Item Facebook and suicidal behaviour: user experiences of suicide notes, live-streaming, grieving and preventive strategies-a scoping review(Basel, 2022) Shoib, S.; Chandradasa, M.; Nahidi, M.; Amanda, T.W.; Khan, S.; Saeed, F.; Swed, S.; Mazza, M.; Di nicola, M.; Martinotti, G.; Di giannantonio, M.; Armiya'u, A.Y.; De berardis, D.Background: Facebook represents a new dimension for global information sharing. Suicidal behaviours and attempts are increasingly reported on Facebook. This scoping review explores the various aspects of suicidal behaviours associated with Facebook, discussing the challenges and preventive measures. Methods: PubMed, Google Scholar, and Scopus were searched for related articles published in English up to October 2021, using different combinations of "Facebook" and "suicide". A group of experts comprising consultant psychiatrists screened the records and read the full-text articles to extract relevant data. Twenty-eight articles were chosen as relevant and included in the review under four selected themes. Results: Facebook impacts on suicidal behaviours in different aspects. Announcing suicides through sharing notes or personal information may lead to the prediction of suicide but be harmful to the online audience. Live-streaming videos of suicide is another aspect that questions Facebook's ability to monitor shared contents that can negatively affect the audience. A positive impact is helping bereaved families to share feelings and seek support online, commemorating the lost person by sharing their photos. Moreover, it can provide real-world details of everyday user behaviours, which help predict suicide risk, primarily through novel machine-learning techniques, and provide early warning and valuable help to prevent it. It can also provide a timeline of the user's activities and state of mind before suicide. Conclusions: Social media can detect suicidal tendencies, support those seeking help, comfort family and friends with their grief, and provide insights via timelining the users' activities leading to their suicide. One of the limitations was the lack of quantitative studies evaluating preventative efforts on Facebook. The creators' commitment and the users' social responsibility will be required to create a mentally healthy Facebook environment.Item Student usage of open educational resources and social media at a Sri Lanka Medical School(BioMed Central, London, 2022) Hettige, S.; Dasanayaka, E.; Ediriweera, D.S.Background: The use of Open Educational Resources (OER) and Social Media (SM) for academic information seeking is common among undergraduates nowadays. There is limited data on OER and SM use for education in Sri Lanka. This study was aimed at evaluating the OER and SM use for education among the medical students at the Faculty of Medicine, University of Kelaniya, Sri Lanka. Methods: A cross-sectional study was conducted at the Faculty of Medicine, University of Kelaniya. Stratified random sampling was used to select students from the first year to the final year. A self-administrated questionnaire was used to collect data. Results: The study included 257 responses (response rate: 89.5%), of which 185 (72.0%) were females. The OER and SM use for educational purposes at least once a month among students was 96.1% (95%CI: 93.7-98.5%) and 88.3% (95%CI: 84.4-92.3%) respectively. There was no gender difference in OER and SM use. The main reasons for accessing OER were the availability of information at any time (36.1%) and ease of information access (31.5%). Wiki sites (84.4%) and Facebook (79.8%) were the highest accessed OER and SM platforms. The majority of students were in view that the information on wiki sites (51.4%) and results of general non-specific web searches (56.0%) were reliable. Only 33.9% of students searched information from educational and government-related sources and 18.7% had accessed e-journals. Through SM, 79.0% joined educational groups and 77.0% followed the medical-related sites, pages and people. More than one-third of students (35.8%) could not find academic information from SM due to the information overload and 31.1% mentioned that SM distracted their education. Conclusion: The majority of the students used OER and SM for education; however, only a minority accessed reliable information. Students accepted information available in wiki sites and general non-specific web searchers without considering the credibility of sources. The majority of the students did not refer to e-journals. Distractions to academic work and the difficulty to access accurate information were major concerns of using SM. This study highlights the importance of improving information literacy among medical students.Item Violence seen on Facebook and YouTube videos: a qualitative study(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2021) Harshani, P.; Jayananda, C.; Hapuarachchi, N.; Harshana, U.; Kularathna, H.; Athauda, L.Introduction: Social media is popular specially among young adults in Sri Lanka. In the recent past, violent and graphic content have been seen circulating on social media. Objectives: To describe violence published on social media (Facebook and YouTube) in the last three months of 2019. Methods: This was an observational study. Facebook and YouTube were searched for videos depicting physical, sexual, emotional violence and verbal abuse using Sinhala and English search terms (shoot*, bomb* etc.). Duplicate videos were removed and analysed for their content (types of violence, reactions of viewers). Two researchers individually interpreted the videos for their content. Results: The analysis included 94 videos including 27 from Facebook and 67 from YouTube. YouTube had 28 promoting and 26 educational type violent videos while Facebook had 15 and 6 per each type, respectively. Physical violence (YouTube=52; Facebook=21) was the most common type of violence seen on both media. Likes (n=5326), haha (n=805) and sad (n=286) were the most prominent reactions observed on Facebook. Videos on both Facebook and YouTube represented violence as newsworthy, entertaining items and depicted of misuse of power or law. Violence was also displayed by v-loggers as experiments and used for publicity and promotion of social media channels. Those who witnessed violence reacted against it only if the recipient was a female. Conclusions: During the 3-month period observed, various types of violent content were shared on Facebook and YouTube. Physical violence was prominently seen on both media. Violence was used to increase views and potentially as marketing tools for commercial interests.
