Online short videos promoting public breast cancer literacy: a pretest-posttest control group trial on efficiency, attitude, and influencing factors

The status quo of short videos as a health information source of Helicobacter pylori: a cross-sectional study

Background

Health education about Helicobacter pylori (H. pylori) is one of the most effective methods to prevent H. pylori infection and standardize H. pylori eradication treatment. Short videos enable people to absorb and remember information more easily and are an important source of health education. This study aimed to assess the information quality of H. pylori-related videos on Chinese short video-sharing platforms.

Methods

A total of 242 H. pylori-related videos from three Chinese short video-sharing platforms with the most users, TikTok, Bilibili, and Kwai, were retrieved. The Global Quality Score (GQS) and the modified DISCERN tool were used to assess the quality and content of videos, respectively. Additionally, comparative analyzes of videos based on different sources and common H. pylori issues were also conducted.

Results

The median GQS score and DISCERN score was 2 for H. pylori-related videos analyzed in this study. Non-gastroenterologists posted the most H. pylori-related videos (136/242, 56.2%). Videos from gastroenterologists (51/242, 21.0%) had the highest GQS and DISCERN scores, with a median of 3. Few videos had content on family-based H. pylori infection control and management (5.8%), whether all H. pylori-positive patients need to undergo eradication treatment (27.7%), and the adverse effects of H. pylori eradication therapy (16.1%).

Conclusion

Generally, the content and quality of the information in H. pylori-related videos were unsatisfactory, and the quality of the video correlated with the source of the video. Videos from gastroenterologists provided more correct guidance with higher-quality information on the prevention and treatment of H. pylori infection.

Public first aid education model design study based on user experience

Background

Presently, China's first aid penetration rate remains relatively low, leaving ample room for improvement in the existing first aid education model. Given its role as a service for the general public, public first aid education must thoroughly consider the learning needs and experiences of the public when designing the teaching mode.

Methods

Semi-structured interviews were employed to gather detailed insights into participants' experiences in the first aid learning process. Subsequently, NVivo was utilized to analyze the interviews and identify specific design strategies. Additionally, a 7-point scale questionnaire was employed to assess the intervention effects of music familiarity and the simulation of teaching aids on users' willingness and confidence in learning. Building upon the design strategy, a "feedback device + app" approach was proposed. Finally, user satisfaction was evaluated through a scale questionnaire.

Results

The use of familiar music had a significant positive effect on participants' willingness and confidence to learn, while users' fear of teaching aids had no effect on willingness and confidence. The user experience-based first aid education model can better meet the public's learning needs for first aid knowledge and skills.

Conclusion

This study proposes a first aid education model based on user experience design methodology, which optimizes the public's self-learning experience by evoking positive emotions while circumventing negative emotions. The educational model was recognized by users in terms of design concepts and is expected to help increase first aid prevalence in the future.
