Social Media Growth Blueprint for Plastic Surgeons: Insights and Considerations From Personal Experience.

Social media platforms such as TikTok have recently emerged as influential tools for information dissemination, offering plastic surgeons new opportunities to promote their practices. However, these platforms also present significant challenges regarding online safety, ethical considerations, and the potential spread of misinformation. This study analyzes the experience of gaining 100,000 followers on TikTok within 6 months, highlighting the excitement of rapid growth alongside the challenges posed by the potential for misinformation. We propose a strategic approach to leveraging social media effectively and ethically, focusing on storytelling, educational content, and audience engagement; highlighting unique selling propositions; utilizing analytics; and maintaining consistency. Ethical considerations in medical communication are also discussed, emphasizing the need for robust guidelines. From December 2023 to June 2024, the author posted 56 videos in Arabic, the target market's language. These videos garnered 16,566,900 views and 758,500 likes, with an average video length of 95.36 seconds. This growth led to a 47% increase in nonsurgical aesthetic consultations. Engagement and educational content, such as study tips, received the highest views, totaling 5.6 million, demonstrating the importance of such content in building a follower base for targeted marketing. Our findings highlight the power and potential risks of social media in healthcare, advocating for a balanced approach that maximizes benefits while mitigating the spread of misinformation.

Comparative evaluation of 2D and 3D YouTube videos as supplementary educational resources for vitreoretinal surgery training.

Ophthalmologists and ophthalmology residents (ORs) are increasingly turning to the internet for medical information, underscoring the significant role that YouTube videos, particularly three-dimensional (3D) ones, play in lifelong learning. This study aimed to compare the content and quality of 3D YouTube videos with two-dimensional (2D) videos as supplementary educational tools for vitreoretinal surgery. Data collected included video length (minutes), time elapsed since upload (days), number of views, likes, dislikes, vitreoretinal surgery type, and visualization system. Video popularity and interaction were calculated using the video power index, interaction index, and viewing rate. Two senior ophthalmologists (SOs) and 2 ORs evaluated the videos using the DISCERN, Global Quality Score, and usefulness scoring systems. Inter-rater reliability was assessed using the intra-class correlation coefficient. A total of 392 videos were screened, with 67 2D and 67 3D videos deemed appropriate for inclusion. While 2D videos had significantly more views, likes, interaction index, and viewing rate than 3D videos (P < .001 for all), 3D videos were rated higher by ORs across all scoring systems (P < .05 for all). Inter-rater reliability was confirmed to be good, with the lowest intra-class correlation coefficient being 0.796 for SOs (95% confidence interval: 0.668-0.875) and 0.814 for ORs (95% confidence interval: 0.698-0.886). In conclusion, side-by-side 3D YouTube videos offer a valuable supplementary educational tool, enhancing depth perception and enabling both SOs and ORs to better understand the complexities of ocular surgeries, particularly vitreoretinal procedures. These videos can also be used to observe new procedures and refresh previously acquired knowledge of past surgeries.

The Assessment of TikTok as a Source of Quality Health Information on Human Papillomavirus: A Content Analysis.

Background Various studies have evaluated the quality of health-related information on TikTok (ByteDance Ltd., Beijing, China), including topics such as COVID-19, diabetes, varicoceles, bladder cancer, colorectal cancer, and others. However, there is a paucity of data on studies that examined TikTok as a source of quality health information on human papillomavirus (HPV). This study, therefore, evaluated the quality of health information on HPV on TikTok. Methods The terms "HPV" and "human papillomavirus" were searched on TikTok on a single day in August 2024, and 200 videos were retrieved. Relevant user metrics were collected for each video, including the number of likes, shares, and followers, the video length, and the uploader type. Two independent raters assessed each video regarding the completeness of six types of content (the definition of HPV, symptoms, risk factors, evaluation, management, and outcomes). Then, the two raters independently assessed the quality of information in the videos using the DISCERN instrument. Results Sixty-nine videos met inclusion criteria; 11 were created by general users, 44 by healthcare professionals, and 14 by organizations. Videos uploaded by general users and health professionals have a longer duration (p < 0.001) and more likes (p = 0.048) than those uploaded by organizations. More than 60% of the videos contained little or no content on the HPV content assessed. Although the reliability and quality of treatment choices were higher among videos uploaded by healthcare professionals, the overall quality of HPV health information using the DISCERN instrument was "very poor" (24.2 (±6.92)). Conclusions The overall quality of HPV videos uploaded on TikTok is very poor and not acceptable, thus failing to satisfy public health needs. Healthcare professionals must enhance their social media presence, produce reliable and substantive material, and collaborate with social media platforms and high-engagement accounts to facilitate users' access to high-quality data. TikTok users must recognize that material regarding HPV may lack medical accuracy and should consistently consult healthcare providers for medical guidance.

