近年来，青少年网络成瘾的人数逐年增多，网络成瘾严重影响青少年的身心健康，因此，关注青少年的网络成瘾非常有必要。在诸多网络成瘾的影响因素中，亲子依恋备受关注，但对于亲子依恋如何影响网瘾的机制方面关注较少。亲子依恋可以通过各种因素影响青少年网络成瘾，其中感恩是一个重要的因素，感恩作为一个积极情绪能够建构青少年的人际资源，从而减少网络成瘾的风险。因此本研究期望探讨亲子依恋、感恩与网络成瘾三者之间的关系为社会工作干预青少年网络成瘾提供干预视角，并对干预方案的制定提供一定的指导。

本文对2419名农村初中生进行问卷调查，采用亲密关系体验-关系结构量表，感恩问卷以及网络成瘾（Internet Addiction Test）问卷对变量进行测量，描述了初中生亲子依恋、感恩和网络成瘾的特点，探讨了亲子依恋与网络成瘾的关系，以及感恩在亲子依恋与网络成瘾之间的中介作用。主要研究结果如下：

第一，农村初中生亲子依恋、感恩、网络成瘾存在人口学差异，具体表现为（1）在亲子依恋方面，女生、父母均在家的学生、家庭经济状况较好的学生、父母受教育程度较高的学生、亲子信任依赖程度较高，家庭经济状况较好的学生亲子回避焦虑程度更低；初三学生亲子信任依赖程度较低，亲子回避焦虑程度较高。（2）在感恩方面，女生、初一学生、只有父亲在家的学生、家庭经济状况较好的学生感恩水平较高。（3）在网络成瘾方面，家庭经济状况贫穷的学生、母亲受教育程度较低的学生网络成瘾程度较高；初中生的性别、留守情况、年级、父亲受教育程度网络成瘾程度没有显著差异。

第二，亲子依恋中的亲子信任依赖能够显著负向预测青少年网络成瘾，亲子回避焦虑能够显著正向预测青少年网络成瘾。

第三，感恩在农村初中生亲子依恋与网络成瘾之间起部分中介作用，即亲子依恋通过提高感恩水平从而降低青少年网络成瘾风险。

 根据研究结果，本文提出了立足已有网瘾干预方法，发挥社工优势；以家庭为中心，针对需求提供个案服务；开展多类型小组的社工建议。

In recent years, the number of adolescents with Internet addiction has been increasing year by year. Internet addiction seriously affects the physical and mental health of adolescents, so it is necessary to pay attention to adolescents' Internet addiction. Among the many factors influencing Internet addiction, parent-child attachment has received much attention, but less attention has been paid to the mechanisms of how parent-child attachment affects Internet addiction. Parent-child attachment can influence adolescent Internet addiction through a variety of factors, with gratitude being an important factor, as a positive emotion that can construct interpersonal resources for adolescents, thereby reducing the risk of Internet addiction. This study therefore aims to explore the relationship between parent-child attachment, gratitude and Internet addiction to provide an intervention perspective for social work interventions on adolescent Internet addiction and to provide some guidance for the development of intervention programmes.

In this paper, a questionnaire survey was conducted on 2419 rural junior high school students, using the Intimacy Experience-Relationship Structure Scale, the Gratitude Questionnaire and the Internet Addiction Test to measure the variables, describe the characteristics of parent-child attachment, gratitude and Internet addiction among junior high school students, explore the relationship between parent-child attachment and Internet addiction, and the mediating role of gratitude in the relationship between parent-child attachment and Internet addiction. addiction, and the mediating role of gratitude in the relationship between parent-child attachment and Internet addiction. The main findings of the study are as follows.

Firstly, there are demographic differences in parent-child attachment, gratitude and internet addiction among rural junior high school students, as shown by (1) in terms of parent-child attachment, girls, students with both parents at home, students with better family economic status, students with more educated parents, higher levels of parent-child trust dependency, and lower levels of parent-child avoidance anxiety among students with better family economic status; junior high school students have lower levels of parent-child trust dependency and The degree of parent-child avoidance anxiety was higher among junior students. (2) In terms of gratitude, the level of gratitude was higher among female students, first-year students, students with only their fathers at home, and students from better-off families. (3) In terms of Internet addiction, the level of Internet addiction was higher among students whose families were economically poor and students whose mothers were less educated; there was no significant difference in the level of Internet addiction among junior high school students in terms of gender, stay-at-home situation, grade level, and father's education level.

Secondly, parent-child trust dependence in parent-child attachment could significantly and negatively predict adolescent Internet addiction, and parent-child avoidance anxiety could significantly and positively predict adolescent Internet addiction.

Third, gratitude partially mediated the relationship between parent-child attachment and Internet addiction among rural junior high school students, i.e., parent-child attachment reduced the risk of adolescent Internet addiction by increasing the level of gratitude.

 Based on the findings of the study, this paper proposes social work recommendations that build on existing intervention methods for Internet addiction and bring into play the strengths of social workers; provide family-centred and needs-based case services; and conduct multi-type groups.
