ABSTRACT

OBJECTIVE: The COVID-19 pandemic is the first pandemic where social media platforms relayed information on a large scale, enabling an "infodemic" of conflicting information which undermined the global response to the pandemic. Understanding how the information circulated and evolved on social media platforms is essential for planning future public health campaigns. This study investigated what types of themes about COVID-19 were most viewed on YouTube during the first 8 months of the pandemic, and how COVID-19 themes progressed over this period. METHODS: We analyzed top-viewed YouTube COVID-19-related videos in English from December 1, 2019 to August 16, 2020 with an open inductive content analysis. We coded 536 videos associated with 1.1 billion views across the study period. East Asian countries were the first to report the virus, while most of the top-viewed videos in English were from the US. Videos from straight news outlets dominated the top-viewed videos throughout the outbreak, and public health authorities contributed the fewest. Although straight news was the dominant COVID-19 video source with various types of themes, its viewership per video was similar to that for entertainment news and YouTubers after March. RESULTS: We found, first, that collective public attention to the COVID-19 pandemic on YouTube peaked around March 2020, before the outbreak peaked, and flattened afterwards despite a spike in worldwide cases. Second, more videos focused on prevention early on, but videos with political themes increased through time. Third, regarding prevention and control measures, masking received much less attention than lockdown and social distancing in the study period. CONCLUSION: Our study suggests that a transition of focus from science to politics on social media intensified the COVID-19 infodemic and may have weakened mitigation measures during the first waves of the COVID-19 pandemic. It is recommended that authorities should consider co-operating with reputable social media influencers to promote health campaigns and improve health literacy. In addition, given high levels of globalization of social platforms and polarization of users, tailoring communication towards different digital communities is likely to be essential.

ABSTRACT

OBJECTIVES: With the expansion of the internet, social media platforms have become a major source of medical information. However, medical information on online multimedia platforms is often inaccurate. In the current study, we evaluated the reliability, quality, and accuracy of the most viewed YouTube videos featuring the effects of vitamin C on COVID-19. METHODS: A search was conducted on YouTube on January 13, 2022, using the keywords ("ascorbic acid" OR "vitamin C" OR "sodium ascorbate" OR "L-ascorbic") AND ("coronavirus" OR "COVID 19" OR "COVID-19" OR "Corona" OR "COVID" OR "SARSCoV2"). We assessed the 50 most-viewed videos using a modified DISCERN scale (mDISCERN) and Global Quality Scale (GQS). Additionally, the accuracy of the information in each video was evaluated. RESULTS: Out of the 50 most-viewed videos featuring the effect of vitamin C on COVID-19, 54% were not reliable. Furthermore, 62% presented poor quality, and 74% were misleading or neither accurate nor misleading. The average mDISCERN and GQS scores of the 50 included videos were 2.2 ± 1.4 (≥ 3: highly reliable) and 2.2 ± 1.1 (2: generally poor), respectively. Although the videos were made by medical doctors, their reliability, quality, and accuracy were not significantly different from those displayed in other sources, including fitness channels, television or internet-based news or programs, consumers, company channels, product advertisements, or prepared by nurses. CONCLUSIONS: The reliability, quality, and accuracy of the 50 most-viewed videos on the effect of vitamin C on COVID-19 were not high. Video creators, especially medical doctors, should make an effort so that the videos present reliable content with high-quality and correct information is disseminated to people.

ABSTRACT

OBJECTIVE: Describe the usability, actionability and understanding of videos to promote exercise at home online during the COVID-19 pandemic, analyzing the characteristics of the population, their satisfaction, adherence and barriers to physical exercise. MATERIAL AND METHODS: A descriptive, non-experimental and cross-sectional observational design study, with a quantitative approach. Home-based videos of physical exercise and education about pain were created for people over 60 years old and distributed in the Metropolitan Region (Chile) during the months of October to December 2020. Participants had to use these videos independently at home during 4 weeks. A sample who received these videos were then voluntarily surveyed. RESULTS: Thirty-four participants rated the videos as understandable and actionable. Usability was lower in people who perceived a lower level of technological management. Average adherence was 2 days a week for 2.5 weeks. The main perceived barrier was the lack of will, which showed a greater tendency in people who performed physical exercise in a group way before the restrictions due to the COVID-19 pandemic. CONCLUSIONS: The videos were well evaluated by the elderly population, however the technological gap can be a limitation to favor an easy and simple use. Among the strategies, interventions that favor social interaction should be considered to promote interpersonal motivation, especially in people who prefer group modalities of exercise.