Evaluating Online YouTube Videos for Cervical Cancer Brachytherapy Patient Education.

Cervical cancer remains the fourth most frequently diagnosed cancer worldwide, with brachytherapy an important modality of treatment. Patients often rely on YouTube for cancer-related information, yet few studies have evaluated these videos. This study aims to describe and evaluate YouTube videos available to patients relating to cervical cancer brachytherapy.YouTube was searched using pre-defined cervical cancer brachytherapy search terms in January, 2023. Videos were sorted by relevance and the first 50 videos from each search were collected. Duplicates were removed and exclusion criteria applied. Videos were evaluated for general parameters, source information, and content. Descriptive analyses were carried out.47 unique videos were included in the analysis. Around half of videos were published within 3 years of the search date. Median video length was 4min and 42s. Commonly, videos were published in the USA (55%). Two-thirds of videos were aimed towards a patient audience. Overall, the content of 40% of videos related to cervical cancer, 94% related to radiation therapy including brachytherapy, and 51% directly related to the use of brachytherapy in the treatment of cervical cancer. Only 15% of videos overviewed the patient-relevant information of brachytherapy side effects. Some videos (13%) were advertisements and few (4%) contained grossly inaccurate information.Videos collectively presented an overview of the treatments for cervical cancer including brachytherapy, although few included pertinent patient-relevant information and some contained inaccurate information. Overall, this highlights the need for more clear, accurate, and patient education-focused online resources.

Representing Long Volumetric Video with Temporal Gaussian Hierarchy

This paper aims to address the challenge of reconstructing long volumetric videos from multi-view RGB videos. Recent dynamic view synthesis methods leverage powerful 4D representations, like feature grids or point cloud sequences, to achieve high-quality rendering results. However, they are typically limited to short (1~2s) video clips and often suffer from large memory footprints when dealing with longer videos. To solve this issue, we propose a novel 4D representation, named Temporal Gaussian Hierarchy, to compactly model long volumetric videos. Our key observation is that there are generally various degrees of temporal redundancy in dynamic scenes, which consist of areas changing at different speeds. Motivated by this, our approach builds a multi-level hierarchy of 4D Gaussian primitives, where each level separately describes scene regions with different degrees of content change, and adaptively shares Gaussian primitives to represent unchanged scene content over different temporal segments, thus effectively reducing the number of Gaussian primitives. In addition, the tree-like structure of the Gaussian hierarchy allows us to efficiently represent the scene at a particular moment with a subset of Gaussian primitives, leading to nearly constant GPU memory usage during the training or rendering regardless of the video length. Moreover, we design a Compact Appearance Model that mixes diffuse and view-dependent Gaussians to further minimize the model size while maintaining the rendering quality. We also develop a rasterization pipeline of Gaussian primitives based on the hardware-accelerated technique to improve rendering speed. Extensive experimental results demonstrate the superiority of our method over alternative methods in terms of training cost, rendering speed, and storage usage. To our knowledge, this work is the first approach capable of efficiently handling hours of volumetric video data while maintaining state-of-the-art rendering quality.

The Centering of Youth Voice in the Development of a Virtual, Instructor-Led Physical Activity Program.

