青少年心理韧性与非自杀性自伤行为的关系:有调节的中介模型

The Relationship between Resilience and Non-Suicidal Self-Injury Behaviors in Adolescents:A Moderated Mediation Model

目的:探讨青少年心理韧性与非自杀性自伤(non-suicidal self-injury,NSSI)行为的关系,以及孤独感的中介作用和睡眠问题的调节作用。方法:采用分层整群抽样的方法,选取长沙市1100名在校中学生,通过问卷调查测量中学生的抑郁程度、焦虑程度、NSSI行为、心理韧性、孤独感水平、睡眠问题及反刍思维等,共回收有效问卷1011份。结果:多变量logistic回归表明,居住类型、抑郁程度、焦虑程度、孤独感和睡眠问题与NSSI行为的发生显著相关。孤独感在心理韧性与NSSI之间的中介作用显著,且孤独感对NSSI行为的影响受到睡眠问题的调节。结论:提高青少年的心理韧性、减轻孤独感并保证青少年拥有较高的睡眠质量将有助于青少年NSSI行为的预防。

Objective:To explore the relationship between psychological resilience and non-suicidal self-injury(NSSI)behaviors in adolescents,as well as the mediating role of loneliness and the moderating effect of sleep problems.Methods:Using a stratified cluster sampling method,1100 middle school students in Changsha were selected.A questionnaire survey was conducted to measure demographic information,depression,anxiety,NSSI behaviors,psychological resilience,loneliness,sleep problems,and rumination.A total of 1011 valid questionnaires were collected.Results:Multivariate logistic regression showed that living arrangements,depression,anxiety,loneliness,and sleep problems were significantly associated with NSSI behaviors.In the mediation-moderation model,loneliness significantly mediated the relationship between psychological resilience and NSSI,and the effect of loneliness on NSSI behaviors was moderated by sleep problems.Conclusion:Strengthening the resilience of adolescents,reducing their loneliness,and ensuring their sleep quality will contribute to the prevention of NSSI behaviors in adolescents.
