Directly Observing and Characterizing Adolescents' Self-Generated Social Media Posts: Protocol for Creation and Implementation of a Cyberethnography Informed Codebook.
Article in JMIR research protocols, 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
Background: Adolescent social media research has primarily focused on frequency of platform use and self-report measures. There has been limited focus on the self-generated content posted by adolescents and how this might relate to their well-being. Objective: This study describes a researcher-observed codebook for characterizing adolescents' self-generated content in a longitudinal sample. Methods: Participants in the study provided informed assent (and parental informed consent) for researchers to follow them and passively observe their self-generated content on Instagram (Meta Platforms), TikTok (ByteDance Ltd), Facebook (Meta Platforms), and X (formerly known as Twitter; X Corp). Guided by Bronfenbrenner's social ecological biopsychosocial model, the research team created a codebook incorporating prior cyberethnographic observation of self-generated social media content. After codebook refinement, coders (research staff and student research assistants) were trained through multiple rounds of test coding, and the codebook was applied to participant data with periodic quality control measures to ensure interrater reliability. Results: This study was funded in early 2023 and began data collection in March 2023 and will conclude in 2027. So far, the interrater reliability agreement scores (AC1) between coders have shown strong interrater reliability. For Year 1, scores were Facebook 0.89, Instagram 0.89, TikTok 0.88, X 0.87, and combined 0.88; for Year 2, Facebook 0.95, Instagram 0.96, TikTok 0.96, X 0.96, and combined 0.96. This project provides replicable guidance to categorize social media data from adolescent participants using human coders who can contextualize content through longitudinal observation. The method that our team chose and followed paved the way for many strengths to be recognized as well as lessons learned by our team that allowed for adaptation and growth to occur while this study has been ongoing. Conclusions: Cyberethnography, the chosen method for this research protocol, has allowed this research project to collect self-generated content for adolescent social media in a comprehensive manner. Thus, allowing our team to be able to cross-analyze this data with the well-being data that are being collected under the grander project for patterns. Sharing our protocol through this paper will also allow other researchers to draw from our methodology for future projects to aid in social media and adolescent understanding.