Providing youth the opportunity to express their attitudes toward and recommendations for improvement of a home-based physical activity (PA) program may help to improve engagement in virtual PA program activities. Youth voice is an often-overlooked component that may be necessary for understanding what contributes to low participation and may have important implications for long-term adherence. Informed by Self-Determination Theory, this study aimed to formatively evaluate home-based exercise videos, incorporating youth feedback for improvement in the development of the videos. Youth participated in four (8-minute) PA videos varying in type (strength; cardio; mindfulness; sports skill). Youth accessed the videos and answered open-ended questions via an online survey. Data were analyzed using qualitative content analysis to identify emerging themes in responses. Sixty-eight K-12 youth in the United States (52% girls; 38% non-White; 55% in K-5 grade; 17% in 6-8 grade; 28% in 9-12 grade) participated in this study. Overall, 61.9% of affective responses were positive, with mindfulness rating the highest and strength the lowest. Children were satisfied with the video structure, enjoyed having an opportunity to move at home and reported liking the engaging instructors. Suggestions were also given related to modifying video length, adding modifications for varying fitness levels, adding more kid-like features, and providing incentives. Youth recommendations may be used to create tailored adaptations and implementation supports for PA programs in the home. Findings from this study demonstrate that incorporating youth voice may be an important step toward increasing engagement in home-based PA programming.

YouTube as a source of information in cardiopulmonary resuscitation for 2020 AHA Resuscitation Guidelines.

The Internet has transformed global information access, particularly through platforms like YouTube, which launched in 1995 and has since become the second largest search engine worldwide with over two billion monthly users. While YouTube offers extensive educational content, including health topics like cardiopulmonary resuscitation (CPR) and basic life support (BLS), it also poses risks due to potential misinformation. Our study focuses on evaluating the accuracy of CPR and BLS videos on YouTube according to the latest 2020 American Heart Association (AHA) guidelines. This research aims to highlight inconsistencies and provide insights into improving YouTube as a reliable educational resource for both lay rescuers and healthcare professionals. In this cross-sectional observational study, English YouTube videos uploaded between October 21, 2020, and May 1, 2023, were searched using keywords related to CPR and basic life support. Videos were assessed for their source, duration, views, use of human or mannequin models, and mean assessment scores by two emergency medicine physicians. A third physician's opinion was sought in cases of disagreement. The first assessment evaluated video validity based on specified information criteria, while the second assessed their ability to convey advanced medical information aligned with the 2020 AHA guidelines. In this study, 201 English YouTube videos uploaded between October 21, 2020, and May 1, 2023, were evaluated based on search terms related to CPR and BLS, resulting in 95 videos meeting inclusion criteria after excluding 106 due to various reasons. Most included videos were from healthcare professionals (49.5%), followed by anonymous sources (29.5%) and official medical organizations (21.1%). Video durations ranged widely from 43 to 6,019 seconds, with an average of 692 seconds. Videos featuring mannequins predominated (91.6%), followed by those using human subjects (5.3%) or both (3.2%). Healthcare professional and official medical organization videos scoring significantly higher than those of unknown origin (p=0.001). Video length did not correlate significantly with view counts, although shorter videos under 5 minutes tended to have higher average views. The results presented in this study demonstrated that English-language videos on YouTube related to BLS and CPR, throughout the study period, did not conform to the 2020 AHA guidelines in terms of providing basic information for lay rescuers. Furthermore, healthcare professionals cannot obtain advanced medical knowledge through these videos. We recommend a professional oversight mechanism in health-related videos that does not tolerate such misinformation.

Evaluation of the Educational Quality of Endonasal Endoscopic Dacryocystorhinostomy Videos on YouTube with IVORY and LAP-VEGaS Guidelines.

Objective: The aim of this study was to evaluate the educational quality of endonasal endoscopic dacryocystorhinostomy (EE-DCR) videos on YouTube with Instructional Videos in Otorhinolaryngology by YO-IFOS (IVORY) and LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) guidelines and to evaluate the correlation of the 2 guidelines. Methods: EE-DCR videos were queried using search terms on YouTube. Views, likes, likes/dislikes ratio, age, and length of videos were noted. Videos were evaluated using the IVORY and LAP-VEGaS guidelines. Two IVORY scores were created: total (IVORY-1) and organ-specific (IVORY-2). The correlation analysis between video features and guideline scores was performed. Results: A total of 61 EE-DCR videos were evaluated. The mean score of LAP-VEGaS was 10.3 (±SD 2.7), the mean IVORY-1 score was 22.5 (±SD 5.5), and the mean IVORY-2 score was 10.6 (±SD 1.94). Correlation analysis revealed a statistically significant correlation between the IVORY-1 total score and the number of likes, the duration of the video, the age of the video, and the LAP-VEGaS score. Linear regression analysis showed that higher IVORY-1 scores predicted longer video duration, newer video age, and higher LAP-VEGaS scores. There was a significant association between LAP-VEGaS categories and the IVORY-1 total score (P < .001). Conclusion: The quality of EE-DCR videos is generally low to moderate. The IVORY and LAP-VEGaS guidelines were found to be correlated with each other. Both guidelines can be used to evaluate EE-DCR videos and otolaryngology surgical education videos in general. We believe that scales such as IVORY and LAP-VEGaS may be improved according to specific surgical procedures.

