中文摘要：

基于整体一交互作用模型，选取北京市某高校所有大一学生2511名为被试开展问卷调查，考察了大学生网络使用背景性渴求的特点及其与网络成瘾之间的关系，并就网络使用背景性渴求与同伴网络过度使用行为与态度对网络成瘾的交互作用进行了检验。结果发现：（1）与非网络成瘾大学生相比，网络成瘾大学生的网络使用背景性渴求更高，所感知到的同伴网络过度使用行为更多，同伴对网络过度使用的态度更积极；（2）网络使用背景性渴求各维度、感知到的同伴网络过度使用行为可正向预测大学生的网络成瘾；（3）背景性渴求中的积极结果预期与同伴对网络过度使用的态度对网络成瘾存在显著的交互效应：在低积极结果预期条件下，同伴对网络过度使用的态度可以负向预测网络成瘾程度，而在高积极结果预期条件下，同伴态度对网络成瘾的预测作用不显著。结论：外因在内因比较微弱的条件下发挥更为明显的作用。

英文摘要：

Based on the holistic-interactionistic model, a study examined the relationship between background craving （anticipation of positive outcomes, and relief from negative affects） and college students＇ Internet addiction, as well as the interaction effects among background craving, peers＇ Internet overuse behavior, and attitude towards Internet overuse on Internet addiction in college students. A sample of 2511 freshmen was recruited from a university in Beijing to fill out the questionnaire measures of background craving, perceived peers＇ Internet overuse behavior, attitude towards Internet overuse, and Internet addiction level. Results revealed that： （1） Compared to Internet non - addicts, Internet addicts among college students had much higher levels of background craving for Internet use, perceived more Internet overuse behaviors, and more positive attitudes about Internet overuse. （2） Background craving factors and peers＇ Internet overuse behavior could positively predict Internet addiction in college students. （3） An interaction effect on college students＇ Internet addiction was found between anticipation of positive outcomes and peers＇ attitude towards Internet overuse. In condition of low level of anticipation, peers＇ attitude towards Internet overuse could negatively predict college students＇ Internet addiction, whereas, the prediction effect didn＇ t exist under condition of high level of anticipation. Conclusion： The effect of external causes was more significant when internal causes were relatively weak.
