Caught in the web of polyvictimization: Network analysis of theoretical clusters versus data-driven groupings of potentially traumatic events among adolescents.
Article in Child abuse & neglect, 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
backgroundExposure to multiple potentially traumatic events (PTEs; e.g., maltreatment, family or community violence), is a robust risk factor for posttraumatic stress disorder (PTSD). Identifying patterns of PTE exposure (i.e., polyvictimization) is essential for understanding youth risk for subsequent PTE exposure and mental health outcomes.
objectiveThe current study used network analysis to characterize interrelations among PTEs and their connections to PTSD symptoms, and examined whether theoretically grounded classifications versus data-driven constellations of individual PTEs differentially capture polyvictimization patterns and associations with symptoms.
methodsData were drawn from 3614 youth (M
resultsResults from categorical and individual networks revealed both distinct and overlapping polyvictimization and symptom patterns. Aggregating PTEs into broad categories obscured key connections among "lower severity" PTEs (e.g., caregiver spanking/slapping, touching on private parts) that were strongly linked to polyvictimization and symptoms.
conclusionsTheoretical, broad groupings may not accurately reflect patterns of PTE exposure in youth. Findings highlight the value of data-driven approaches and the importance of assessing individual PTEs to capture the complexity of polyvictimization. Results also highlight potential targets for prevention and intervention among PTE exposed youth (e.g., caregiver behaviors) and provide guidance for future the operationalization of polyvictimization in studies linking PTE and emotional and behavioral health outcomes.
