Childhood trauma and recent suicide risk in major depressive disorder: exploring the mediating effect of resilience and cognitive emotion regulation strategies.
Article in BMC psychiatry, 2025. 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
backgroundThe mechanisms through which childhood trauma contributes to increased suicide risk in individuals diagnosed with major depressive disorder (MDD) have not been comprehensively explored. This study aimed to investigate the role of resilience and cognitive emotion regulation strategies in the link between childhood trauma and recent suicide risk in MDD patients.
methodsThe study included 136 MDD patients and 112 healthy participants. Standardized instruments were utilized to collect demographic and clinical data, including the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Generalized Anxiety Disorder Scale (GAD-7), the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Cognitive Emotion Regulation Questionnaire (CERQ), and the Connor-Davidson Resilience Scale (CD-RISC). Structural equation modeling (SEM) was employed, and mediation analysis was conducted.
resultsSignificant correlations were observed between recent suicide risk in MDD patients and various factors, including childhood trauma (emotional abuse, emotional neglect; positive correlation), maladaptive strategies (positive correlation), and resilience traits (tenacity, strength, optimism; negative correlations). An ordinal logistic regression identified gender and maladaptive strategies as significant predictors of suicide risk. Most importantly, the bootstrap test showed that the direct effect (β = 0.114, 95% CI: -0.103–0.362) of childhood trauma on recent suicide risk was not significant, but the indirect (β = 0.224, 95% CI: 0.099–0.461) and total effects (β = 0.338, 95% CI: 0.180–0.552) of childhood trauma on recent suicide risk were significant.
conclusionsBuilding on cross-sectional data, our path analysis supports a model in which childhood trauma exerts its influence on recent suicide risk in MDD patients indirectly through resilience and emotion regulation, rather than through direct effects. In terms of suicide risk prevention and intervention for MDD patients with childhood trauma, the application of emotion regulation-oriented intervention measures is recommended.