Video-based lecture engagement in a flipped classroom environment

Purposeto analyze which factors are associated with students’ engagement and participation in video-based lectures in a flipped classroom environment.MethodsA single-center experience with video-based lectures in undergraduate medical education is described. The activity was applied to the subject of Neurosurgery during two consecutive courses (2021/22 and 2022/23). The videos were available prior to face-to-face classes through the online application Edpuzzle. Information was obtained from the own platform at the end of each course. Multivariable linear regression analyses were performed to assess the association between different variables and the percentage of video viewing, the early dropout rate, and the percentage of audience retention.ResultsA total of 109 students registered in Edpuzzle (87.2% of all enrolled students). Fifty-one videos were uploaded each course to cover 11 topics. Mean video viewing rate was 41%. Those videos linked to the earliest classroom lessons showed more percentage of viewing and audience retention than those programmed at the end of the course. With mandatory classroom assistance and homework assignments, the seminar videos were viewed more but retained less audience. Shorter videos were associated with higher viewing and audience adhesion, but the presence of questions embedded throughout the clip did not significantly engage students. No significant difference was observed regarding lesson topics.ConclusionsIt is essential to emphasize the importance of designing strategies to initially engage learners since more than half of our students never connected to the clips. Decreasing engagement was associated with the end of the course and video length. Seminar videos were viewed more but retained less audience. Active learning activities such as quizzes embedded throughout the clips did not significantly engage learners.

Assessment of YouTube Videos Related to Radioactive Iodine Therapy for Thyroid Cancer for Patient Education.

Thyroid cancer is the most common cancer diagnosis among those aged 15-29, with a noticeable increase in cases over the last decade. YouTube, one of the most frequented websites on the internet, serves as a common platform to obtain health information. This study uses a systematic approach to characterize YouTube videos related to radioactive iodine (RAI) therapy for thyroid cancer. The first 50 videos across four distinct YouTube search terms related to RAI therapy for thyroid cancer were identified after applying exclusion criteria. A previously validated video assessment tool was utilized to evaluate the videos. Two independent reviewers assessed a random sample of 10 videos, while the remaining 40 videos were evaluated by one reviewer as there were minimal discrepancies in coding. Among the identified videos, 26 videos were published within the past 3years, with a median video length of 4min and 53s. The three most common publishers' affiliations were non-profits (15 videos), personal accounts (12 videos), and health care facilities/organizations (11 videos). Most of the videos originated in the United States, used an interview format, featured physician presenters, and were directed towards patients. Highly covered topics included "side effects and risks" and "RAI therapy overview". The findings underscore the significant role YouTube plays in aiding patient comprehension of RAI therapy for thyroid cancer based on video parameters and content. These results can inform physicians' discussions with patients regarding YouTube and contribute to the development of new, high-quality YouTube videos to support thyroid cancer education.

Perceptions of the 2D short animated videos for literacy against chronic diseases among adults with diabetes and/or hypertension: a qualitative study in primary care clinics.

