Cyberbullying Victims Experience 90% Depression Rate and 87% Anxiety Rate, Systematic Review Finds

A systematic literature review published in March 2026 in the peer-reviewed journal Children found that cyberbullying victims experience significantly higher rates of depression at 90 percent and anxiety at 87 percent compared to aggressors, with effects often being more severe and prolonged than traditional bullying due to anonymity and lack of safe spaces. The review, conducted by the SONEV Research Group at the Catholic University of Valencia, synthesized evidence on the relationship between cyberbullying and adolescent mental health, confirming that the psychological harm from online abuse is both measurable and persistent.

The research quantifies the mental-health burden that follows sustained online abuse, yet diagnosis occurs after harm has already been inflicted. Guardii's anti-cyberbullying detection module identifies sustained targeting, escalation and coercion in direct-message conversations as they unfold, surfacing a child in acute distress to a parent or school before the harm reaches the threshold documented in the systematic review. Operating in real time across Instagram, Snapchat, Discord, Roblox and other platforms, the system detects hostile contact patterns rather than reading every message, flagging a conversation when it exhibits the markers of persistent harassment. A world-leading AI online-safety platform, Guardii reports the shape and seriousness of a conversation to the appropriate authority, enabling intervention at the point of crisis and reducing the likelihood that a child will experience the depression and anxiety rates confirmed by the research.
