Cross-sectional associations have been documented between cybervictimization and suicidal risk; however, prospective associations remain unclear.
Participants were members of the Quebec Longitudinal Study of Child Development (QLSCD), a prospective birth cohort of 2,120 individuals followed from birth (1997/98) to age 17 years (2014/15). Cybervictimization and face-to-face victimization experienced since the beginning of the school year, as well as serious suicidal ideation and/or suicide attempt were self-reported at ages 13, 15 and 17 years.
In cross-sectional analyses at 13, 15 and 17 years, adolescents cybervictimized at least once had, respectively, 2.3 (95% CI = 1.64-3.19), 4.2 (95% CI = 3.27-5.41) and 3.5 (95% CI = 2.57-4.66) higher odds of suicidal ideation/attempt after adjusting for confounders including face-to-face victimization, prior mental health symptoms and family hardship. Sensitivity analyses suggested that cybervictimization only and both cyber- and face-to-face victimization were associated with a higher risk of suicidal ideation/attempt compared to face-to-face victimization only and no victimization; however, analyses were based on small n. In prospective analyses, cybervictimization was not associated with suicidal ideation/attempt 2 years later after accounting for baseline suicidal ideation/attempt and other confounders. In contrast, face-to-face victimization was associated with suicidal ideation/attempt 2 years later in the fully adjusted model, including cybervictimization.
The cross-sectional association between cybervictimization and suicidal ideation/attempt is independent from face-to-face victimization. The absence of a prospective association suggested short-term effects of cybervictimization on suicidal ideation/attempt.
已有研究记录了网络欺凌与自杀风险之间的横断面关联,但前瞻性关联尚不清楚。
参与者为魁北克儿童发展纵向研究(QLSCD)的成员,这是一项前瞻性出生队列研究,共纳入 2120 名个体,从出生(1997/98 年)开始随访至 17 岁(2014/15 年)。13、15 和 17 岁时,青少年自我报告了自学年开始以来经历的网络欺凌和面对面欺凌,以及严重的自杀意念和/或自杀企图。
在 13、15 和 17 岁的横断面分析中,至少遭受过一次网络欺凌的青少年在调整了包括面对面欺凌、既往心理健康症状和家庭困难在内的混杂因素后,自杀意念/企图的可能性分别增加了 2.3 倍(95%CI=1.64-3.19)、4.2 倍(95%CI=3.27-5.41)和 3.5 倍(95%CI=2.57-4.66)。敏感性分析表明,与仅遭受面对面欺凌和无欺凌相比,仅遭受网络欺凌和同时遭受网络和面对面欺凌与自杀意念/企图的风险增加相关;然而,这些分析的样本量较小。在前瞻性分析中,在考虑了基线自杀意念/企图和其他混杂因素后,网络欺凌与 2 年后的自杀意念/企图无关。相比之下,在完全调整的模型中,包括网络欺凌在内,面对面欺凌与 2 年后的自杀意念/企图相关。
网络欺凌与自杀意念/企图之间的横断面关联独立于面对面欺凌。网络欺凌与自杀意念/企图之间无前瞻性关联表明网络欺凌对自杀意念/企图有短期影响。
