- PublicationOpen AccessVisualización e interpretación de las interacciones en los mensajes de autolesiones no suicidas en Twitter(Universitat Autònoma de Barcelona, 2023-04-11) Atauri-Mezquida, David; Nicolás-Ojeda, Miguel Ángel; Blanco-Ruiz, Marian; Martínez-Pastor, Esther; ComunicaciónNon-suicidal self-harm (NSA) is a growing phenomenon, according to many organisations such as UNICEF, and it affects young people to a large extent. Our aim is to define a strategy to analyse the posts made on Twitter by young people who self-harm, whether there are different types of users and how the community reacts. We have downloaded the messages tagged with the hashtags #selfharm, #shtwt or #ouchietwt from 21 October to 21 November 2022, obtaining a sample of 1951 messages. We then retrieved likes, retweets and replies by grouping all messages into conversations. Finally, we retrieve information from the profiles of the users involved. For each tag we graphically represent the network structure formed by the interactions, being the users the nodes of the network and the interactions (likes, replies or retweets) the lines that join the nodes. It can be clearly seen how likes are the most frequent interaction, and which profiles generate the most responses and support. A manual review of the messages with the most support reveals that they are almost all messages with explicit photos of open injuries. The responses they elicit are likes, congratulations and messages of admiration. From the data obtained we conclude that Twitter tags such as #shtwt and #ouchietwt reinforce self-harming behaviours, mainly by gaining community recognition through likes. Interactions between self-harmers and health professionals on Twitter are minimal.
