Exploring YouTube Comments to Understand Public Sentiment on COVID-19 Vaccines through Deep Learning-based Sentiment Analysis

COVID-19 was first found in China in 2019. Since then, it has quickly spread around the world, which has led to a lot of news stories and social media posts about the pandemic. YouTube, a popular video-sharing website, has become a valuable source of information on COVID-19 and other topics. However, it can be difficult to extract useful insights from the vast array of user comments that accompany these videos. One potential method for understanding public sentiment is to use sentiment analysis, which involves classifying text as positive, negative, or neutral. In this study, the dataset of over 44,000 YouTube comments related to COVID-19 vaccines was used, which was filtered to a total of 16,073 comments for analysis. The data was cleaned and organised using NeatText and then processed using GloVe word embedding, a technique for establishing statistical relationships between words. Based on the experiment, the performances of three different types of deep learning techniques: recurrent neural networks (RNN), gated recurrent units (GRU) and long short-term memory (LSTM) are compared in accurately classifying the sentiment of the comments. The study found that the GRU had the highest accuracy of 80.19%, followed by the LSTM with 79.00% accuracy, and the RNN with 67.15% accuracy.

Activist Musicology and Informal Multimedia Archives: The Case of YouTube Channel “Serbian Composers”

The YouTube channel “Serbian Composers” was founded in 2012 by four musicology students from Belgrade. As the first page dedicated to both art music and applied music of Serbian composers on this popular video-sharing website, over the past 11 years this channel has shown itself to be an excellent platform for the promotion, multi-media archiving, research, digitalization, and preservation of Serbian music. The founders of the channel—nowadays active researchers in the field—recognized the potential of YouTube for applied musicological work and worked diligently on making this channel the most reliable online source for anyone interested in Serbian composers and their works. In this article, we elaborate on what working on this channel throughout the years has entailed. We cover the realities of both the social media and internet presence of one such endeavor and situate the research in the domain of seeing YouTube as an informal multimedia archive. We also discuss the ongoing processes of collecting music and data, digitalization and preservation, selection and categorization, and the presentation of material on YouTube and other relevant social media platforms.

The Emotional Impact of Educational Productivity Videos on YouTube: A Global, Cross-Sectional Survey.

Introduction YouTube is the most popular video-sharing website, and many students use it as a resource to find educational content. One type of video category is "productivity," in which the creator teaches viewers how to lead a more productive lifestyle by sharing ways to maximize studying, reshape daily habits, or set achievable goals. Little research has been conducted on whether these videos actually promote positive or negative feelings among viewers. Methods A survey was created through Qualtrics and shared through YouTube and Instagram. The survey asked about exposure to productivity videos and also asked individuals to share their experiences with consuming productivity-related educational content on YouTube. Survey items asked students to rate the helpfulness of these videos and share their feelings about the content. Respondents were asked to share whether YouTube videos on productivity made them feel anxious, motivated, inspired, neutral/indifferent, or inadequate. Participants were also asked to rate how helpful they found productivity videos on YouTube (1-10, with 10 being most helpful). The survey included free response sections to assess viewers' perceptions and attitudes toward productivity videos. Results The cross-sectional survey amassed 595 responses across 60 countries, with 364 responses coming from individuals within the United States. Of the respondents, 397 of the respondents were female, 177 were male, and 21 preferred not to say or identified as non-binary. The average age of participants was 22 years; 79 were in high school, 174 were in college, 223 were in medical school, and the remainder identified as "other" (graduate school, gap year, etc.). Of the 595 completed responses, 494 reported watching videos on YouTube related to improving productivity; when asked how these videos made them feel, 127 participants answered "anxious," 357 answered "motivated," 308 answered "inspired," 95 answered "neutral/indifferent," and 97 answered "inadequate." When rating how helpful they found these videos (1-10), an average score of 6.8 was recorded. Conclusion Most viewers feel motivated or inspired by productivity videos on YouTube. Based on the free responses provided by survey participants, productivity videos can be made more effective by showing more relatable routines and demonstrating what viewers should do when goals are not met.

