現今的人際關係交流不在侷限於面對面，而是發展到了網際網路上社群媒體的交流。正因為在社群媒體上的互動日益增加，進而改變了霸凌的型態，隨著傳統霸凌延伸到了網路霸凌。再加上，網路社群媒體匿名的特性而使得霸凌者更加肆無忌憚攻擊他人使得網路霸凌的情況跟著加劇。有鑑於網路霸凌事件日益嚴重，造成了許多社會悲劇事件，因此本研究主要在探討影響網路霸凌行為之因素，是什麼因素讓網路使用者在鍵盤留下負面的評論。因此，本研究以去個體化、遏止理論、從眾效應和低自我控制理論為基礎，建構一個完整的研究模型來解釋網路霸凌的行為因素，並且實際驗證。此外，與其他相關研究不同的是，本研究將低自我控制當作調節變量，以衡量不同人格特質的網路使用者對網路霸凌的程度是否有不同。
本研究於網路社群回收了269份有效樣本以驗證本研究模型，其結果支持我們所做的推論，去個體化、遏止理論和從眾效應都會影響網路使用者是否做出網路霸淩行為的因素，並且在低自我控制的調節下，較喜愛尋求刺激的人相對下會忽略遏止的力量而有較高機率做出網路霸凌行為。
本研究的結果，整合了過去幾個較常被拿來討論網路霸凌行為的觀點。

Today's interpersonal communication is not limited to face-to-face communication but has developed into social media on the Internet. It is precisely because of the increasing interaction on social media that the traditional form of bullying has now extended to online bullying. The anonymity of online social media has allowed bullies to be less scrupulous about attacking others, which has intensified the issue of online bullying. Given the many social tragedies caused by this issue, and in view of the increasing severity of cyberbullying incidents, this study explores the factors that affect cyberbullying behavior and cause Internet users to leave negative comments via the keyboard. Based on deindividuation, containment theory, the bandwagon effect, and low self-control theory, we construct and actually verify a complete research model to explain the behavioral factors of cyberbullying. Unlike other related studies, this study uses low self-control as a regulating variable to measure the extent to which Internet users with different personality traits engage in cyberbullying.
We collected 269 valid samples from the online community to validate the research model. The results support our inferences. Deindividuation, the factors in containment theory, and the bandwagon effect all affect whether Internet users perform cyberbullying behaviors. Under the regulation of the factors comprised in low self-control theory, those who prefer to seek stimulation are found to be immune to the power of deterrence and to have a higher probability of performing cyberbullying behaviors.
As a result, our study integrates several views that have been used to discuss cyberbullying behavior in the past.