Animation has promise for teaching complex health content through smartphone applications. However, smartphones have had limited use in Thailand for health literacy improvement among adults with chronic diseases. This study aims to explore the perceptions of adults with diabetes and/or hypertension resulting from 2D short animated videos for literacy against chronic disease that are available via smartphones. Four animated videos were initially developed based on clinical practice guidelines and nursing experience. Physicians, an expert in health education, and an animation team developed and revised scripts and storyboards of the animated videos. Lastly, videos were validated by physicians and health educators for content breadth and depth and by media experts for motion graphics and illustration. Each video presents a different situation in diabetes, hypertension, missing appointments, and obesity, ranging from 2.18 to 4.14min in duration. The inclusion criteria were adults 35-70 years old with diabetes or hypertension who received care from primary care units. Thematic analysis was performed on the extracted data. Twenty participants with a mean age of 58.4 years (SD 6.7; ranged 41-68) were focus-group interviewed. Three animation elements were assessed, including presentation, impacts, and suggestions. Participants had positive responses regarding the presentation (suitability of images and smooth motion graphics, short length of videos, simple language, understandable content, and clear sound) and impacts (recalling information, enhancing engagement, and motivating health awareness and behavior change). Suggested improvements were for a bigger font size for subtitles and considering the use of spoken text instead of on-screen text for recommendations at the end of the animations. Animated videos are acceptable for delivering health information. Pilot testing animated videos for promoting literacy against chronic diseases in adults with diabetes and hypertension is needed for optimal utility.

Challenging the Public Stigma of Alcohol Use Disorder in the UK Using Video ‘Education’ and ‘Contact’ Interventions: A Pilot Study

AbstractPublic stigma negatively impacts people with alcohol use disorder; yet, few interventions exist to reduce it. This quasi-randomised controlled pilot study aimed to evaluate the feasibility and efficacy of three such interventions. Participants (539 UK-based adults) watched a video presenting myths and facts about AUD (‘education’), personal testimonies about AUD (‘contact’), a combination of both (‘education and contact’) or a control video. Feasibility was assessed by examining recruitment capability, study retention and data quality, and participant satisfaction with the study’s procedures and interventions. Efficacy was assessed using self-report, public stigma measures issued at pre-test, post-test and 1-month follow-up. Stigma reduced significantly more in the intervention groups than in the control group at post-test and follow-up. Feasibility was generally high, though could be improved by shortening video length and enhancing video production quality. Education and contact videos are promising interventions for public AUD stigma, and merit further investigation.

Descriptive and content analysis of breast cancer vlogs on YouTube.

258 Background: Vlogs, or “video blogs,” are personally-created experiential videos based on wide-ranging topics, usually posted to YouTube. Many women with breast cancer (BC) document their cancer experiences in YouTube vlogs. These may have the potential to serve as peer-to-peer support and provide community. This study provides a descriptive and content analysis of vlogs by women with BC. Methods: YouTube was searched in incognito mode in 11/2023 using the search terms “breast cancer vlog.” A maximum of 10 videos/creator were included based on viewership and date created.Video characteristics collected included: title, length, number of views, likes, comments, and playlist inclusion. Videos were assessed for sponsorship, presence of explanation and discussion on BC, type of content, and themes. Creator characteristics included age, location, and engagement approaches. Descriptive and content analysis were performed to assess and analyze video content and potential areas where peer-to-peer support may be provided. Results: 90 vlogs by 13 creators were included, all originating from personal accounts. Mean video length, number of views, and number of comments were 21.4 minutes (SD 9.1), 266,780 (SD 534,465), and 1485 (SD 3422), respectively. 38.9% included hashtags. 12.2% included paid sponsorships. Most common filming location was at home (96.7%), followed by the hospital (31.1%), or in the car (21.1%). Home vlogs were most often set in the living room (44.3%), bedroom (33.0%), or kitchen (20.6%). 56.7% included visuals of treatment as well as physical findings. Creators addressed motivation for vlogging in 48.9%; the two most common reasons were wanting to build a community and helping others in a similar situation. In 46.7%, creators explicitly expressed emotion. Most common themes were treatment (85.6%), mental health (81.1%), side effects (72.2%), appearance (63.3%), and family relationships (36.7%). Subthemes included young age, finances, and the importance of online community support. Patient-directed advice was offered in 60.0%, mostly on treatment-related issues. In 56.7%,creators provided explicit treatment definitions. Chemotherapy was discussed in 70.0%; surgery in 57.8%, primarily mastectomy; radiation in 30.0%; general side effects in 71.1%. 24.4% were about a new diagnosis. When mentioned (44.4%), most common creator location was the USA. When mentioned (30.0%), most common age demographic was 20-29 years old. Conclusions: Vlogs by women with BC receive significant levels of engagement. The dedication to building community demonstrated by vlog creators, and the personal nature of their storytelling, advice, and suggestions, may make these vlogs a potential resource for peer-to-peer support.

