Substantial evidence indicates that adolescents and young adults have a disproportionately high incidence of most forms of violence, including suicide. Suicidality often includes suicidal ideation. The present study examined the relationship between bullying and suicidal ideation, and further tested whether social support moderates the association between the dimensions of bullying (verbal bullying, physical bullying, and bullying victimization) and suicidal ideation among adolescent secondary school students. A cross-sectional design was adopted for the study. Participants were 394 students (249 boys, 145 girls) drawn from two secondary schools in Nsukka semi-urban area, in southeast Nigeria. Participants completed the Illinois Bully Scale, the Columbia-Suicide Severity Rating Scale, and the Multidimensional Scale of Perceived Social Support (MSPSS). Hayes’ regression-based PROCESS macro was used to analyze the data. Verbal bullying, physical bullying, and victimization were independently positively associated with suicidal ideation. Social support was not independently significantly associated with suicidal ideation, but it moderated the relationship between victimization and suicidal ideation. The positive relationship between victimization and suicidal ideation was strongest for adolescents who had low social support, compared to those who had moderate or high social support. This finding is consistent with the buffering hypothesis of social support, suggesting that supportive relationships for victims can mitigate suicidal ideation.

欺凌和自杀意念：在撒哈拉以南非洲样本中检验社会支持的缓冲假设


大量证据表明，大多数形式的暴力（包括自杀）在青少年和年轻人中的发生率异常高。自杀往往包括自杀意念。本研究探讨了欺凌与自杀意念之间的关系，并进一步测试了社会支持是否调节青少年中学生欺凌维度（言语欺凌、身体欺凌和欺凌受害）与自杀意念之间的关联。本研究采用横断面设计。参与者是来自尼日利亚东南部 Nsukka 半城区两所中学的 394 名学生（249 名男生，145 名女生）。参与者完成了伊利诺伊州欺凌量表、哥伦比亚自杀严重程度评定量表和感知社会支持多维量表（MSPSS）。 Hayes 基于回归的 PROCESS 宏用于分析数据。言语欺凌、身体欺凌和受害与自杀意念独立呈正相关。社会支持与自杀意念并不独立显着相关，但它调节了受害与自杀意念之间的关系。与社会支持中等或较高的青少年相比，社会支持较低的青少年受害与自杀意念之间的正相关关系最强。这一发现与社会支持的缓冲假说一致，表明对受害者的支持性关系可以减轻自杀意念。
