Stressful life events and non-suicidal self-injury among college students: chain mediating effect analysis of resilience and emotion dysregulation.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundNon-suicidal self-injury (NSSI) behavior represents a worrisome mental health concern across the world, with stressful life events emerging as a critical proximal predictor of NSSI behavior among college students. The high prevalence and severe implications of NSSI behavior necessitate a thorough investigation of the underlying mechanisms linking stressful life events to such maladaptive behavior among this vulnerable population.
objectiveThis study aims to delineate the psychological pathways through which stressful life events contribute to NSSI behaviors among college students, with a focus on the sequential mediating roles of resilience and emotion dysregulation.
methodsA cross-sectional convenience sample of 1,392 college students from Hunan Province, China, was recruited between September and December 2023. Data were collected via a structured online questionnaire, including the Ottawa Self-Injury Inventory (OSI), the Adolescent Self-Rating Life Events Checklist (ASLEC), the Difficulties in Emotion Regulation Scale (DERS), and the Resilience Scale for Chinese Adolescents (RSCA). Descriptive statistics, Pearson correlation analyses, hierarchical multiple regression analyses, and sequential mediation analysis were performed to evaluate the hypothesized relationships.
resultsThe prevalence of NSSI behavior was 7.54% (105/1392), lower than reported in Western populations but consistent with some regional Chinese estimates. Between-group comparisons revealed that the NSSI group demonstrated elevated total scores and scores across all dimensions on the ASLEC (p < 0.01) and DERS (p < 0.01), while exhibiting lower total scores and scores across all dimensions on the RSCA (p < 0.01). Correlation analysis indicated that NSSI behaviors were positively correlated with stressful life events (r = 0.408, p < 0.01) and emotion dysregulation (r = 0.430, p < 0.01), while negatively correlated with resilience (r = -0.592, p < 0.01). Sequential mediation analysis revealed that resilience and emotion dysregulation jointly mediated the effect of stressful life events on NSSI behaviors, highlighting a nuanced interplay of protective and vulnerability factors.
conclusionThese findings elucidate the intricate chain mediating effects of resilience and emotion dysregulation in the relationship between stressful life events and NSSI behaviors among college students. Given the cross-sectional design, causal inferences are constrained. Nonetheless, this study further provides valuable insights for the development and refinement of effective prevention strategies and intervention programs aimed at reducing NSSI risk.