ABSTRACT

BACKGROUND: Regenerative endodontic procedures (REPs) are one of the most important developments in dental practice, and in the era of Covid 19 pandemic, audio-visual contents of YouTube™ could be an information source for dental students, practitioners and patients. The aim of this study was to evaluate the quality, content and the demographics of YouTube™ videos about REPs. METHODS: A search on YouTube™ was performed for REPs using "endodontic regeneration", "pulp regeneration", "regenerative endodontics", "regenerative endodontic procedures", "revascularization" and "revitalization" keywords. Totally 531 videos were found and 60 videos met the inclusion criteria. Following the assessment of the demographic features of the videos and the viewing rate of the videos were calculated. The content of the videos was evaluated based on the selected headings. The quality of the videos was assessed using the video information, quality index (VIQI), Global Quality Score (GQS) and DISCERN. The statistical analysis was performed using Spearman Correlation and linear regression analysis. RESULTS: Majority of the videos about REPs were created by dental professionals (91.7%). The most commonly covered topic was "clinical application" (76.7%). Total content score showed a positive correlation with total VIQI (r = 0.795; p < 0.001) and GQS (r = 0.952; p < 0.001). There were significant relationships between total content score, duration, GQS, total VIQI score and DISCERN. CONCLUSION: The findings revealed that YouTube™ videos about REPs provide predominantly clinical information about patient chairside practice of REPs and they could be considered as a supplementary information source for dental students and practitioners.

ABSTRACT

Current day youth have an important role in climate activism, as the decisions and policies made now will have long lasting impacts on the climate and sustainability. Climate change is becoming an increasing concern for younger generations. As such, the purpose of this study was to describe content related to climate change on TikTok. This study included 100 English-language videos related to climate change featured on TikTok. The hashtag #climatechange was chosen because it had the most views of any related hashtag at the time of the study. The number of views, comments, and likes were recorded for each video. Each video was also observed for the presence of predetermined content characteristics. The 100 videos sampled collectively received 205,551,200 views, 40, 203,400 likes, and 666,089 comments. Only eight of the 100 videos included information from a reputable source. Only three of the characteristics were featured in a majority (> 50) of the videos. These were, presents climate change as real (93), affected populations (76), and climate anxiety/frustration (57). Videos mentioning natural disasters garnered 63,453,100 (30.87%) views, 14,245,200 (35.43%) likes, and 236,493 (35.50%) comments. In all, 73 of the 100 videos mentioned at least one environmental impact. Videos including this theme earned 156,677,200 (76.22%) views, 32,000,700 (79.60%) likes, and 563,195 (84.55%) comments. Social media platforms such as TikTok are important tools for understanding popular opinion regarding public health issues such as global climate change. However, the presence of credible professionals is essential on platforms such as TikTok to increase the chances that messaging is as comprehensive as time allows, while also being scientifically sound.

ABSTRACT

Epidemiological evidence and recommendations from the World Health Organization suggest that close face-to-face interactions pose a particular coronavirus transmission risk. The real-life prevalence and nature of such high-risk contacts are understudied, however. Here, we video-observed high-risk contacts in outdoor public places in Amsterdam, the Netherlands, during the COVID-19 pandemic. We found that high-risk contacts were relatively uncommon: Of the 7,813 individuals observed, only 20 (0.26%) displayed high-risk contacts. Further, we qualitatively examined the 20 high-risk contacts identified and found that they occurred disproportionally between affiliated persons engaged in affiliative behaviors. We discuss the potential public health implications of the relatively low incident rate of high-risk contacts.