Self-removal of long-acting reversible contraception: A content analysis of YouTube videos

ObjectiveTo explore publicly available information about the self-removal of long-acting reversible contraception (LARC) on a popular video-sharing website. Study designWe conducted a comprehensive keyword search of YouTube videos related to self-removal of LARC—namely intrauterine devices and implants. We analyzed video content to explore demographic characteristics, method and duration of LARC use, and motivations and experiences of self-removal. ResultsOur keyword search identified 58 videos that met the criteria for inclusion, including 48 videos that featured individuals who removed an intrauterine device and 10 who removed an implant. Collectively, videos had over 4 million views. We identified most video creators as white (53%), 31% as Black, and 14% as Latinx. Users were motivated to remove their own device by both preferences and barriers to formal care. Most individuals in our sample (n = 56/58) successfully removed their device and described their experience in positive terms related to the ease of removal. Reasons for LARC discontinuation included negative side effects, fear of potential side effects, and desire for pregnancy. ConclusionThis study builds upon prior research by describing publicly available information about LARC self-removal. The over representation of Black women in our sample may reflect a higher prevalence of LARC self-removal among this population. Positive experiences of self-removal and high levels of viewer engagement with online videos suggest a need for provider counseling on LARC removal at the time of insertion. ImplicationsPrior to LARC insertion, patients should be made aware of any financial requirements for discontinuation. Provider counseling for self-removal at the time of insertion will likely minimize health risks and affirm patient reproductive autonomy.

Consulting “Dr. YouTube”: an objective evaluation of hypospadias videos on a popular video-sharing website

Parents who make decisions about hypospadias repair for their child may seek information from online platforms such as YouTube. The purpose of this study is to evaluate the health literacy demand of hypospadias videos on YouTube using the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-A/V). We performed a YouTube search using the term "hypospadias," limiting results to the first 100 videos. We excluded videos that were <1min or >20min and videos that were not in English or did not include subtitles. Two evaluators independently examined videos and determined PEMAT-A/V scores for understandability and actionability (i.e., ability to identify actions the viewer can take). Videos with scores >70% are understandable or actionable. The inter-rater reliability (kappa) and intraclass correlation coefficient (ICC) of PEMAT scores were calculated. Bivariate and multivariable linear regression models assessed the association of video characteristics with respective scores. Of the 100 videos that were identified on YouTube, 47 (47%) were excluded leaving 53 for analysis: 14 were >20min, 14 were <1min, 9 had no audio or subtitles, 7 were not in English, 1 was a duplicate, 1 was unrelated to hypospadias, and 1 was deleted at the time of data analysis. Three (5.6%) were understandable (mean score 54.5%, standard deviation (SD) 14.9) and eight (15.1%) were actionable (mean score 21.8%, SD 16.6) (Extended Summary Figure). Kappa values ranged from 0.4 to 1. The ICC's were 0.55 and 0.33 for understandability and actionability, respectively. In the bivariate analysis, mean understandability scores were significantly higher for English language videos (p=0.04), videos with animation (p=0.002), and those produced by industry (p=0.02). In the multivariable analysis, mean understandability scores were significantly higher for "expert testimonial" or "other" video types after adjusting for graphics type and overall tone (p=0.04). Mean understandability scores were also significantly higher for videos with animation after adjusting for video type and overall tone (p=0.01). Mean actionability scores were significantly higher for videos with a negative tone (p=0.01). The vast majority of hypospadias-related YouTube content is not appropriate for users with low health literacy although certain types of videos, such those with animation and expert testimonials, scored higher on understandability than other types. Due to the lack of sufficient online informational content regarding hypospadias, we plan to engage parents of sons with hypospadias in the development of high-quality patient educational materials about hypospadias.

YouTube as an informational source for brachial plexus blocks: evaluation of content and educational value

Background and objectivesYouTube, the most popular video-sharing website, contains a significant number of medical videos including brachial plexus nerve blocks. Despite the widespread use of this platform as a medical information source, there is no regulation for the quality or content of the videos. The goals of this study are to evaluate the content of material on YouTube relevant to performance of brachial plexus nerve blocks and its quality as a visual digital information source. MethodsThe YouTube search was performed using keywords associated with brachial plexus nerve blocks and the final 86 videos out of 374 were included in the watch list. The assessors scored the videos separately according to the Questionnaires. Questionnaire-1 (Q1) was prepared according to the ASRA guidelines/Miller's Anesthesia as a reference text book, and Questionnaire-2 (Q2) was formulated using a modification of the criteria in Evaluation of Video Media Guidelines. Results72 ultrasound-guided and 14 nerve-stimulator guided block videos were evaluated. In Q1, for ultrasound-guided videos, the least scores were for Q1–5 (1.38) regarding the complications, and the greatest scores were for Q1–13 (3.30) regarding the sono-anatomic image. In videos with nerve stimulator, the lowest and the highest scores were given for Q1–7 (1.64) regarding the equipment and Q1–12 (3.60) regarding the explanation of muscle twitches respectively. In Q2, 65.3% of ultrasound-guided and 42.8% of blocks with nerve-stimulator had worse than satisfactory scores. ConclusionsThe majority of the videos examined for this study lack the comprehensive approach necessary to safely guide someone seeking information about brachial plexus nerve blocks.

