Few empirical studies have explored the role of perceived school bullying (PSB) on suicidal ideation (SI) in adolescents, through the mediating mechanisms of psychotic-like experiences (PLEs) and depressive symptoms (DS). This study utilized a large sample of adolescents with three waves of data collection at 6-month intervals to examine the longitudinal effect of PSB on SI after 6 months and 1 year, as well as the mediation of PLEs and DS in the PSB-SI relationship. A total of 4,595 adolescents in the 7th grade (mean age = 13.03, 52% male) participated in the three-wave longitudinal study on adolescent mental health conducted between May 2021 and May 2022 in a city in South China. The measures included T1 PSB assessed using the Delaware School Climate Scale-Student (DSCS-S), T2 PLEs measured using the Positive Subscale of the Community Assessment of Psychic Experiences (CAPE-P8), T2 DS assessed using the Patient Health Questionnaire-2 (PHQ-2), and T3 SI measured using the Patient Health Questionnaire (PHQ-9). The prevalence rate of adolescents PLEs (T1 = 43.7%, T2 = 55.5%), DS (T1 = 11.1%, T2 = 12.0%), and SI (T1 = 17.8%, T2 = 16.8%, T3 = 17.7%) were reported. The prevalence rates of SI from T1 to T3 significantly increased with increases in the baseline levels of PSB, PLEs, and DS. Mediation analyses revealed that PLEs and DS at 6 months significantly mediated the association between PSB at baseline and SI 1 year later.
很少有实证研究通过类精神病体验（PLEs）和抑郁症状（DS）的中介机制，探讨青少年中感知到的校园欺凌（PSB）对自杀意念（SI）的作用。本研究采用了一大群青少年样本，每隔6个月进行三次数据收集，以检验PSB在6个月和1年后对SI的纵向影响，以及PLEs和DS在PSB与SI关系中的中介作用。2021年5月至2022年5月期间，在中国南方一个城市对4595名七年级青少年（平均年龄 = 13.03岁，52%为男性）进行了关于青少年心理健康的三波纵向研究。测量指标包括：使用特拉华学校氛围量表 - 学生版（DSCS - S）评估的T1期PSB；使用精神体验社区评估的积极子量表（CAPE - P8）测量的T2期PLEs；使用患者健康问卷 - 2（PHQ - 2）评估的T2期DS；以及使用患者健康问卷（PHQ - 9）测量的T3期SI。报告了青少年PLEs（T1 = 43.7%，T2 = 55.5%）、DS（T1 = 11.1%，T2 = 12.0%）和SI（T1 = 17.8%，T2 = 16.8%，T3 = 17.7%）的患病率。从T1到T3，SI的患病率随着PSB、PLEs和DS基线水平的升高而显著增加。中介分析表明，6个月时的PLEs和DS显著中介了基线时PSB与1年后SI之间的关联。
