中文摘要:
      背景 青少年非自杀性自伤(NSSI)行为已成为全球公共卫生的关注重点。焦虑与抑郁被视为NSSI行为的重要影响因素,社会支持可能在缓解情绪和行为问题方面发挥保护作用。现有研究多聚焦于单一因素对NSSI行为的直接影响,而对焦虑、抑郁和社会支持三者共同作用的可信性证据不足。目的 探讨焦虑对青少年NSSI行为的影响和抑郁在其中的中介作用以及社会支持的调节作用,以期为青少年NSSI行为的预防和干预提供参考。方法 于2022年2月,选取成都市某区所有10所中学七至十二年级学生40 820名,采用广泛性焦虑障碍量表(GAD-7)、患者健康问卷抑郁量表(PHQ-9)、青少年社会支持评定量表(SSSUS)以及青少年自我伤害问卷(ASHS)进行评定。使用Pearson相关分析检验存在NSSI行为的青少年各量表评分之间的相关性。采用SPSS宏程序Process 3.5进行有调节的中介模型分析,并通过Bootstrap法检验中介和调节效应。采用简单斜率分析考查交互效应。结果 共34 534名(84.60%)青少年完成有效问卷调查,检出542名(1.57%)青少年存在NSSI行为。有无NSSI行为的青少年性别、GAD-7评分、PHQ-9评分以及SSSUS评分比较,差异均有统计学意义(χ2/t=62.889、71.120、94.365、-41.464,P均<0.01)。存在NSSI行为的青少年GAD-7评分与ASHS评分和PHQ-9评分均呈正相关(r=0.158、0.166,P均<0.01);PHQ-9评分与ASHS评分呈正相关(r=0.364,P<0.01),与SSSUS评分呈负相关(r=-0.290,P<0.01);SSSUS评分与ASHS评分呈负相关(r=-0.247,P<0.01)。抑郁在焦虑与NSSI行为之间起部分中介作用,效应值为0.544(95% CI:0.162~0.944),效应量为35.79%。社会支持在抑郁与NSSI行为之间起调节作用,效应值为-0.082(95% CI:-0.135~-0.029)。结论 焦虑不仅直接影响青少年NSSI行为,还可通过抑郁的中介作用间接影响NSSI行为,社会支持对抑郁与NSSI行为之间的关系存在调节作用。
英文摘要:
      Background Non-suicidal self-injury (NSSI) behavior among adolescents has become a global public health concern. Anxiety and depression are considered key factors influencing NSSI behavior, while social support may play a protective role in alleviating emotional and behavioral issues. However, existing research has primarily focused on the direct impact of individual factors on NSSI behavior, with insufficient exploration of the combined effects of anxiety, depression and social support.Objective To investigate the direct effect of anxiety on NSSI, the mediating role of depression and the moderating role of social support in relationship between anxiety and NSSI behavior, thus to provide references for the prevention and intervention of NSSI behavior among adolescents.Methods In February 2022, a total of 40 820 students in grades 7 to 12 across 10 middle schools in a district of Chengdu were selected as participants, and they were assessed using Generalized Anxiety Disorder Scale-7 item (GAD-7), Patient's Health Questionnaire Depression Scale-9 item (PHQ-9), Social Support Scale for Urban Students (SSSUS) and Adolescent Self-Harm Scale (ASHS). Pearson correlation analysis was conducted to examine the correlations between scale scores among adolescents with NSSI behaviors. Mediation and moderation analyses were performed using Process 3.5 in SPSS, and the significance was tested with bootstrapping. The interaction was visualized by using simple slope analysis.Results Among 34 534 (84.60%) valid respondents, 542 adolescents (1.57%) reported engaging in NSSI behavior. Significant differences in gender, GAD-7 scores, PHQ-9 scores, and SSSUS scores were observed between NSSI behavior group and non-NSSI group (χ2/t=62.889, 71.120, 94.365, -41.464, P<0.01).Adolesents with NSSI showed positive correlations between GAD-7 scores and both ASHS and PHQ-9 scores (r=0.158, 0.166, P<0.01). PHQ-9 scores were positively correlated with ASHS scores (r=0.364, P<0.01), but negatively correlated with SSSUS scores (r=-0.290, P<0.01). SSSUS scores were negatively correlated with ASHS scores (r=-0.247, P<0.01). Depression partially mediated the relationship between anxiety and NSSI behavior, with an effect size of 0.544 (95% CI: 0.162~0.944), accounting for 35.79% of the total effect. Social support moderated the relationship between depression and NSSI bahavior, with an effect value of -0.082 (95% CI: -0.135~-0.029).Conclusion Anxiety not only directly influences NSSI bahavior among adolescents, also indirectly exacerbates it through depression, while social support mitigates the impact of depression on NSSI behavior.
