中文摘要：

研究采用儿童自恋人格问卷、网络欺负行为量表和社会地位不安全感问卷,通过对890名中美青少年的问卷调查,探讨了青少年自恋与网络欺负行为的关系以及社会地位不确定感的中介效应。结果发现：（1）中美两国青少年在社会地位不安全感上存在显著差异;（2）自恋、社会地位不安全感和网络欺负行为两两之间均显著正相关;（3）青少年自恋可以正向预测网络欺负行为,同时社会地位不安全感在自恋和网络欺负行为之间起中介作用;（4）中美两国样本社会地位不安全中介模型均可接受,但在部分路径上存在显著差异。

英文摘要：

The current study investigated the mediating effect of social status insecurity between narcissism and cyberbullying and explored whether these relationships varied between Chinese and US adolescents. Childhood narcissism scale, self-reported cyber aggression scale and social status insecurity scale were ad- ministered to 407 Chinese and 483 US adolescents. Results showed that： （1） US adolescents had higher levels of social status insecurity than Chinese adolescents; （2） Narcissism and social status insecurity were all positively correlated with cyberbullying in the adolescents; （3） Narcissism had a positive prediction on cyberbullying, and social status insecurity mediated the relationship between narcissism and cyberbullying; （4） The mediation model was accepted among both Chinese and US sample. However both pathway be- tween narcissism and cyberbullying and pathway between social statue insecurity and cyberbullying varied across the nation.
