The dynamic interplay of cyberbullying victimization and self-injury: a longitudinal investigation of rumination and friendship quality in Chinese vocational students.
Article in BMC psychology, 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
objectiveThis longitudinal study examined the relationship between cyberbullying victimization (CV) and non-suicidal self-injury (NSSI) among Chinese vocational college students, testing the mediating role of ruminative contemplation (RC) and the moderating effect of friendship quality (FQ).
methodsA six-month longitudinal design was implemented with 2,312 vocational students (Mage(T1) = 19.06; 35.55% CV prevalence, 19.26% NSSI prevalence at baseline). Data were collected at two waves (T1: December 2024; T2: June 2025) using validated scales: Cyberbullying Inventory for College Students (CICS), Adolescent Self-Harm Questionnaire, Event-Related Rumination Inventory (C-ERRI), and Friendship Quality Questionnaire (FQQ-C). Cross-lagged panel models (CLPM) and moderated mediation analyses were conducted via Mplus 8.3, controlling for gender, only-child status, and residence.
resultsCV directly predicted increased NSSI over time. RC mediated the CV→NSSI link. FQ significantly buffered the direct CV→NSSI pathway, with maximal protection observed at FQ scores = 212.3 (Johnson-Neyman analysis).
conclusionsCyberbullying victimization heightens NSSI risk both directly and indirectly through ruminative contemplation. High-quality friendships mitigate this pathway, offering a critical protective factor for vocational students. Interventions should target RC reduction and FQ enhancement to disrupt the CV→NSSI trajectory.
