Objective: To explore the relationship between need for uniqueness and college students’mobile phone addiction, and the role of depression and maladaptive cognition for internet. Methods: A sample of 838 college students was surveyed with Need for Uniqueness Scale, Depression Scale, Maladaptive Cognition for Internet Scale and Mobile Phone Addiction Scale. Results: ①Correlation analysis showed that need for uniqueness, depression, maladaptive cognition for internet and mobile phone addiction were positively corelated with each other. ②Mediation modeling indicated depression and maladaptive cognition for internet had significant mediating effects between need for uniqueness and mobile phone addiction. The chain mediating effect of depression and maladaptive cognition for internet was also significant. Conclusion: Need for uniqueness not only directly affects mobile phone addiction, but also indirectly affects mobile phone addiction through the chain mediating effect of depression and maladaptive cognition for internet.

目的：探究独特性需要与大学生手机成瘾之间的关系，以及抑郁和网络非适应性认知在两者间的作用。方法：采用独特性需要问卷、GHQ-20量表的抑郁分量表、网络非适应性认知量表以及手机成瘾量表对838名大学生进行测查。结果：(1)相关分析显示，独特性需要、抑郁、网络非适应性认知、手机成瘾两两之间呈显著正相关；(2)中介效应检验表明，抑郁和网络非适应性认知在独特性需要和手机成瘾之间的中介作用均显著；且抑郁、网络非适应性认知的链式中介作用也显著。结论：独特性需要既可以直接正向预测手机成瘾，还可以通过抑郁和网络非适应性认知的链式中介作用间接影响手机成瘾。