Unlocking TikTok’s Formula: Video Length, Tags, and Beauty Content Success

With the rapid growth of TikTok in the digital era, beauty influencers have gained significant influence over consumer decisions, particularly through makeup product reviews. TikTok’s short and interactive content style has brought attention to how video characteristics such as length and the number of tags affect engagement metrics like views, likes, and comments. This research explores the impact of these factors using data analysis from a sample of 25 TikTok videos, where the average video length was 2 minutes and 20 seconds, and the top 25% of videos had lengths exceeding 3 minutes and 30 seconds. The findings reveal that longer videos tend to foster deeper engagement by providing more comprehensive reviews, with the top 25% of videos achieving 30% higher engagement than the average. Additionally, a higher number of tags significantly increases video reach. These insights are valuable for influencers and marketers looking to optimize their content strategies, particularly in the beauty industry, where maximizing audience engagement is crucial.

Toward Long Form Audio-Visual Video Understanding

We live in a world filled with never-ending streams of multimodal information. As a more natural recording of the real scenario, long form audio-visual videos (LFAVs) are expected as an important bridge for better exploring and understanding the world. In this article, we propose the multisensory temporal event localization task in long form videos and strive to tackle the associated challenges. To facilitate this study, we first collect a large-scale LFAV dataset with 5,175 videos and an average video length of 210 seconds. Each collected video is elaborately annotated with diversified modality-aware events, in a long-range temporal sequence. We then propose an event-centric framework for localizing multisensory events as well as understanding their relations in long form videos. It includes three phases in different levels: snippet prediction phase to learn snippet features, event extraction phase to extract event-level features, and event interaction phase to study event relations. Experiments demonstrate that the proposed method, utilizing the new LFAV dataset, exhibits considerable effectiveness in localizing multiple modality-aware events within long form videos. We hope that our newly collected dataset and novel approach serve as a cornerstone for furthering research in the realm of LFAV understanding. Project page: https://gewu-lab.github.io/LFAV/ .

Abstract B026: TikTok and #CancerPrevention: A content analysis

Abstract Introduction: TikTok is a widely used social media platform that allows users to post original short-form videos, typically under three minutes long. Of the 121 million TikTok users in the United States, the majority fall in the 18-34 age range. While most videos are classified as “entertainment” users can explore an array of hashtags, including health-related messages. Given its potential to disseminate information on cancer prevention, our project explored the content of #CancerPrevention videos on TikTok. Methods: Using a naïve TikTok account via a web browser, the team extracted the URLs of the top 157 TikTok videos tagged with “CancerPrevention”. We simultaneously collected analytics of the number of likes the videos received, comments, bookmarks, shares, length of video, and upload date. We developed a content codebook that was refined over several sessions to enhance agreement. The team double-coded the top 60 videos that were available and in English. The remaining videos were not double-coded before the URL linking to the video expired, thus limiting our sample to 60. Average coder agreement was 89%. New data: The 60 videos included in the analysis totaled 679,346 likes, 12,567 comments, 180,151 bookmarks, and 69,300 shares. The median length of a video was 53 seconds (range 5 seconds to 7 minutes 24 seconds). The oldest video was posted in March 2021 and the newest in October 2023. Nearly half of the videos appeared to be from health professionals (43.5%), while a quarter were from lay individuals (22.6%). However, most videos were not affiliated with medical organizations, non-profits, or other reputable organizations (93.5%). As the hashtag suggested, most videos targeted a general audience (86.4%) and focused on cancer prevention (68.3%). Half of the videos discussed diet and nutrition as cancer prevention strategies (51.7%), while very few emphasized exercise (13.3%), tobacco use (6.7%), or alcohol use (8.3%). Most videos addressed general cancer prevention (69.5%), with colon cancer being the most frequently specified type (13.6%), followed by breast cancer (5.1%). Very few discussed pharmacology or industry-related topics (6.7%). More than half (56.7%) promoted unconventional cancer prevention strategies, such as avoiding sugar consumption, which is claimed in some videos “to feed cancer cells” and eating specific foods to prevent cancer. Conclusions: Despite uncertainties about its future, TikTok remains a highly popular social media platform among youth and young adults in the U.S., with the ability to rapidly disseminate messages to a wide audience. However, our project revealed that TikTok content often lacks evidence-based information, which can potentially lead to the spread of misinformation. Public health practitioners can use this opportunity to evaluate which messages garner the most engagement and develop research-based content that is relevant and accurate, countering the spread of inaccurate or harmful information.

