An Exploration of the Negative Impact of Social Media and Strategies for Intervention

Abstract

Social media platforms are vital in connecting individuals globally. However, to thrive, these platforms must prioritize user and content creator satisfaction and engagement, which are key to their success. This highlights the importance of designing social media platforms with a user-centric approach that considers not only the technical aspects of interaction but also the psychological and emotional effects on the user. For instance, the sudden deletion of user-generated content without any explanation or warning can elicit negative emotions and frustration, while exposure to appealing digital food cues can indirectly affect users’ well-being and fuel the obesity epidemic. This thesis explores the impact of social media on individuals’ physical and emotional states and evaluates possible interventions aimed at mitigating its potential risks. It presents a comprehensive, large- scale examination of videos that have been removed by YouTube or deleted by their uploaders. It develops and assesses three prediction models that can predict which videos will be removed at three stages of their lifespan. Additionally, it presents a large-scale, mixed-method approach to quantify the prevalence of food cues on Snapchat in three countries with different cultural backgrounds (Saudi Arabia, the United States, and France). It also measures the impact of exposure to Snapchat food content on appetite and whether it may inadvertently exacerbate cravings. Finally, it sheds light on Snapchat users’ perceptions of a proposed intervention design idea, allowing them to customize their feed and hide food content to reduce exposure to it. The outcomes of this thesis offer valuable insights and recommendations for how social media platforms can be improved to promote a healthier and more positive user experience.
