Background

There is a complex and inconsistent relationship between bullying involvement and self-harmful thoughts and behaviour (SHTB) in young people. This novel systematic review aims to establish key interacting, moderating and mediating variables associated with SHTB in young people involved in bullying.

Methods

The systematic review was registered with PROSPERO: CRD42020192023. A search was conducted (until February 2021) across databases: PubMed/MEDLINE, EMBASE, PsycINFO (Ovid), Cochrane Library, Scopus (Elsevier), Web of Science, ERIC and CINAHL (EBSCOhost). Observational studies containing quantitative primary or secondary data analyses were included in the review, on the basis that they examined interactions, moderators, or mediators between bullying involvement and SHTB in young people. Versions of the Newcastle-Ottawa Scale were used to assess risk of bias in the included studies.

Results

A total of 57 studies were included. Overall, 3 studies identified interactions, 25 studies identified moderators and 21 studies identified mediators. 9 studies identified moderator-mediators. The findings were categorised as either self-harmful thoughts or self-harmful behaviours and synthesised under the following themes: socio-demographic; depression; parental; personality/psychological; and social/environmental.

Limitations

This review uncovered significant heterogeneity and a paucity of replicated studies in the field, therefore, tentative conclusions have been drawn.

Conclusions

This comprehensive review highlights the key role of depression as a mediator between traditional/cyber victimisation and SHTB in young people. The moderating effects of gender on mediation models investigating the role of depression suggest the possibility that females involved in bullying may be at increased suicide risk.

调查青少年欺凌参与与自残思想和行为之间的关系：系统评价

背景

青少年的欺凌参与与自残思想和行为 (SHTB) 之间存在复杂且不一致的关系。这篇新颖的系统评价旨在确定参与欺凌的年轻人与 SHTB 相关的关键交互、调节和中介变量。

方法

系统评价已在 PROSPERO 注册：CRD42020192023。对数据库进行了搜索（直到 2021 年 2 月）：PubMed/MEDLINE、EMBASE、PsycINFO (Ovid)、Cochrane Library、Scopus (Elsevier)、Web of Science、ERIC 和 CINAHL (EBSCOhost)。该评价纳入了包含定量一手或二手数据分析的观察性研究，其基础是它们检查了青少年欺凌参与与 SHTB 之间的相互作用、调节因素或中介因素。纽卡斯尔-渥太华量表版本用于评估纳入研究的偏倚风险。

结果

共纳入 57 项研究。总体而言，3 项研究确定了相互作用，25 项研究确定了调节因素，21 项研究确定了中介因素。9 项研究确定了调解人-调解人。调查结果被归类为自残思想或自残行为，并在以下主题下综合：社会人口学；沮丧; 父母；性格/心理；和社会/环境。

限制

本综述揭示了该领域的显着异质性和缺乏重复研究，因此得出了初步结论。

结论

这篇全面的综述强调了抑郁症在年轻人中作为传统/网络受害和 SHTB 之间的中介的关键作用。性别对调查抑郁作用的中介模型的调节作用表明，参与欺凌的女性可能会增加自杀风险。
