Evaluating potential effect of adverse childhood experiences on depressive symptoms in Chinese middle-aged and older adults: a simulation-based 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. Cited by 1 paper.
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
backgroundMost studies examining the association between adverse childhood experiences (ACEs) and depressive symptoms using traditional regression analyses fail to capture how specific types of ACEs relate to certain depressive symptoms, thereby impeding deeper insight into their associations. A simulation-based network analysis provides a novel approach to explore these complex interrelationships.
objectivesThis study aims to explore the complex relationship between ACEs and depressive symptoms, and to identify the types of ACEs that most strongly influence depressive symptoms among middle-aged and older.
methodsWe conducted a secondary analysis of data from the China Health and Retirement Longitudinal Study. Depressive symptoms were assessed using 10-item Center for Epidemiologic Studies Depression Scale. 8 ACEs indicators were obtained through self-reported questionnaires. The Ising model was used to estimate the network structure and analyze the bridge indices of each node. The NodeIdentifyR algorithm was applied to simulate the effects of hypothetically decreasing or increasing the activation of individual ACE nodes on the summed scores of the depressive symptom network. An age-stratified analysis (45–60 vs. ≥60 years) was further conducted to test the robustness of the results.
resultsThe final analysis included 13,771 participants aged ≥ 45 years. The Ising model indicated that household mental illness (HMI) showed the highest bridge centrality. Under hypothetical scenarios of increased node activation, HMI was associated with the largest increase in overall depressive symptom network activation, suggesting a critical risk factor for symptom worsening. In contrast, under hypothetical scenarios of reduced node activation, parental death (PD) showed the greatest reduction in projected depressive symptom sum scores, indicating that PD could have a propelling effect on depressive symptom levels. An age-stratified analysis reached consistent results. DISCUSSION: Our findings indicate that HMI and PD represent critical markers for early detection of depression risk in middle-aged and older adults.
