Adolescent Digital Self-Harm Over Time: Prevalence and Perspectives

Digital self-harm, the anonymous online posting, sending, or otherwise sharing of hurtful content about oneself, has not received the same amount of scholarly scrutiny as other forms of self-directed abuse. In the current paper, we analyze three independent national surveys of U.S. teens (aged 13–17, M = 14.96) in repeat cross-sectional studies conducted in 2016 (N = 4,742), 2019 (N = 4,250), and 2021 (N = 2,546) to assess the prevalence of two measures of digital self-harm. We examine demographic differences within each sample (gender, race, and sexual orientation), whether experience with cyberbullying was associated with these behaviors, and changes over time. Overall, the prevalence of digital self-harm has been increasing over time, and changes in demographic influences were observed. Implications for identifying, preventing, and responding to digital self-harm are discussed.
