本研究基于最优独特性理论和网络成瘾的个人-情绪-认知-执行交互模型，考察独特性需要与大学生手机成瘾之间的关系以及焦虑和意志控制的链式中介作用。采用独特性需要问卷、GHQ-20量表中的焦虑分量表、意志控制量表以及手机成瘾量表对826名大学生(女生=526人，Mage=19.93,SD=1.38)进行测查。结果发现:(1)独特性需要与手机成瘾、焦虑呈正相关，与意志控制呈负相关;焦虑与意志控制呈负相关，与手机成瘾呈正相关;意志控制与手机成瘾呈负相关;(2)焦虑和意志控制在独特性需要和手机成瘾之间的单独中介作用均显著;且焦虑、意志控制的链式中介作用也显著。本研究的结果表明，独特性需要既可以直接与大学生手机成瘾产生联系，也可以分别经由焦虑、意志控制的中介作用、以及两者的链式中介作用与大学生手机成瘾产生联系。本研究的结果支持并拓展了I-PACE模型，并为手机成瘾的预防和干预提供了新的方向。

Based on the optimal distinctiveness theory and the interaction of the Person － Affect － Cognition － Execution model for internet addiction ( I － PACE) ，this study examined the relationship between need for uniqueness and mobile phone addiction of college students and explored its mechanism ( the chain mediating effect of anxiety and effortful control) ． In this study，826 college students ( Female = 526，Mage = 19. 93，SD = 1. 38) were tested by the Need for Uniqueness Scale，Anxiety Scale，Effortful Control Scale and Mobile Phone Addiction Scale． The results showed that : ( 1) Need for uniqueness was positively correlated with anxiety and mobile phone addiction，negatively correlated with effortful control; anxiety was negatively correlated with effortful control，positively correlated with anxiety and mobile phone addiction; effortful control was negatively correlated with mobile phone addiction; ( 2) Anxiety and effortful control had significant mediating effects between need for uniqueness and mobile phone addiction． The chain mediating effect of anxiety and effortful control was also significant． In conclusion，the results of this study suggest that the need for uniqueness can not only be directly associated with college students’ mobile phone addiction but also through anxiety，effortful control，and their chain mediating effect，respectively．The results of this study support and expand the I － PACE model and provide a new direction for the prevention and intervention of mobile phone addiction．
