目的：探索在新冠疫情居家期间低年级儿童抑郁症状与网络游戏障碍症状的关联模式,为从相关抑郁症状着手干预网络游戏障碍提供靶点。
方法：采用整群抽样方式于2022年4月在保定市某小学低年级学生中入组667名,通过问卷星平台使用儿童抑郁量表（Children's Depression Inventory,CDI）和网络游戏障碍量表（Internet Gaming Disorder Scale,IGDS）评估其相应的症状。使用SPSS软件进行描述性统计分析、Mann-Whitney U检验,使用R软件进行网络模型构建、边权值评价和桥中心性分析。
结果：在低年级小学生群体中,CDI总分的平均值为6.7（4.3）,IGDS总分的平均值为13.6（6.1）,男生抑郁与网络游戏障碍总得分均显著高于女生。CDI不同因子分与IGDS条目得分均存在正相关,但关联模式不同;网络边权值的评估是准确的;桥预期影响的稳定性良好（相关稳定性系数=0.517）,其中快感缺失因子桥预期影响最高（桥预期影响值=0.240）。
结论：抑郁的快感缺失因子与网络成瘾症状有着更紧密的联系。当从抑郁症状的不同因子着手对网络成瘾症状进行干预时,以快感缺失抑郁因子为靶点可能对网络成瘾症状发挥更加广泛而有效的作用。
Objective: To explore the correlation patterns between depression and internet gaming disorder symptoms of lower-grade primary school students during the COVID-19 lockdown period, and to provide a target of psychological intervention for depression symptoms associated with internet gaming disorder.
Methods: A total of 667 lower-grade primary school students from Baoding city were enrolled by cluster sampling in April 2022 and were assessed with Children's Depression Inventory and Internet Gaming Disorder Scale via the Wenjuanxing online survey tool. The descriptive statistical analysis and Mann-Whitney U test were conducted by SPSS. R software was used to build the network model, evaluate edges, and analyze bridge centrality.
Results: In the lower-grade primary school students, the average of the total CDI score is 6.7 (4.3) and the average of the total IGDS score is 13.6 (6.1). The total score of depression and internet gaming disorder of boys are significantly higher than that of girls. Different CDI factor scores are positively correlated with IGDS item scores, but different correlation patterns are illustrated. There is a good accuracy of network edge weights. The stability of the bridge expected influence is ideal (correlation stability coefficient = 0.517), and the factor of anhedonia has the highest bridge expected influence (bridge expected influence=0.240).
Conclusions: Anhedonia factor is more closely associated with the internet gaming disorder community. When considering the intervention of different factors of depression to reduce the occurrence of internet gaming disorder symptoms, the anhedonic factor may play a more extensive and effective role.