ABSTRACT

INTRODUCTION: Vaccines for SARS-CoV-2 have been accessible to the public since December 2020. However, only 58.3% of Americans are fully vaccinated as of 5 November 2021. Numerous studies have supported YouTube as a source of both reliable and misleading information during the COVID-19 pandemic. Misinformation regarding the safety and efficacy of COVID-19 vaccines has negatively impacted vaccination intent. To date, the literature lacks a systematic evaluation of YouTube's content on COVID-19 vaccination using validated scoring tools. The objective of this study was to evaluate the accuracy, usability and quality of the most widely viewed YouTube videos on COVID-19 vaccination. METHODS: A search on YouTube was performed on 21 July 2021, using keywords 'COVID-19 vaccine' on a cleared-cache web browser. Search results were sorted by 'views', and the top 150 most-viewed videos were collected and analysed. Duplicate, non-English, non-audiovisual, exceeding 1-hour duration, or videos unrelated to COVID-19 vaccine were excluded. The primary outcome was usability and reliability of videos, analysed using the modified DISCERN (mDISCERN) score, the modified Journal of the American Medical Association (mJAMA) score and the COVID-19 Vaccine Score (CVS). RESULTS: CONCLUSION: As the COVID-19 pandemic evolves, widespread adoption of vaccination is essential in reducing morbidity, mortality, and returning to some semblance of normalcy. Providing high-quality and engaging health information from reputable sources is essential in addressing vaccine hesitancy.

ABSTRACT

This study evaluates the progression of visual fatigue induced by visual display terminal (VDT) using automatically detected blink features. A total of 23 subjects were recruited to participate in a VDT task, during which they were required to watch a 120-min video on a laptop and answer a questionnaire every 30 min. Face video recordings were captured by a camera. The blinking and incomplete blinking images were recognized by automatic detection of the parameters of the eyes. Then, the blink features were extracted including blink number (BN), mean blink interval (Mean_BI), mean blink duration (Mean_BD), group blink number (GBN), mean group blink interval (Mean_GBI), incomplete blink number (IBN), and mean incomplete blink interval (Mean_IBI). The results showed that BN and GBN increased significantly, and that Mean_BI and Mean_GBI decreased significantly over time. Mean_BD and Mean_IBI increased and IBN decreased significantly only in the last 30 min. The blink features automatically detected in this study can be used to evaluate the progression of visual fatigue.

ABSTRACT

OBJECTIVES: to identify the contents and characteristics of videos posted on YouTube that deal with Iramuteq software use as a tool to assist qualitative research and discuss the contribution of this social network to dissemination of knowledge, especially in the context of the COVID-19 pandemic. METHOD: this is an exploratory-descriptive study with a qualitative approach, carried out with YouTube videos, collected in June 2021 and subjected to thematic analysis. RESULTS: a total of 43 videos on the researched topic were identified, with the majority (69.76%) published from 2020-2021. As for content, five categories were identified. CONCLUSION: the videos explain about Iramuteq installation, the textual corpus preparation, the errors identified by users and methods to correct them, the lexical analysis developed by the program and how to use it. The content is presented in a theoretical and practical way through the software interface presentation. Thus, YouTube's contribution to developing teaching and disseminating knowledge is observed, both because it constitutes itself as a source for research and because it fosters dialogues between researchers, especially in a pandemic context.

