Symptom network for psychological distress in college freshmen: a large sample bayesian network analysis.
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
backgroundCollege students show a high prevalence of psychological distress, particularly during the freshman year. Investigating the network structure of psychological distress symptoms can reveal both comorbid patterns and potential directional relationships among symptoms.
methodsUsing data from a large sample of Chinese university students (N = 14,372), this study estimated a Gaussian graphical model (GGM) and a Bayesian network to explore undirected and directed connections among the nine core dimensions of the Symptom Checklist-90 (SCL-90).
resultsAnxiety exhibited the highest expected influence (EI) in the GGM, followed by interpersonal sensitivity and depression. In the DAG, depression and anxiety were located upstream in the network, with depression identified as the primary parent node, suggesting that emotional distress may serve as the “trigger” for the entire symptom network. Furthermore, interpersonal sensitivity demonstrated the highest betweenness and occupied a midstream position in the DAG, potentially functioning as a key hub linking other symptoms. Phobic anxiety emerged as a stable downstream node.
conclusionThese findings emphasize the importance of depression, anxiety, and interpersonal sensitivity in the network of psychological distress symptoms and highlight the value of early cognitive-emotional interventions and transdiagnostic strategies targeting symptom interactions. LIMITATIONS: This study did not collect detailed demographic information from participants or include other mental health scales for comparison, which limits the generalizability of the results.
