New study links social media use to increased cyberbullying risk for adolescent girls

A longitudinal study published in The Lancet Child & Adolescent Health on 16 September 2024 found that adolescent girls who spend more than three hours daily on social media platforms face nearly double the risk of experiencing cyberbullying compared to those with lower usage, with researchers tracking 5,000 participants aged 12 to 16 across four years in the United Kingdom. The study identified direct messaging and group chats as the primary environments where bullying occurs, and noted that sustained harassment campaigns, rather than isolated incidents, were responsible for the most severe mental health impacts including depression and self-harm. The authors called for platform design changes and improved detection tools to identify and interrupt bullying behaviour before it escalates.

Identifying a pattern of sustained targeting is the operational challenge that existing reporting mechanisms, which rely on a victim or bystander to flag an incident after it has occurred, fail to address. Guardii's anti-cyberbullying detection module monitors direct-message exchanges for the linguistic and behavioural markers of escalation, repetition and coordination, surfaces a child being targeted to a parent or school in real time, and enables intervention while the harm is still unfolding rather than after the psychological damage is done, translating the study's evidence base into an actionable safeguarding response.