Persuasion for protection: an analysis of online safety videos on YouTube

PurposePublic service announcements (PSAs) have been shown to be effective instruments that raise awareness, educate society, and change behaviors and attitudes. Many governments and organizations have utilized PSAs on social media to promote online safety among children and youth. However, we have limited understanding of the range of topics that these PSAs address and how they present their content to audiences. This study provides an inventory of the types of online safety topics that current PSAs address and a catalogue of the types of persuasive features employed by PSAs.Design/methodology/approachA content analysis of 220 YouTube PSA videos on online safety was conducted. Various topics under the umbrella of online safety were identified. Guided by the prospect theory and exemplification theory, different persuasive features employed in the PSAs were sought.FindingsThe findings highlight that the primary focus of these PSAs is on online safety behaviors and general instructions on online hygiene. Interestingly, nearly half of the videos employ a neutral frame, while a significant portion provides no evidential support. Additionally, video length was associated with the number of views and likes it gathered but not with the number of comments.Originality/valueThe inventory of PSAs can help researchers, practitioners, and policymakers better understand the type of content being produced and disseminated online as well as identify topics that are either over or under-represented. Further, the catalogue of the types of persuasive features employed by PSAs would be helpful in guiding research, practice, and policymaking in the context of creating effective online safety videos.

The role of news content on Danish broadcasters' streaming services

Amidst the shift from linear TV to streaming, public-service media face the challenge of reconciling commercial competition with their public obligation of informing society. This longitudinal content analysis investigates the curation and platformization of news on the front pages of the video-on-demand services of two Danish broadcasters, DRTV and TV 2 Play. Sampling four days annually from 2020 to 2022, we take a longitudinal approach to assess news curation (i.e., positioning and accessibility on the front page) and news platformization (i.e., video length, hard vs. soft news composition, and prevalence of streaming-first content). We did not find strong evidence of platformization overall. A main difference between the broadcasters was in terms of curation, with DRTV consistently prioritizing the news deck, while TV 2 exhibited a declining trend over time. This study contributes valuable insights into the treatment of news by broadcasters within the evolving context of streaming services.

Analyzing Quality of YouTube Videos about Premature Ovarian Failure in the Past Decade

Background: To determine the quality of YouTube videos about premature ovarian failure (POF), and variations in quality of professional YouTube videos about POF. Methods: The selected terms including ‘POF’, ‘premature ovarian insufficiency’, ‘POF, infertility’, ‘POF, symptoms’, ‘POF, diagnosis’, and ‘POF treatment’ were searched on YouTube. Totally, 100 videos each uploaded by professional and non-professional sources were included. Characteristics of videos were noted and quality of YouTube videos were analyzed according to Global Quality Score (GQS) and modified DISCERN scale. The two groups were compared in terms of video characteristics, GQS, and modified DISCERN score. Videos uploaded by professional sources were categorized into two different groups from the first 5 years and the last 5 years, and compared. Results: The mean number of views was 2961 for professional videos and 2003 for non-professional videos (p= 0.006), and the mean duration of videos was 10 minutes for professional videos and 6 minutes for non-professional videos (p= 0.001). When professional videos in the last 10 years were evaluated, number of views and ‘likes’ were significantly higher in favor of professional videos between 2014-2018 (p= 0.033 vs. p= 0.037). Video duration was significantly shortened for videos between 2019-2023 (p= 0.002). Patients as the target audience dominated videos prepared in the last 5 years (p= 0.001). Professional videos had significantly higher GQS and modified DISCERN score (p= 0.001 for each parameter). Moreover, GQS and modified DISCERN scores of professional videos increased significantly in the last 5 years (p= 0.001 vs. p= 0.023). Conclusions: Professional YouTube videos about POF had significantly higher quality and ‘like’ numbers, and the quality of professional YouTube videos about POF significantly increased in the last five years. The proportion of professional videos about POF being prepared for patients increased significantly in the last 5 years, but video length of professional videos significantly decreased.
