youtube as a source of patient information for stroke a content quality and an Audience Engagement analysis
Journal of Stroke & Cerebrovascular Diseases, 2020Co-Authors: Tomasz Szmuda, Ahmed Alkhater, Mohammed Albrahim, Eyad Alquraya, Shan Ali, Rakan Al Dunquwah, Pawel SloniewskiAbstract:Abstract Background Stroke is the second leading cause of death worldwide following ischemic heart disease, and the fifth in the United States. The video-sharing database, YouTube, is the second most popular visited website with more than 2 billion users, thus it's increasingly being used as a medium for delivering health information. Aim We aimed to evaluate the quality, reliability and Audience Engagement of stroke-related YouTube videos. Methods In October 2019 we conducted a search on YouTube using 5 keywords: stroke, brain attack, hemorrhagic stroke, ischemic stroke and transient ischemic attack. We selected the first 30 videos from each search query for further analysis. The validated DISCERN instrument was used (a score of 0-5 per question) to assess the videos by four independent raters. We then recorded qualitative data and quantitative data for each video. Results After sorting through 150 stroke videos, a total of 101 unique YouTube videos met our inclusion criteria. We found that the mean overall quality of YouTube videos according to DISCERN is of fair quality. Most videos (65.3%) were uploaded by hospitals, mentioned the symptoms of stroke (66.3%), had a doctor speaking (60.4%) and contained diagrams (20.8%). Conclusion YouTube is a useful source of gathering information about treatment choices for patients and their families as the quality of YouTube videos is fair. The Audience Engagement suggestions in our paper may help content creators improve the appeal of YouTube videos.

youtube as a source of patient information for coronavirus disease covid 19 a content quality and Audience Engagement analysis
Reviews in Medical Virology, 2020Co-Authors: Tomasz Szmuda, Shan Ali, Mohammad Talha Syed, Akshita Singh, Cathrine Ozdemir, Pawel SloniewskiAbstract:YouTube is the second most popular website in the world and is increasingly being used as a platform for disseminating health information. Our aim was to evaluate the content-quality and Audience Engagement of YouTube videos pertaining to the SARS (severe acute respiratory syndrome)-CoV-2 virus which causes the Coronavirus Disease 2019 (COVID-19), during the early phase of the pandemic. We chose the first 30 videos for seven different search phrases: "2019 nCoV," "SARS CoV-2," "COVID-19 virus," "coronavirus treatment," "coronavirus explained," "what is the coronavirus" and "coronavirus information." Video contents were evaluated by two independent medical students with more than 5 years of experience using the DISCERN instrument. Qualitative data, quantitative data and upload source for each video was noted for a quality and Audience Engagement analysis. Out of the total 210 videos, 137 met our inclusion criteria and were evaluated. The mean DISCERN score was 31.33 out of 75 possible points, which indicates that the quality of YouTube videos on COVID-19 is currently poor. There was excellent reliability between the two raters (intraclass correlation coefficient = 0.96). 55% of the videos discussed prevention, 49% discussed symptoms and 46% discussed the spread of the virus. Most of the videos were uploaded by news channels (50%) and education channels (40%). The quality of YouTube videos on SARS-CoV-2 and COVID-19 is poor, however, we have listed the top-quality videos in our article as they may be effective tools for patient education during the pandemic.

message design and Audience Engagement with tobacco prevention posts on social media
Journal of Cancer Education, 2018Co-Authors: Yulia A Strekalova, Rachel E DamianiAbstract:Understanding the appropriate medium to communicate health promotion messages is vital for improving personal and societal health. As increasingly more people utilize social media for health information, public health practitioners use these platforms to engage an existing Audience in health promotion messages. In this study, the relational framing theory was used as a lens for studying how message framing may influence social media Audience Engagement. Specifically, we assessed how posts from Tobacco Free Florida’s Facebook page were framed as either dominant-submissive or affiliate-disaffiliate to an implied Audience of either smokers, nonsmokers, active quitters, or a mixed Audience, and the extent to which a direct call for Engagement, in terms of a request to comment, like, or share the post, was used for Audience Engagement. A three-way interaction for the level of Engagement through comments was significant, F(3217) = 7.11, p < .001, ηp 2 = .09, and showed that framing, a call for Engagement, and varying implied Audience choice played a role in Audience Engagement with smoking cessation posts on social media. Implied Audiences of Tobacco Free Florida’s posts included smokers, those who are trying to quit, and nonsmokers as health promotion can be targeted at the individual’s health, social support infrastructure, or the well-being of the society, and implications for strategic message design and Audience targeting are discussed.

