Adolescents' Experiences of Online Harms by Platform.
Article in JAMA pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Importance: Concerns about the risks adolescents face online are rising, and existing research on online harms rarely examines platform-level differences. Objective: To estimate the prevalence of negative experiences reported by US adolescents online, offline, and across 20 different online platforms using a national survey. Design, Setting, and Participants: This was a cross-sectional, nationally representative, pilot survey of US adolescents aged 13 to 17 years conducted from February to December 2025 through the probability-based Understanding America Study panel. Self-reported use and negative experiences on 20 online platforms (eg, Facebook, Instagram, Snapchat, TikTok, and YouTube) were assessed. Exposures: Self-reported use of 20 online communication platforms (eg, Facebook, Instagram, TikTok, Snapchat, and YouTube) in the past 4 weeks. Main Outcomes and Measures: Prevalence of adolescents' reporting experiencing major risks and harms online, offline, and for each of 20 online platforms in the last 4 weeks. Harms include harassment, sexual solicitation, exposure to violent content, and technology-related sleep disruption. Survey-weighted logistic regression examined demographic associations. Results: The weighted sample included 472 adolescents (mean [SE] age 14.9 [0.1] years; 46.8% female) from 47 states. Across online and offline contexts, 44.7% witnessed harassment and 29.8% reported experiencing it directly in the past 4 weeks. Online exposure exceeded offline exposure for several harms, including reported exposure to violent imagery (10.7% vs 1.6%), unwanted sexual images (13.4% vs 2.0%), and content encouraging self-harm (9.7% vs 5.2%), while direct harassment was reported at similar rates offline and online (18.5% vs 16.4%). More than half (51.5%) self-reported sleep disruption due to technology use. Prevalence varied by platform. Conclusions and Relevance: The findings suggest that negative online experiences are commonly reported by US adolescents and vary across platforms and subgroups of adolescents. Measuring the prevalence of negative online experiences is feasible and analogous to public health risk monitoring frameworks.
