Research On The Structure Model And Classification Model Of Depression And Anxiety Of College Students

Nowadays,the psychological situation of college students is arousing more and more attention in the society.They face a variety of pressures will appear in varying degrees of bad psychological emotion,especially depression and anxiety.It is a hotspot in psychology and computer science to analyze which factors are related to college students' depression and anxiety,and using data mining technology to analyze the collected psychological data.The research work in this paper mainly reflects the following three aspects:Firstly,this paper establishes a structural equation model of the relationship between potential variables with depression and anxiety.Structural equation model can effectively analyze the relationship between different potential variables.Most of the previous studies examined the effects of single factors on depression and anxiety.The structural equation model presented in this paper demonstrated the interaction between internal and external factors to depression and anxiety,better to demonstrated the relationship between different psychological variables and how these relationships work together to better explain the mechanism of depression and anxiety in college students.Secondly,by the brain functional imaging technique to analyzed the different between the brain functional state of the healthy subjects and the depression subjects and the anxiety subjects.It was found that Anxiety and depression can produce coupling effects.Depressive emotion could inhibit the function of the prefrontal cortex and basal nucleus,these brain regions are associated with brain reward circuits and the persistently low activity state of the brain reward circuit may be a major cause of depressive emotion;In addition,depressed subjects brain and temporal lobe and emotional related brain area is more excited,this may be related to the majority of depressed subjects are sentimental;prefrontal part of the brain activity decreased and the brain prefrontal is related to cognitive reasoning,planning strategies and working memory,which also shows a sense of depression affect cognition Function.To some extent,anxiety enhance the metabolism of brain-related brain areas and these high metabolic brain regions jointly lead to the occurrence of anxiety.Thirdly,this paper established a classification model of depression and anxiety based on psychological characteristics.Collecting 210 students psychological data based on the psychological on-line evaluation system and taking correlation analysis,by using the decision tree in data mining to establish the classification model of college students' anxiety and depression.Providing a valuable reference for the evaluation of depression and anxiety of college students based on psychological characteristics.
