Causes of Internet Addiction Most scholars believe that the causes of Internet addiction are complex and are the result of the interaction between the addicted individual, the network environment and the external environment in many ways. Internet addiction depends on both the susceptibility of adolescents to addiction and what the Internet itself can provide and the influence of the real social life environment. The former is the internal cause of addiction. The latter is the external cause of addiction. (I) The susceptibility characteristics of adolescents From adolescents’ own personality characteristics and psychological characteristics, they are in the stage of immaturity and instability of psychological development, and they are easily influenced by the external environment. If their communication with parents, friends and classmates in real life creates obstacles, it is easy to form a self-enclosed mentality. Turning to the virtual network to seek comfort and understanding, to satisfy their self-esteem and needs. Some teenagers pursue fun, lack of self-control, learning and difficult to achieve better psychological intervention for network addiction, many Gestalt psychotherapy and other methods, is a comprehensive achievement, and in the virtual network world, all the less than ideal are covered up, especially in those who can “make great progress” online games! In. Not only can you get a sense of accomplishment through upgrading. Can also get a temporary psychological balance. In addition, existing research has found. Personality trait factors are the internal psychological roots of adolescent Internet addiction. Those sensitive, depressed, vulnerable, suspicious, anxious, emotionally unstable, weak will, poor self-control, withdrawn, poor cognitive ability, lack of self-confidence, pessimism, escapism, low self-esteem, and low sense of achievement if the adolescents on the Internet, it is easy to lead to Internet addiction (b) the reality of the environment of the adolescents Internet addiction and the family environment School education environment has a lot to do with the fact that some parents are too spoiled children, all the things Some parents spoil their children too much and ask too many questions, leaving these teenagers in the rebellious stage without any space for themselves. This stimulates them to get rid of their psychological constraints through the Internet: some other parents are only concerned about their own careers and seldom communicate with their children. If the children turn to the Internet to seek comfort and become addicted to it, the Internet users may become more important than the real-life relatives and friends: there are also some families with poor family relationships or single-parent families. The child may have certain psychological and character defects, and these high anxiety, low self-esteem, depressed, and unclear self-concept adolescents are also more prone to Internet addiction. In terms of modern school education, the cruel college entrance examination system, heavy study pressure, and boring study life puts teenagers under great pressure, and they can release their inner anxiety and relieve pressure by surfing the Internet, but this also gradually causes their dependence on the Internet. (C) the network itself For the characteristics of the network, the theoretical model, that the network’s anonymity, convenience, escape from reality three major features lead to user addiction: also summarized the characteristics of the network. In general, the network’s high-tech, richness, openness, wide range, interactivity, indirectness, equality and other characteristics, bring a lot of convenience to the daily study and life of young students. This is what the real society can hardly provide and what adolescents need. It is because of these characteristics that it constitutes an irresistible attraction to adolescents, making it difficult for them to indulge in this virtual reality.