ABSTRACT

The digitalization process for organizations, which was inevitably accelerated by the COVID-19 pandemic, raises relevant challenges for Human Resource Management (HRM) because every technological implementation has a certain impact on human beings. Between many organizational HRM practices, recruitment and assessment interviews represent a significant moment where a social interaction provides the context for evaluating candidates' skills. It is therefore relevant to investigate how different interaction frames and relational conditions affect such task, with a specific focus on the differences between face-to-face (FTF) and remote computer-mediated (RCM) interaction settings. In particular, the possibility of qualifying and quantifying the mechanisms shaping the efficiency of interaction in the recruiter-candidate dyad-i.e. interpersonal attunement-is potentially insightful. We here present a neuroscientific protocol aimed at elucidating the impact of FTF vs. RCM modalities on social dynamics within assessment interviews. Specifically, the hyperscanning approach, understood as the concurrent recording and integrated analysis of behavioural-physiological responses of interacting agents, will be used to evaluate recruiter-candidate dyads while they are involved in either FTF or RCM conditions. Specifically, the protocol has been designed to collect self-report, oculometric, autonomic (electrodermal activity, heart rate, heart rate variability), and neurophysiological (electroencephalography) metrics from both inter-agents to explore the perceived quality of the interaction, automatic visual-attentional patterns of inter-agents, as well as their cognitive workload and emotional engagement. The proposed protocol will provide a theoretical evidence-based framework to assess possible differences between FTF vs. RMC settings in complex social interactions, with a specific focus on job interviews.

ABSTRACT

Objective: During the current coronavirus disease 2019 (COVID-19) pandemic, telemedicine has been brought to the forefront of attention. This report aimed to assess psychiatric comorbidities in COVID-19 patients by utilizing telepsychiatry. Methods: COVID-19 patients admitted in Fasa University Hospital and nonhospitalized outpatients of Fasa city were interviewed by a psychiatrist through video chat for a 1-month period (March-April, 2020). Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Assessment (GAD-7), and Perceived Stress Scale-14 (PSS 14) questionnaires were administered for all patients. Each patient's mental status was recorded, and if any psychiatric problem was diagnosed, supportive psychotherapy, pharmacotherapy, and follow-up visits based on the patient's condition were started. Result: From a total of 82 COVID-19 patients who entered the study, 32 (39.03%) and 50 (60.97%) subjects were inpatients and outpatients, respectively. Moreover, 32 (39.03%) subjects were male and 50 (60.97%) were female. Insomnia seen in 24 (29.3%) patients and adjustment disorder in 13 (15.9%) patients were the most common psychiatric disorders among a total of 33 (40.2%) patients suffering from mental illness. Female and hospitalized patients presented significantly more frequent comorbidities than males and outpatients. Conclusions: Psychiatric disorders were significantly more common in patients with hospital admission than those without and more frequent in female versus male subjects. There were no significant differences between male and female subjects with and without admission according to the PHQ-9, GAD-7, and PSS-14 scores. It was concluded that telepsychiatry in the early stages of mental problems during a catastrophic event like the coronavirus pandemic, can be an efficient instrument for the screening of psychosomatic comorbidities, so that pharmacological treatment (considering possible drug interactions with COVID-19 medications) and psychotherapeutic intervention can be optimized by psychiatrists.

ABSTRACT

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has become one of the most critical public health problems worldwide. Because many COPD patients are using video-based social media to search for health information, there is an urgent need to assess the information quality of COPD videos on social media. Recently, the short-video app TikTok has demonstrated huge potential in disseminating health information and there are currently many COPD videos available on TikTok; however, the information quality of these videos remains unknown. OBJECTIVE: The aim of this study was to investigate the information quality of COPD videos on TikTok. METHODS: In December 2020, we retrieved and screened 300 videos from TikTok and collected a sample of 199 COPD-related videos in Chinese for data extraction. We extracted the basic video information, coded the content, and identified the video sources. Two independent raters assessed the information quality of each video using the DISCERN instrument. RESULTS: COPD videos on TikTok came mainly from two types of sources: individual users (n=168) and organizational users (n=31). The individual users included health professionals, individual science communicators, and general TikTok users, whereas the organizational users consisted of for-profit organizations, nonprofit organizations, and news agencies. For the 199 videos, the mean scores of the DISCERN items ranged from 3.42 to 4.46, with a total mean score of 3.75. Publication reliability (P=.04) and overall quality (P=.02) showed significant differences across the six types of sources, whereas the quality of treatment choices showed only a marginally significant difference (P=.053) across the different sources. CONCLUSIONS: The overall information quality of COPD videos on TikTok is satisfactory, although the quality varies across different sources and according to specific quality dimensions. Patients should be selective and cautious when watching COPD videos on TikTok.