Rolling and scrolling: The portrayal of marijuana cigars (blunts) on YouTube

ABSTRACTBackground: Blunts are partially or fully hollowed-out cigars or cigarillos that are filled with marijuana. Despite the high prevalence of blunt use, very few studies assess this specific method of cannabis administration. YouTube, a popular video-sharing website, has the potential to provide insights into blunt use. Methods: The purpose of this study was to examine the content of YouTube videos that discuss blunts. A sample of 41 videos was coded for content. Results: The 41 videos had a total of 27,579,636 views. Most of the individuals in the videos were male (85%) and many appeared to be White (80%) and under the age of 25 (46%). Only 34% of the videos had an age restriction. The majority of messages in the videos promoted blunt use (93%) and showed at least one person rolling (76%) and/or smoking (66%) a blunt. The videos mainly consisted of introductions to blunt use (76%) and tips and personal experiences with blunt use (73%). Conclusions: YouTube videos on blunt use are readily available and primarily promote the use of blunts. Future research should continue to monitor YouTube content and develop videos on social media platforms that inform consumers of the health effects associated with blunt use.

A Thematic Analysis of Spectator Violence at Sporting Events in North America

ABSTRACTThis study examines aggravating and mitigating circumstances surrounding spectator fights at stadiums and arenas in North America. Data were collected utilizing a sample of video recordings posted to a popular video-sharing website. A thematic analysis of the data reveals several influences including the role of team allegiances, alcohol use, security presence, and bystander behavior. Potential preventive and reactive interventions to discourage violence in this setting are discussed and evaluated.

Educational Quality of YouTube Videos in Thumb Exercises for Carpometacarpal Osteoarthritis: A Search on Current Practice.

Conservative treatments are commonly performed therapeutic interventions for the management of carpometacarpal (CMC) joint osteoarthritis (OA). Physical and occupational therapies are starting to use video-based online content as both a patient teaching tool and a source for treatment techniques. YouTube is a popular video-sharing website that can be accessed easily. The purpose of this study was to analyze the quality of content and potential sources of bias in videos available on YouTube pertaining to thumb exercises for CMC OA. The YouTube video database was systematically searched using the search term thumb osteoarthritis and exercises from its inception to March 10, 2017. Authors independently selected videos, conducted quality assessment, and extracted results. A total of 832 videos were found using the keywords. Of these, 10 videos clearly demonstrated therapeutic exercise for the management of CMC OA. In addition, the top-ranked video found by performing a search of "views" was a video with more than 121 863 views uploaded in 2015 that lasted 12.33 minutes and scored only 2 points on the Global Score for Educational Value rating scale. Most of the videos viewed that described conservative interventions for CMC OA management have a low level of evidence to support their use. Although patients and novice hand therapists are using YouTube and other online resources, videos that are produced by expert hand therapists are scarce.

“It Takes Longer, but When It Hits You It Hits You!”: Videos About Marijuana Edibles on YouTube

ABSTRACTBackground: Interest in marijuana edibles has increased as perceptions of harm from marijuana have decreased. Media and peer influences impact youth substance use, and YouTube is the most popular video-sharing website. No studies have examined the content and accessibility of YouTube videos related to marijuana edibles. Objectives: To describe the messages conveyed to viewers in YouTube videos about edibles and determine their accessibility to youth. Methods: On June 12, 2015, we searched YouTube for videos about marijuana/cannabis/weed edibles. A total of 51 videos were coded for presence of an age restriction, purpose(s) of the videos, consumption of edibles during the video, effects, and safety concerns. Results: Total views across all 51 videos were >9 million. Only 14% (7/51) were restricted to viewers over the age of 18 years. Over half (27/51, 53%) were informative videos, most (20/27, 74%) teaching how to make edibles, and 37% (19/51) were entertaining videos. Someone consumed an edible in 31% (16/51) of the videos, and the type of high was mentioned in 51% (26/51) of the videos, including delayed (18/26, 69%) or intense high (13/26, 50%). Fifty-five percent (28/51) mentioned delta-9-tetrahydrocannabinol potency or dosage. Only 10 of these (36%) presented this information specifically as a warning to prevent adverse effects. Conclusions/Importance: Edibles-related videos are easily found on YouTube, often instructing how to bake your own edibles and lacking information needed for safe consumption, and most are not age-restricted. Videos showing how to make edibles or presenting edibles use in an entertaining way that could influence youth to initiate use.

