青少年时期是个体身心发展的关键时期，过度使用短视频的个体易短视频成瘾，会引起一系列心理、身体和社交上的不良后果。青少年对短视频的使用极其频繁，《2021年全国未成年人互联网使用情况研究报告》显示，我国初中生中经常使用短视频的比例为61.8%；一项对普通在校中学生的调查显示，在过去一周内使用抖音短视频平台的时间超过3小时的人数比例为16.7%。同伴是青少年短视频成瘾、手机成瘾等行为成瘾的重要影响因素，与同龄人越来越多的互动是青少年成瘾行为的主要原因。本研究重点探讨同伴关系和不良同伴交往这两个同伴系统中的关键变量对青少年短视频成瘾的协同影响作用及具体的作用机制。本研究采用短视频成瘾量表、同伴关系量表、不良同伴交往量表和错失恐惧量表进行测量，收集了广西省南宁市3所学校640名初中生的数据，其中男生359名，被试群体的平均年龄为14.24岁。使用描述统计、方差分析、回归分析、多项式回归和响应面分析等方法分析了初中生同伴关系和不良同伴交往对短视频成瘾的各自的影响和协同的影响作用，并进一步分析了具体的影响机制。研究发现：
（1）同伴关系显著负向预测青少年的短视频成瘾；不良同伴交往显著负向预测青少年短视频成瘾（不良同伴交往越多，青少年短视频成瘾倾向越高）。
（2）同伴关系和不良同伴交往协同影响青少年短视频成瘾。一致的情形下，相较于同伴关系差、不良同伴交往多的青少年，同伴关系好、不良同伴交往少的青少年短视频成瘾的倾向更低；不一致的情形下，相较于同伴关系差、不良同伴交往少的青少年，同伴关系好、不良同伴交往多的青少年短视频成瘾倾向更高；不良同伴交往对短视频成瘾的影响强于同伴关系的影响。
（3）同伴关系和不良同伴交往可以通过协同影响错失恐惧间接影响青少年短视频成瘾，错失恐惧起部分中介作用。

Adolescence is a critical period for individual physical and mental development. Individuals who use short videos excessively are prone to short video addiction, which cause a series of psychological, physical and social consequences. Teenagers use short videos extremely frequently. The "2021 National Research Report on Internet Usage of Minors" shows that the proportion of junior high school students who often use short videos in my country is 61.8%; a survey of ordinary middle school students shows that 16.7% of the individuals used Tik Tok for more than 3 hours within a week.
Peers are an important factor affecting adolescent short video addiction, mobile phone addiction and other behavioral addictions, more and more interactions with peers are the main reason for adolescent addictive behaviors. This study focuses on the combined effect and specific mechanism of peer relationship and deviant peer affiliation, the two important variables in the peer system, on adolescent short video addiction.
In this study, the Short video addiction Scale, Peer relationship scale, Deviant peer affiliation scale and Fear of missing out scale were used to measure, and the data of 640 junior high school students from 3 schools in Nanning, Guangxi Province were collected, including 359 male students. The average age of the subjects was 14.24 years old. Descriptive statistics, analysis of variance, regression analysis, polynomial regression and response surface analysis and other methods were used to analyze the respective and combined effects of junior high school students' peer relationship and deviant peer affiliation on short video addiction, as well as the influence mechanism. The study found that:
(1) Peer relationship significantly and negatively predicts short video addiction. Deviant peer affiliation significantly and negatively predicts short video addiction. The more Deviant peer affiliation is, the higher the tendency of short video addiction is.
(2) Peer relationship and deviant peer affiliation combined affect adolescent short video addiction. When two variables matched, compared with the situation of less deviant peer and good peer relationship, the worse the peer relationship and the more deviant peer, the higher the tendency of short video addiction. When two variables mismatched, compared with the situation of less deviant peer and poor peer relationship, the better the peer relationship and the more deviant peer, the higher the tendency of short video addiction. Besides, the influence of deviant peer affiliation on short video addiction is stronger than that of peer relationship.
(3) Peer relationship and deviant peer affiliation can indirectly combined affect adolescent short video addiction by the fear of missing out, the fear of missing out plays a partial mediating role.
