  "abstract": "Background: Childhood abuse is associated with adolescent non-suicidal self-injury (NSSI), but the roles of proximal peer experiences and family context remain unclear.\n\nMethods: A cross-sectional survey was conducted among 10,179 Chinese students (47.9% female; Mage = 14.16 years, SD = 1.86). A theoretically motivated model re-specified during peer review examined peer victimization as a statistical mediator and family dynamics (SSFD) as a moderator of the a, b, and direct paths. Analyses controlled for gender, age, and parental education and used 5,000 bootstrap resamples.\n\nResults: Childhood abuse was positively associated with NSSI (total association: β = 0.476, p < .001). The statistical indirect association through peer victimization was 0.150 (95% CI [0.133, 0.167]). Small positive interactions were observed for CA × SSFD predicting peer victimization (β = 0.033, p < .001), PV × SSFD predicting NSSI (β = 0.031, p = .001), and CA × SSFD predicting NSSI (β = 0.046, p < .001). The interactions explained little additional variance (ΔR² = 0.001 for peer victimization and 0.005 jointly for NSSI). Conditional indirect associations were 0.109 at low SSFD and 0.157 at high SSFD; their bootstrap contrast was 0.048 (95% CI [0.011, 0.083]).\n\nConclusions: The findings are compatible with an associational indirect pattern involving peer victimization and small conditional differences by family dynamics. Because all variables were self-reported at one time point, and the model was re-specified during review, the results should not be interpreted as evidence of causal or developmental mechanisms.\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1186/s40359-026-05284-w.",