Schizophrenia on YouTube.

YouTube ( www.youtube.com ) is the most popular video-sharing Web site on the Internet and is used by medical students as a source of information regarding mental health conditions, including schizophrenia. The accuracy and educational utility of schizophrenia presentations on YouTube are unknown. The purpose of this study was to analyze the accuracy of depictions of psychosis in the context of a diagnosis of schizophrenia (referred to in this article as "acute schizophrenia") on YouTube and to assess the utility of these videos as educational tools for teaching medical students to recognize the clinical features of acute schizophrenia. YouTube was searched for videos purporting to show acute schizophrenia. Eligible videos were independently rated by two consultant psychiatrists on two separate occasions 22 days apart for diagnostic accuracy, psychopathology, and educational utility. Videos (N=4,200) were assessed against predefined inclusion and exclusion criteria. The majority were not eligible for further analysis, mostly because they did not claim to show a patient with schizophrenia (74%) or contained duplicated content (11%). Of 35 videos that met the eligibility and adequacy criteria, only 12 accurately depicted acute schizophrenia. Accurate videos were characterized by persecutory delusions (83%), inappropriate affect (75%), and negative symptoms (83%). Despite the fact that 83% of accurate videos were deemed to have good educational utility compared with 15% of inaccurate videos, accurate and inaccurate videos had similar view counts (290,048 versus 186,124). Schizophrenia presentations on YouTube offer a distorted picture of the condition.

'There is a dependent patient in our home': designing and disseminating a family caregiving program through YouTube.

Family members play a major role in providing care for older people and long-term dependent patients, especially in developing countries where there is a lack of specialized nursing homes and specialized home-visiting programs. Family members are rarely provided with sufficient information or training to provide home care for their dependent relatives. There are inadequate home caregiving educational resources directed to Arabic-speaking caregivers, either in written or in audiovisual presentations. The aims of the present study were (i) to present the process of designing a caregiving educational program entitled 'there is a dependent patient in our home', with an intention to be culturally and linguistically appropriate for a specific Arab-speaking population, and (ii) to present the experience of disseminating the program through YouTube, to be accessible for a wide range of caregivers. The program was a product of a process involving seven phases, starting with a review of the literature and ending with disseminating 17 short 'caregiving' videos on YouTube, the most popular video-sharing website. The program presented necessary skills, instructions, and information that enabled caregivers to provide safe and competent daily caring activities for their functionally dependent relative or older adults at home. The program was registered in the Jordan National Library. After 2 months of broadcasting it on YouTube, the number of views exceeded 6800. Many constructive comments were received from caregivers. Language, simplicity, and attractiveness of the program were judged as the areas of satisfaction by the viewers, whereas lack of a few topics such as verbal communication with patients and dealing with daily caregivers' burden and stressors were the main reasons of dissatisfaction. This program was an endeavor to provide the Arabic library with a home caregiving resource. Adequate advertisement of the program would encourage health providers to search for and use the currently available social media as means of delivering educational services to family caregivers.

Educational Quality of YouTube Videos on Knee Arthrocentesis

Knee arthrocentesis is a commonly performed diagnostic and therapeutic procedure in rheumatology and orthopedic surgery. Classic teaching of arthrocentesis skills relies on hands-on practice under supervision. Video-based online teaching is an increasingly utilized educational tool in higher and clinical education. YouTube is a popular video-sharing Web site that can be accessed as a teaching source. The objective of this study was to assess the educational value of YouTube videos on knee arthrocentesis posted by health professionals and institutions during the period from 2008 to 2012. The YouTube video database was systematically searched using 5 search terms related to knee arthrocentesis. Two independent clinical reviewers assessed videos for procedural technique and educational value using a 5-point global score, ranging from 1 = poor quality to 5 = excellent educational quality. As validated international guidelines are lacking, we used the guidelines of the Swiss Society of Rheumatology as criterion standard for the procedure. Of more than thousand findings, 13 videos met the inclusion criteria. Of those, 2 contained additional animated video material: one was purely animated, and one was a check list. The average length was 3.31 ± 2.28 minutes. The most popular video had 1388 hits per month. Our mean global score for educational value was 3.1 ± 1.0. Eight videos (62 %) were considered useful for teaching purposes. Use of a "no-touch" procedure, meaning that once disinfected the skin remains untouched before needle penetration, was present in all videos. Six videos (46%) demonstrated full sterile conditions. There was no clear preference of a medial (n = 8) versus lateral (n = 5) approach. A discreet number of YouTube videos on knee arthrocentesis appeared to be suitable for application in a Web-based format for medical students, fellows, and residents. The low-average mean global score for overall educational value suggests an improvement of future video-based instructional materials on YouTube would be necessary before regular use for teaching could be recommended.

