新冠疫情期间学生心理应激反应与非自杀性自伤行为:有调节的中介模型

为了探究在新冠疫情期间学生群体的心理应激反应和非自杀性自伤行为的关系，以及消极应对方式的中介作用和情绪管理能力的调节作用，以线上问卷的形式，采用心理应激反应筛查问卷、简易应对方式问卷、情绪管理能力量表、非自杀性自伤行为功能评估工具，在疫情期间对国内1 955名学生进行调查. 结果显示:疫情期间学生的心理应激反应和自伤行为呈显著正相关；消极应对方式在心理应激反应和非自杀性自伤行为之间起部分中介作用；消极应对方式和非自杀性自伤行为的关系(中介效应的后半段路径)受到情绪管理能力的调节:情绪管理能力越强，消极应对方式对非自杀性自伤行为的正向预测作用越弱. 研究表明:心理应激反应和非自杀性自伤行为之间存在着有调节的中介效应，消极应对方式是其中的中介变量，情绪管理能力是其中的调节变量，后者能够降低前者对非自杀性自伤的影响.

The Impact of Psychological Stress Response on Non-suicidal Self-injury Behaviors in Adolescents during COVID-19

To study the relationship between psychology stress response and non-suicidal self-injury behaviors, the mediating effect of negative coping style and the moderating effect of emotional management ability among students during the COVID-19 epidemic, the Psychological Stress Reaction Questionnaire, the Non-suicide Behavioral Assessment Tool, the Simplified Coping Style Questionnaire and the Emotion Management Questionnaire were employed to investigate the mental health of 1 955 students. The results showed that psychology stress response was significantly positively correlated to non-suicidal self-injury behaviors; negative coping style played a partial mediating role between psychology stress response and non-suicidal self-injury behaviors and the mediating effect was affected by emotional management ability. The relationship between negative coping style and non-suicidal self-injury behaviors (the second half of the mediation effect) was moderated by emotional management ability; the higher the emotional management ability of the subjects, the weaker effects of negative coping style on the positive prediction of non-suicidal self-injury behaviors. The research suggested that the relationship between psychology stress response and non-suicide self-injury behaviors was mediated, negative coping style played a partial mediating role between them, and emotional management ability can buffer the impact of negative coping style on non-suicide self-injury behaviors.
