中文摘要：

本研究旨在考察母亲心理控制对青少年问题性网络使用（PIU）的直接和间接作用路径，以及这些路径是否受到性别的调节。以660名初中青少年为被试，要求其报告母亲的心理控制、非适应性网络认知以及问题性网络使用的情况。结果表明：（1）在控制了性别、年龄、家庭经济状况后，母亲心理控制对青少年PIU具有显著的正向预测作用；（2）非适应性认知在母亲心理控制与PIU之间具有部分中介作用。（3）母亲心理控制与PIU的直接和间接关系均未受到性别的调节。

英文摘要：

The purpose of the current study was to investigate ： 1 ） the relationship between maternal psychological control and adoles- cents＇problematic Internet use （PIU）; 2 ） whether this relationship was mediated by maladaptive cognition about Interact use; 3 ） whether there was a gender influence on the direct and indirect relationships between maternal psychological control and PIU. Participants were 660 middle school studenis （mean age = 14. 14 years, 364 females） recruited from a southern province in main- land China. During a school - based assessment, participants completed Maternal Psychological Control Questionnaire, Maladaptive Cognition about Internet Use Questionnaire, and Problematic tnternet Use Scale. Hierarchical linear regression analyses showed that： （ 1 ） after controlling for gender, age, and family economic conditions, psy- chological control was positively associated with PIU （fl = . 22, p 〈 . 001 ）. （2） Maladaptive cognition partially mediated the relation- ship between psychological control and PIU （the mediated effect accounted for 71.2% of the total effect）. （3） Males had higher levels of PIU than females. However, no significant mod~ating effects of gender was found on the direct （ including both overall and residual effects） or indirect （including the relationship between maternal psychological control and malgdaptive cognition as well as the relation- ship between maladaptive cognition and PIU） relationships between maternal psychological control and PIU. In conclusion, we build on and contribute to existing literature in several important ways. First, maternal psychological control is positively related to adolescents PIU, which is different from behavioral control. Even though psychological control is more popular a- mong Chinese parents than those of western countries, it is indeed a risk factor for adolescents development. Second, maladaptive cog- nition partially mediates the relationship between maternal psychological control and PIU
