In order to further explore the deep-seated mechanism of adolescent Internet addiction, this study screened out those adolescents with Internet addiction through Young's diagnostic questionnaires revised by Beard and Wolf and conducted multiple personality test questionnaires together with the negative control group, thus analyzing the psychological features of adolescents with Internet addiction. Subsequently, the Barratt Impulsivity Scale (BIS) and GoStop impulse test software are adopted to investigate the relationship between impulsivity and Internet addiction in the experimental group and the control group. It is concluded that the emotional behaviors of adolescents with Internet addiction all present obvious negative features, and Internet addiction is closely related to impulsivity
