Existing literature is supportive for the positive connection between impulsivity and self-harm (SH), nevertheless, less is known regarding to the role of resilience in this association. This research primarily explored potential mediation of resilience in the association between impulsivity and SH in a large sample of Chinese adolescents.
A population-based cross-sectional survey of 4552 adolescents was conducted in southwest China. A self-administered questionnaire was adopted for data collection from all subjects. The Barratt Impulsiveness Scale (BIS), the Modified version of Adolescents Self-Harm Scale (MASHS) and the Resilience Scale for Chinese Adolescents (RSCA) were used to measure impulsivity, SH, and resilience, respectively. The associations between impulsivity, resilience, and SH were estimated by using stepwise multivariate Logistic regression models. Mediation of resilience in impulsivity and SH association was evaluated by using path model.
The prevalence of SH was 39.1% (95% CI: 34.0%-45.0%) for surveyed adolescents. Impulsivity and resilience were significantly associated with the prevalence of SH. Prominent dose-response association between impulsivity and SH prevalence was further confirmed. Resilience was a salient mediator which accounted for 42.90% of the total impulsivity-SH association. Among all the five dimensions of resilience, goal concentration (23.98%) and emotion regulation (21.94%) showed the strongest mediation.
The findings suggest that resilience building intervention strategies, particularly those focusing on improving goal concentration, emotion regulation, and positive perception, could be effective in reducing impulsivity related SH risk among Chinses adolescents.
现有文献支持冲动性与自伤（SH）之间存在正相关，但对于韧性在这种关联中的作用知之甚少。本研究主要探讨了在大规模中国青少年样本中，韧性在冲动性与 SH 之间的关联中的潜在中介作用。
在中国西南部进行了一项基于人群的横断面调查，共纳入 4552 名青少年。采用自填式问卷收集所有受试者的数据。使用巴瑞特冲动量表（BIS）、改良青少年自伤量表（MASHS）和中国青少年韧性量表（RSCA）分别测量冲动性、SH 和韧性。使用逐步多元 Logistic 回归模型估计冲动性、韧性和 SH 之间的关联。使用路径模型评估韧性在冲动性和 SH 关联中的中介作用。
调查青少年的 SH 患病率为 39.1%（95%CI：34.0%-45.0%）。冲动性和韧性与 SH 的患病率显著相关。进一步证实了冲动性与 SH 患病率之间存在明显的剂量反应关系。韧性是一个显著的中介变量，占冲动性-SH 关联的 42.90%。在韧性的所有五个维度中，目标专注（23.98%）和情绪调节（21.94%）表现出最强的中介作用。
研究结果表明，韧性建设干预策略，特别是那些注重提高目标专注、情绪调节和积极认知的策略，可能对降低中国青少年与冲动性相关的 SH 风险有效。
