初中生网络成瘾生物心理社会预测模型的前瞻性研究

Internet Addiction Disorder (IAD) seriously affects the addicts' physical and mental health. While there is no mature therapeutic measure of IAD up to now. Under the circumstance, prevention of IAD is unquestionably the most effective way to reduce the harm from IAD. Accordingly, it is of great realistic significance to research the multiple risk factors of IAD to guide early intervention of IAD. Current relevant studies have some shortcomings such as sigle research angle and lack of combination of factors' effect. In addition, the greatest flaw is that the research evidence is not convincing enough. In this study, the subjects will be from the local junior high school students characterized by active network behaviors, nested case-control design will be applied and epidemiological survey will be combined with Event-related Potentials (ERP) and laboratory testing techniques such as Polymerase Chain Reaction (PCR) and High Performance Liquid Chromatography (HPLC). Additionally, we will use multiple regression analysis and Structural Equation Modeling (SEM) to explore the influential factors and the interactions among these factors in biology field, psychology field and sociology field and integrate these three views to construct a bio-psycho-social predicting model of IAD. The results of this study will provide scientific theoretical basis for the multi-aspect control and prvention of IAD.

网络成瘾严重损害青少年身心健康，目前国内外尚无比较成熟的网络成瘾干预方法。在此背景下，预防无疑是控制网络成瘾危害的最有效途径！因此，研究青少年网络成瘾的多重危险因素，从而指导网络成瘾的病因学干预具有重要的现实意义。现有的相关研究除存在研究视角单一、因素作用未能系统整合等不足外，最突出的缺陷是缺乏足够论证强度的研究证据。本项目拟采用巢式病例对照研究设计，以网络行为活跃的初中生群体为研究对象，结合流行病学调查、事件相关电位（ERP）技术及多聚酶链反应（PCR）、高效液相色谱（HPLC）等实验室检测方法，同时利用多元回归、结构方程模型等统计分析方法，从心理学、社会学、生物学等多领域探析网络成瘾发生的影响因素及其交互作用，并把三种观点整合成解释网络成瘾发生的生物-心理-社会多元化预测模型。本研究将为制定多方位的青少年网络成瘾预防控制策略和措施提供科学依据。
