (JAMA) Benchmark Criteria and Modified DISCERN Questionnaire, respectively.

Results

A total of 21 videos were included in the study. The median number of views for videos was 884 (range: 89-28589) and the median duration was 135 seconds. None of the videos had a negative interaction index. The median value was found to be 3 for all three measurements (GQS, JAMA, and DISCERN). Most of the videos were of intermediate quality (47.6%) and had partial sufficient data (61.9%). In the high-quality group, the number of views, dislikes, the duration of the videos, JAMA and DISCERN scores were higher than the low-quality group (p < 0.05). At the same time, viewing rates of the high-quality group were better than the low and the intermediate-quality group (p < 0.05). There was a significant positive correlation between GQS and number of the views, video duration, number of likes, number of dislikes, viewing rate and modified DISCERN questionnaire scores (p < 0.05).

Conclusion

Our results showed that most of the rated videos were of intermediate quality and had partially sufficient data. It has also been found that high-quality videos have higher viewing rates, more dislikes, longer video durations as well as better reliability and accuracy scores. YouTube videos of higher quality and accuracy are needed to increase awareness of rTMS by stroke patients.

YouTube作为中风经颅磁刺激的信息源:质量,可靠性和准确性分析

背景和目标

使用YouTube数据处理各种疾病的研究正在迅速增加。这项研究旨在调查有关中风患者反复经颅磁刺激(rTMS)应用的YouTube视频的教育质量,可靠性和准确性。

方法

这是一项描述性研究。2020年4月18日,使用关键字“中风重复经颅磁刺激”在YouTube上进行了基于视频的搜索。使用YouTube上的默认设置查询了这些视频,并根据相关性列出了搜索结果。记录了视频参数和来源。视频的质量,可靠性和准确性分别由全球质量得分(GQS),美国医学协会杂志(JAMA)基准标准和改进的DISCERN问卷确定。

结果

该研究总共包括21个视频。视频的观看次数中位数为884(范围:89-28589),持续时间中位数为135秒。这些视频中没有一个互动互动指数为负。发现所有三个测量(GQS,JAMA和DISCERN)的中值均为3。大部分视频的质量中等(47.6%),部分数据充足(61.9%)。在高质量组中,观看次数,不喜欢次数,视频时长,JAMA和DISCERN得分均高于低质量组(p <0.05)。同时,高素质人群的观看率要好于低素质和中等质量人群(p<0.05)。GQS与观看次数,视频时长,喜欢次数,不喜欢次数,观看率和修改后的DISCERN问卷评分之间存在显着正相关(p <0.05)。

结论

我们的结果表明,大多数受评级的视频都是中等质量的,并且具有部分足够的数据。还已经发现,高质量视频具有更高的观看率,更多的不喜欢,更长的视频持续时间以及更好的可靠性和准确性得分。需要更高质量和准确性的YouTube视频,以提高中风患者对rTMS的认识。
