The aim of the study was to investigate the popularity, content of Invisalign patient testimonials on YouTube, as well as the sentiment of the related comments.
Using the term "Invisalign experience," the top 100 results on YouTube by view count were screened for English spoken patient videos that attracted comments. Video information (time since video upload, sponsorship), engagement metrics (comments, likes, dislikes, subscriptions), and views were collected. Videos were rated for information completeness (ICS), and comments were classified by origin and content. The emotional loading of the comments was measured using automated sentiment analysis.
The 40 reviewed testimonials scored an average ICS of 3.78 (SD 0.97). ICS, time since upload, and video duration did not appear to significantly influence the number of views, subscriptions, likes, dislikes, and comments. There was a statistically significant difference (P = 0.03) between mean positive (2.01, SD 0.95) and negative sentiment scores (- 1.90, SD 1.14). Commenter's status and overall comment on video were significantly associated with positive sentiment scores. There was a significant association between sponsorship, commenter's status, overall comment on video, focus of concern, perceived Invisalign's disadvantages, and increased negative sentiment scores.
Engagement of audience and views of the most popular Invisalign patient testimonials were not significantly influenced by completeness of information, video duration, and lifespan. The sentiment of viewers' comments about Invisalign treatment was significantly more positive and was significantly associated with their status, content, and sponsorship of videos. Orthodontic trends on YouTube need to be cautiously monitored for planning interventions that improve patients' knowledge about orthodontics.
本研究旨在调查 YouTube 上隐适美患者体验视频的受欢迎程度、内容以及相关评论的情绪。
使用“隐适美体验”这一术语，按观看次数筛选出前 100 个 YouTube 结果，以找到吸引评论的英语患者视频。收集视频信息（视频上传时间、赞助）、参与度指标（评论、点赞、不喜欢、订阅）和观看次数。对视频的信息完整性（ICS）进行评分，并根据来源和内容对评论进行分类。使用自动情感分析测量评论的情感负荷。
40 条回顾的体验报告平均 ICS 评分为 3.78（SD 0.97）。ICS、上传时间和视频时长似乎并未显著影响观看次数、订阅量、点赞、不喜欢和评论。平均积极情感得分（2.01，SD 0.95）和平均消极情感得分（-1.90，SD 1.14）之间存在统计学差异（P=0.03）。评论者身份和对视频的总体评价与积极情感得分显著相关。赞助、评论者身份、对视频的总体评价、关注焦点、感知到的隐适美缺点与负面情感得分增加显著相关。
观众的参与度和最受欢迎的隐适美患者体验报告的观看次数与信息完整性、视频时长和寿命无显著相关性。观众对隐适美治疗评论的情绪明显更为积极，且与他们的身份、评论内容和视频赞助显著相关。需要谨慎监测 YouTube 上的正畸趋势，以便规划干预措施，提高患者对正畸的了解。
