Effects of Danmaku and personality on health information consumption on short-form video apps

This study investigated the effects of Danmaku comments, extraversion, and frequency of app usage on user experience and intention to use short-form video apps for health information. Through a 2 (the presence vs. the absence of Danmaku comments) × 2 (extroverted vs. introverted personality) × 2 (low vs. high frequency of use) between-subjects experiment, we collected and analyzed 146 participants’ data (Mean age = 23.0 years, SD = 5.6 years).

When gathering the data, participants firstly completed pre-experiment questionnaire, including demographic information and TIPI-C Scale. Next, the researchers showed participants the interface and how to interact. Participants then were showed with four videos in a random order and their interactions (no interaction, like, comment, collect, share, Danmaku comment) with the interface were recorded. To make sure that participants understood the videos, they were asked about four health tips provided in the videos after watching them. Finally, participants completed the post-experiment questionnaires on trust, acceptance, and intention to use.

本研究考察了弹幕评论（Danmaku comments）、外向性人格特质以及应用使用频率对用户体验与健康信息短视频应用使用意向的影响。本研究采用2（弹幕评论存在vs. 不存在）×2（外向型vs内向型人格）×2（低使用频率vs高使用频率）的被试间实验设计，共收集并分析了146名被试的有效数据（平均年龄23.0岁，标准差（SD）=5.6岁）。
数据收集流程如下：被试首先完成实验前问卷，内容涵盖人口统计学信息与TIPI-C量表。随后，研究者向被试演示应用界面及交互操作方式。接下来，被试将按随机顺序观看四段短视频，研究者同步记录其与界面的各类交互行为（无交互、点赞、评论、收藏、分享、弹幕评论）。为确保被试充分理解视频内容，在观看结束后需回答视频中呈现的四条健康贴士相关问题。最后，被试完成关于信任度、接受度及使用意向的实验后问卷。
