Cyberbullying victimization identification and large language model-assisted assessment: a study of cyberbullying victimization lexicon construction and validation.

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
Introduction: Cyberbullying poses a global mental health threat, yet its accurate identification remains challenging due to biases in self-reporting and help-seeking barriers. Methods: Based on large-scale social media data, the present study constructed a Chinese cyberbullying victimization lexicon from three dimensions-cyberbullying methods (the types of cyberbullying experienced by the individual), perceived harm (the harm perceived by the victim), and coping strategies (the behavioral responses adopted by the victim)-using Weibo texts, psychological lexicons, and cyberbullying questionnaires. This approach aims to improve the precision of victim identification and facilitate timely intervention. Lexicon validity was evaluated by examining correlations between word-frequency statistics derived from 500 Weibo posts and expert ratings (n = 3). In addition, based on 3,442 RedNote posts, we preliminarily explored the lexicon's cross-platform applicability. To assess whether DeepSeek-R1 and GPT-4o could function as research assistants in dictionary construction, the present study replicated the manual lexicon development process-including text classification, vocabulary screening, weight assignment, and victimization severity assessment-and compared model outputs with human evaluations under simple and complex prompts using Cohen's Kappa, intraclass correlation coefficients (ICC), recall, and precision. Results: (1) The lexicon comprised 442 words across three dimensions: cyberbullying methods, perceived harm, and coping strategies. The lexicon demonstrated strong validity in identifying cyberbullying victimization expressions in social media text across each of the three sub-dimensions and the overall dimension (cyberbullying methods: r=0.500, p < 0.001; perceived harm: Discussion: As the first Chinese cyberbullying victimization dictionary, this research demonstrates that large language models offer preliminary utility in structured tasks but require human oversight for complex, large-scale research phases, supporting a human-machine collaborative approach for optimal outcomes.