Are YouTube seizure videos misleading? Neurologists do not always agree

The internet has become the first stop for the public and patients to seek health-related information. Video-sharing websites are particularly important sources of information for those seeking answers about seizures and epilepsy. Because of the widespread popularity of YouTube, we sought to explore whether a seizure diagnosis and classification could reliably be applied. All videos related to “seizures” were reviewed, and irrelevant videos were excluded. The remaining 162 nonduplicate videos were analyzed by 4 independent pediatric neurologists who classified the events as epilepsy seizures, nonepileptic seizures, or indeterminate. Videos designated as epilepsy seizures were then classified into focal, generalized, or unclassified. At least 3 of the 4 reviewers agreed that 35% of the videos showed that the events were “epilepsy seizures”, at least 3 of the 4 reviewers agreed that 28% of the videos demonstrated that the events were “nonepileptic seizures”, and there was good agreement that 7% of the videos showed that the event was “indeterminate”. Overall, interrater agreement was moderate at k=0.57 for epilepsy seizures and k=0.43 for nonepileptic seizures. For seizure classification, reviewer agreement was greatest for “generalized seizures” (k=0.45) and intermediate for “focal seizures” (k=0.27), and there was no agreement for unclassified events (k=0.026, p=0.2). Overall, neurology reviewer agreement suggests that only approximately one-third of the videos designated as “seizures” on the most popular video-sharing website, YouTube, definitely depict a seizure. Caution should be exercised in the use of such online video media for accessing educational or self-diagnosis aids for seizures.

An Examination of the Scope and Nature of Non-Suicidal Self-Injury Online Activities: Implications for School Mental Health Professionals

Non-suicidal self-injury (NSSI) is an increasing concern among mental health professionals working with youth. The presence of NSSI on the Internet has grown considerably over the last decade. Studies investigating NSSI Internet activities suggest a strong adolescent audience. Research suggests that the general Internet experiences for youth who are currently engaging in or have a history of NSSI may be different than that of youth who do not engage in the behavior. The present study is the first to simultaneously examine the scope and nature of NSSI content across informational/interactive websites, social networking websites, and the popular video-sharing website YouTube, in order to provide mental health practitioners with a multifaceted description of online content related to NSSI. Results suggest that peer driven, informal websites have a variety of triggering content and are accessed more often than professionally driven websites. NSSI is strongly represented among social networking websites, and YouTube, evidenced by large group memberships and video view counts. Based on these findings, a series of practical implications and recommendations are provided to assist mental health practitioners in assessing online NSSI-related activities among youth who are currently engaging in or have a history of NSSI, with implications for intervention and recovery.

Salvia divinorum: Effects and use among YouTube users

Salvia divinorum (salvia) is an intense, short-acting hallucinogenic plant gaining popularity among adolescents in the United States. There has been little scientific documentation of salvia's effects. The popular video-sharing website YouTube has received literally thousands of video-posts of people using salvia. The objective of this study was to assess the effects of salvia use through systematic observations of YouTube videos. A sample of salvia videos was obtained using the search term "salvia." The videos were further screened and only videos that captured the entire drug "trip" without video edits were included in the analyses described here (n=34). Three trained research assistants independently watched the videos and rated their observations on 42 effects in 30-s intervals. Onset of symptoms was quick (often less than 30s) and tended to dissipate within 8min. Further, there was a relationship between salvia dose and effect duration. Since salvia's effects on humans are largely undocumented, this study provides the look at users in a non-laboratory environment (e.g. self-taped videos) exhibiting impairments and behaviors consistent with this powerful hallucinogen. Also, this study demonstrates the feasibility and shortcomings of using YouTube videos to assess emerging drugs and drug effects.
