Gender-differentiated pathways from childhood trauma to self-injury: rumination as a mediator in depressed adolescents.

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
backgroundAmid the global escalation of adolescent depression and non-suicidal self-injury (NSSI), childhood trauma has been identified as a critical risk factor, yet how specific trauma subtypes contribute to NSSI remains unclear. This study aims to explore the relationship between childhood trauma subtypes and NSSI in depressed adolescents, focusing gender differences, and verify the mediating role of rumination.
methodsThis cross-sectional study included 2,006 clinically depressed adolescents (aged 10-19), who were recruited through convenience sampling from a psychiatric hospital in China (2024-2025). Validated scales (Childhood Trauma Questionnaire [CTQ], Ruminative Response Scale [RRS], Ottawa Self-Injury Inventory [OSI]) were administered. Binary logistic regression, subgroup analysis, and mediation analysis were used to examine the relationships between variables.
resultsNSSI prevalence reached 69.3% in depressed adolescents (female: 77.6% vs. male: 52.1%). Emotional neglect (EN, odds ratio [OR] = 1.82), emotional abuse (EA, OR = 2.06), and physical abuse (PA, OR = 2.55) were associated with NSSI. Gender difference analysis revealed that females were more sensitive to EN (OR = 2.30) and EA (OR = 2.06), while males were more sensitive to EA (OR = 2.07) and PA (OR = 2.12). A single trauma subtype significantly increased the risk of NSSI in females, whereas males required at least two trauma subtypes to significantly increase NSSI risk. Rumination played a mediating role between all trauma subtypes and NSSI, with sexual abuse (SA) showing the highest mediation effect (78.02%), indicating a full mediation effect.
conclusionsThe childhood trauma-NSSI association in depressed adolescents demonstrates gender difference, with rumination functioning as the central mechanistic pathway. Interventions must prioritize trauma subtype- and gender-tailored strategies to disrupt rumination pathways. CLINICAL TRIAL NUMBER: Not applicable.