ABSTRACT

Neglecting oral hygiene in adolescents negatively affects dental caries and periodontal diseases, in addition to social and emotional well-being. Thus, the TikTok platform (ByteDance, Beijing, China)as a social media could be a powerful channel to provide health-related information and educational content. This study aims to assess the quality of the TikTok videos corresponding to #oralhealtheducation. Sixty-nine videos were identified. Three oral health professionals (OHP), three health education professionals (HEP), and ten of TikTok's target audience watched and evaluated the videos from a qualitative questionnaire. OHP detected false or incorrect information in 11.6% (8/69) of the videos. At least two HEPs reported being unable to detect this type of content or whether the video met dental ethics standards in both the videos. Disagreement was observed among the professionals themselves. The evaluation indicated that TikTok's target audience was satisfied with the products viewed with an average score of >2.5, unlike the professionals, whose average score was <2.5 on a scale of 0 to 5. Users are advised to think critically and to consider the content of TikTok oral health videos with caution. The involvement of health professionals in the writing and validation of the videos could be an added value to positively respond to the needs of the adolescents.

ABSTRACT

INTRODUCTION: There are many possible sources of medical information; however, the quality of the information varies. Poor quality or inaccurate resources may be harmful if they are trusted by providers. This study aimed to analyze the quality of coronavirus disease 2019 (COVID-19)-related intubation videos on YouTube. METHODS: The term "COVID-19 intubation" was searched on YouTube. The top 100 videos retrieved were sorted by relevance and 37 videos were included. The video demographics were recorded. The quality of the videos was analyzed using an 18-point checklist, which was designed for evaluating COVID-19 intubation. Videos were also evaluated using general video quality scores and the modified Journal of the American Medical Association score. RESULTS: The educational quality was graded as good for eight (21.6%) videos, moderate for 13 (35.1%) videos, and poor for 16 (43.2%) videos. The median safe COVID-19 intubation score (SCIS) was 11 (IQR = 5-13). The SCISs indicated that videos prepared in an intensive care unit were higher in quality than videos from other sources (p < 0.05). The length of the video was predictive of quality (area under the curve = 0.802, 95% CI = 0.658-0.945, p = 0.10). CONCLUSIONS: The quality of YouTube videos for COVID-19 intubation is substandard. Poor quality videos may provide inaccurate knowledge to viewers and potentially cause harm.

ABSTRACT

BACKGROUND: The correct use of personal protective equipment (PPE) during the Covid-19 pandemic is mandatory to minimize the contagion risk. The current study aimed to evaluate quality information of YouTube videos on PPE use during the pandemic. METHODS: Using Google Trend tool, the frequency of worldwide YouTube and Google searches for "donning and doffing" was examined. We queried YouTube with terms related to donning and doffing of PPE. Validated quality information assessment tools were used. RESULTS: From the December 1, 2019 to the January 31, 2021, according to YouTube and Google searches, both peaks occurred in April 2020 (69.5% and 72.0%, respectively). Of all videos, 144 were eligible for the analyses. According to misinformation tool, 90 (62.5%) videos contained inaccuracies. The median DISCERN Section 1 ranged from 3 to 5. The median DISCERN Section 3 was 4. According to Global Quality Score, 8.3% (n = 12), 14.6% (n = 21), 22.9% (n = 33), 30.6% (n = 44) and 23.6% (n = 34) were classified as poor, partially poor, moderate, partially good and excellent quality videos, respectively. CONCLUSIONS: Nowadays, YouTube may be recommended as a reliable source of information. Nevertheless, a not negligible number of videos contained inaccuracies. Future authors should improve videos contents to provide more complete information.
