「電腦中介溝通」已被發現在使用者之間會產生較不受控制的行為，人們在網路上會感到較不受限制，會使用粗魯的言語、威脅性的字眼或是激進的批評來發洩他們的憤怒或憤恨。我們稱這種現象為「網路去抑制化行為」。
本實證研究提出了一個整合性的研究，結合了網路心理層面、社會層面及環境層面，網路心理層面包含了六項網路心理特性(匿名性、不可見性、非同步性、自我投射、解離的想像認知及階級權力最小化)及去個人化，社會層面則是採用了社會影響(主觀規範、描述性規範)，環境層面我們則是用遏止理論(內在遏止、外在遏止)來做衡量。本研究提出了一個創新的模式能夠彌補以往研究去抑制化行為上的不足。
本研究於台灣收集了530份網路使用者的有效樣本來驗證本研究的假說，結果顯示匿名性對於去個人化及去抑制化行為有顯著的影響。而非同步性及解離的想像認知對去抑制化行為則是有直接顯著的影響。在社會影響方面，結果顯示主觀規範比描述性規範對於去抑制化行為有更加顯著的正向影響，此外，在遏止理論方面，我們發現內在遏止可以有效地降低人們的的去抑制化行為，但外在遏止則無。
總而言之，本研究提供了學術界及實務界一個實證的結果，了解到底哪些因素確實會導致人們的去抑制化行為。同時我們也建立的一個創新的觀點，發現社會影響及遏止理論對於去抑制化行為是存在著交互作用的。

Computer-mediated communication (CMC) has since been found to have a correlation with uninhibited behaviors among users. Many of the human behaviors are less restraint to use rude or threatening language, leashing harsh criticisms, venting anger or hatred online, we called this phonemes ”Toxic online disinhibition effect. ”
Our empirical study tried to integrate psychological dimension, social dimension, and environment dimension －six internet psychological characteristics(dissociative anonymity, invisibility, asynchronicity, solipsistic introjection, dissociative imagination, and minimization of status and authority), deindividuation, social influence(subjective norm and descriptive norm), and containment theory(inner containment and outer containment)－ to propose an innovative model which can make up for deficiencies in previous studies of the toxic online disinhibition effect.
Data was collected from 530 internet users in Taiwan to test our hypothesis. The result shows that dissociative anonymity have significant impact on deindividuation and toxic disinhibition. In addition, asynchronicity and dissociative imagination have directly effect on toxic disnhibition. Besides, in social influence, we found that subjective norm is a stronger predictor of toxic disinhibition than descriptive norm. Moreover, in containment theory, the result shows inner containment can effective reduce toxic disinhibition but outer containment not.
To sum up, this study can provide academics and practical side empirical evidence that what factor would cause toxic disinhibition and give an innovation view regarding social influence and containment theory have relationship on toxic disinhibition.
