Backgroundthe popularity of mobile phones not only brings convenience, but also brings dependence on mobile phones. This dependence is more obvious among college students who lack self-control and unsupervised. This paper studies and analyzes the physiological and psychological characteristics of mobile phone dependence from three aspects: mobile phone use time, browsing content and browsing repetition rate, and obtains the consequences of mobile phone dependence. Mobile phone addiction has brought a series of physical and mental reactions to college students, affecting their physical and mental health. Based on this, this paper starts with analyzing the manifestations of mobile phone addiction, and studies the causes of mobile phone addiction and the effects of anxiety and depression from the perspective of medical psychology.Subjects and MethodsBased on the limitations of the survey objects, the undergraduates in this paper only refer to the students of four-year applied research and applied undergraduate colleges. According to the subject type, undergraduates from grades 1 to 4 were selected for real-time observation and questionnaire survey to obtain sample data. Because the data obtained by different methods are very different, the second survey was conducted, and the data results are consistent. Therefore, the measurement results are weighted and summarized, and the real-time observation data is used as the basis of follow-up research. Study the correlation analysis of mobile phone dependence from the perspective of emotion regulation. In order to investigate the relationship between mobile phone addiction and emotion regulation ability, this study used the mental health locus of control scale to measure it. MHLC measures people's evaluation of the treatment effect from two poles. One pole reflects the view that mobile phone addiction should be responsible for the curative effect, that is, internal control, and the other pole reflects the role of the healer, that is, external control. MHLC is a self-assessment scale with 22 items and 6 insertion questions (no score). The original version included 61 items, which were tested in the group and simplified into the current scale through statistical processing. The scale is scored on a 6-point scale. 6 points represent the most external control and 1 point represents extreme internal control. In this way, the score range of the scale is between 22 (extreme internal control) and 132 (extreme external control).Resultsthe research shows that the main causes of group mobile phone addiction are external behavior and internal psychological disorder, but the causes of the two are the same, which come from material inducement, physiological inducement, psychological inducement and emotional inducement respectively. Among them, material inducement shows obvious external characteristics, physiological inducement and emotional disorder inducement show pathological characteristics, and psychological inducement shows internal characteristics. Based on the above analysis of mobile phone addiction, the higher education system needs physiological and psychological intervention.From the test results of the subjects, the test-retest reliability of a = 0.840 has not been reported. It showed that MHLC had little relationship with Rotter's I-E scale, but had a certain correlation with mental health origin scale (r = 0.40, P < 0.001). Further research suggests that gender and socio-economic status also have a certain impact on the score of this scale. Aggregation validity study shows that MHLC has high correlation with lenenson's I, P and C scales. Social expectation scale only has a certain correlation with CHLC subscale, r = -0.24, and has little relationship with IHLC and phlc. It shows that the test can show a good prediction potential of mobile phone addiction. However, so far, there is a lack of data on the validity of the scale, especially in those who are receiving treatment. At the same time, there is also a lack of reports on the comparison between the scale and other locus of control scales. Comparing the scale with special psychotherapy will be a very interesting research work.Conclusionthrough the analysis of inducements, the basic way to solve mobile phone addiction is obtained, that is, effective intervention is needed from both physiological and psychological aspects. Due to the particularity of the research object and research path, the research results have not been effectively tested. In addition, the social maladjustment of group mobile phone addiction is limited to the analysis of primary phenomena, and the research is not deep enough. From the perspective of medical psychology, according to the behavior and psychological performance of group mobile phone addiction, this study observed the pathological changes caused by it, explained the physiological trigger mechanism of mobile phone addiction, and put forward the countermeasures to solve mobile phone addiction. The above physical and psychological pressure will play a positive role in the correction of group physical and mental health in the future.AcknowledgementsThis research is based on the educational planning project of Zhejiang Province, “constructing the ideological and political ecosystem of college curriculum with internet thinking”.
