相对剥夺感影响网络集群攻击行为：一个有调节的双路径模型

以598名大学生为被试,采用问卷法考察群体相对剥夺与网络集群攻击行为的关系,检验以群体愤怒和群体效能为中介变量的双路径模型及群体认同在双路径模型中所发挥的调节作用。结果发现：（1）群体相对剥夺显著正向预测网络集群攻击行为;（2）群体愤怒和群体效能在群体相对剥夺与网络集群攻击行为之间有中介作用;（3）群体认同在群体相对剥夺通过群体愤怒和群体效能影响网络集群攻击行为的双路径模型中起调节作用。

Effects of Relative Deprivation on Cyber Collective and Aggressive Behaviors: A Moderated Dual-pathway Models

With the cyber group events and cyber violence incidents occurring frequently, researchers have been gradually paying more and more attention on cyber collective and aggressive behaviors. At present, there are only a few theoretical and related researches which are mainly based on the collective behavior theories such as value added theory to analyze and explain the cyber collective and aggressive behaviors. The formation of cyber collective and aggressive behaviors is a complex process, influenced by many variables which are not independent but interacted and mutual influenced the production. Therefore, the current study aimed to examine the relationships between group relative deprivation and cyber collective and aggressive behaviors. In addition, the current study investigated whether the associations were mediated by group-based anger and group efficacy and whether group identity moderated the relationship between group relative deprivation and cyber collective and aggressive behaviors mediated by group-based anger and group efficacy. In order to reach the aim, the questionnaire survey was carried out by using the adaptation of "Mercedes Man striking event" as the background. And 598 undergraduates from different grades and majors took part in the research in the unit of the class. Both surveys included demographics in the first part, followed by a questionnaire on group relative deprivation, cyber collective and aggressive behaviors, group-based anger, and group efficacy and group identity. Most of the questions were based on former researches and were modified for the specific situation. Data was collected and analyzed using SPSS 21.0. The results were as follows: (1) there were significant correlations between group relative deprivation, group-based anger, group efficacy, and group identity and cyber collective and aggressive behaviors. (2) Mediation analyses indicated that both group-based anger and group efficacy mediated the relationships between group relative deprivation and cyber collective and aggressive behaviors. (3) Moderation analyses showed that group identity moderated the mediation effect of group-based anger and group efficacy. In terms of group anger as an intermediary, the indirect effect was stronger for individuals with high group identity than for those with low group identity. Similarly, for individuals with high group identity, the mediating effect of group efficacy was not significant, and group relative deprivation only had a direct effect on cyber collective and aggressive behaviors. (4) There were two moderated mediation models including group relative deprivation, cyber collective and aggressive behaviors, group-based anger, and group efficacy and group identity. Confirmatory factor analysis indicated that all fit indexes conformed to statistical requirements. In summary, the current study goes beyond previously applied designs by examining the mediating mechanism caused by group-based anger and group efficacy, and represents an important step in the investigation of how group relative deprivation relates to cyber collective and aggressive behaviors by moderation of group identity. Furthermore, these mediating mechanisms were moderated by group identity. Findings from this study highlighted the importance of studying cyber collective and aggressive behaviors simultaneously and broaden our understanding of the factors and processes that provided a new research idea on how to explore and reduce cyber collective and aggressive behaviors.