emergent health risks and Audience information Engagement on social media
American Journal of Infection Control, 2016Co-Authors: Yulia A StrekalovaAbstract:Social media can effectively reach large Audiences and serve as an indicator for the public's sentiment and Engagement in situations of disease outbreaks. This study used Centers for Disease Control and Prevention (CDC) Facebook posts between March 18 and October 31, 2014, surrounding the 2014 Ebola outbreak, to look at the Audience Engagement with online health information. The CDC submitted fewer posts about Ebola than about non-Ebola topics, but Audience Engagement with Ebola posts was significantly higher, and men were more interested in Ebola posts and submitted more comments per user.

enhancing Audience Engagement through immersive 360 degree videos an experimental study
International Conference on Augmented Cognition, 2018Co-Authors: Ayoung Suh, Guan Wang, Christian WagnerAbstract:The use of 360-degree videos to engage Audiences in diverse contexts is increasing. While 360-degree videos have the potential to create new value in enhancing Audiences’ viewing experiences, they often decrease Audience Engagement by causing motion sickness in an immersive environment. Despite increasing scholarly and practical attention to the effect of 360-videos on Audience Engagement, the question of how to enhance it through immersive 360-degree videos remains unanswered. Therefore, this study empirically examined the effects of different display types and viewport dynamics on Audience Engagement using data collected from 60 subjects during a laboratory experiment. The results show that an Audience’s viewing experience in an immersive environment is influenced by the joint effects of display types and viewport dynamics. By explaining the mechanisms by which Audiences are engaged with 360-degree videos, this study contributes to resolving previous inconsistent findings regarding the effect of immersive technology on Audience Engagement.

the effects of 360 degree vr videos on Audience Engagement evidence from the new york times
International Conference on HCI in Business, 2018Co-Authors: Guan Wang, Ayoung SuhAbstract:This study examines the current application of 360-degree VR videos in the news industry. Both the advantages and challenges of 360-degree VR videos in enhancing Audience experiences and Engagement are discussed. To better understand the effects of immersive technology on Audience Engagement, this study selects the case of The New York Times (NYT). Data were crawled from 598 videos on the NYT YouTube account for analyses. The results showed that 360-degree VR videos generally performed worse than non-VR videos in enhancing Audience Engagement. An interaction effect was found between video format (360-degree VR or non-VR) and content genres.

mental health message appeals and Audience Engagement evidence from australia
Health Promotion International, 2019Co-Authors: Jo En Yap, Nives Zubcevicbasic, Lester W Johnson, Michaela A LodewyckxAbstract:Social media platforms are increasingly used to disseminate social marketing messages about mental health and wellbeing. This study presents a range of message appeals used in social media enabled mental health promotion and stigma reduction messages. Furthermore, it examines the relationship between the type of message appeals and Audience Engagement. A content analysis of 65 organisation-generated YouTube videos about depression and anxiety and stigma reduction was conducted. The most utilised message appeal was Sorrow, followed by Affiliation, Ease/Convenience, Hope, Humour, Guilt/Shame, Heroic/Successful, and Fear. Multiple regression analysis was used to examine the relationship between the type of message appeals and Audience Engagement in terms of the number of likes, comments, and shares. The analysis revealed that Sorrow is the most useful message appeal for generating Audience comments. However, Sorrow is negatively associated with the number of likes and shares. The results suggest that mental health promotion messages may engage a larger Audience through Affiliation and Hope as they have a positive impact on the number of shares. This could, in effect, turn Audiences into vocal advocates for mental health promotion and stigma reduction messages.
