Abstract

BACKGROUND

Left-behind adolescents are vulnerable to stressful life events and often engage in nonsuicidal self-injury (NSSI), which is a growing public concern in China. However, little is known about the synergistic protective effect of family resources on the relationship between stressful life events and NSSI in these adolescents.

OBJECTIVE

Based on theories of family socialization and resilience, the aim of this study was to examine the synergistic protective role of maternal knowledge and mother-child cohesion in buffering the effect of stressful life events on NSSI in father-absent left-behind adolescents.

METHODS

This study used two-wave longitudinal data. The analytical sample included 673 adolescents (M = 13.47 ± 1.11 years, 48 % male) who were enlisted from 4 junior high schools in rural China. Respondents completed questionnaires on stressful life events, parental knowledge, parent-child cohesion, and NSSI at two-time points.

RESULTS

The effects of stressful life events on NSSI were significant in father-absent left-behind adolescents. Additionally, maternal knowledge moderated the associations between stressful life events and NSSI in father-absent left-behind adolescents. Moreover, maternal knowledge and mother-child cohesion were found to play synergistic protective roles in the relationship between stressful life events and NSSI. In father-absent left-behind adolescents, only high maternal knowledge and high-quality mother-child cohesion could eliminate the negative effect of stressful life events on NSSI.

CONCLUSION

The findings underscore the synergistic protective roles of maternal knowledge and mother-child cohesion in buffering the negative effect of stressful life events on NSSI in father-absent left-behind adolescents. Both maternal knowledge and mother-child cohesion should be considered in interventions aimed at reducing NSSI in these adolescents.

摘要

背景

留守青少年容易受到生活压力事件的影响，经常进行非自杀性自伤（NSSI），这在中国是一个日益受到关注的公共卫生问题。然而，人们对家庭资源对这些青少年生活压力事件与 NSSI 之间关系的协同保护作用知之甚少。

目的

基于家庭社会化和弹性理论，本研究旨在检验母亲知识和母子凝聚力在缓冲父亲缺失留守青少年生活压力事件对 NSSI 影响方面的协同保护作用。

方法

本研究使用两波纵向数据。分析样本包括来自中国农村 4 所初中的 673 名青少年（M=13.47±1.11 岁，48%为男性）。被试在两个时间点上完成了关于生活压力事件、父母知识、亲子凝聚力和 NSSI 的问卷。

结果

生活压力事件对父亲缺失留守青少年的 NSSI 有显著影响。此外，母亲知识调节了父亲缺失留守青少年生活压力事件与 NSSI 之间的关系。而且，母亲知识和母子凝聚力在生活压力事件与 NSSI 之间发挥了协同保护作用。在父亲缺失的留守青少年中，只有高母亲知识和高质量的母子凝聚力才能消除生活压力事件对 NSSI 的负面影响。
