The Role of Meditation in College Students' Neuroticism and Mental Health

Abstract A large number of empirical studies have found evidence that neuroticism is related to personality traits, but no one has integrated the relationship between neuroticism and mental health through meta-analysis. As a personality trait, neuroticism reflects the stable tendency of how individuals experience, feel, evaluate negative emotions and make corresponding behavioural responses. By means of meta-analysis, a preliminary dimension of neuroticism is constructed through an open questionnaire and literature review. On this basis, a preliminary neuroticism questionnaire for college students is compiled. The structural model of College Students' neuroticism questionnaire fits well, and has a high correlation with the neuroticism subscale of the simple version of Big Five Personality Questionnaire, which shows that it has a good structural validity. The positive orientation indicators of subjective well-being, life satisfaction and other mental health indicators were also selected. In addition, self-assessment indicators of physical health were selected. It was found that neuroticism was highly correlated with appeal indicators, indicating that the questionnaire of College Students' neuroticism had good validity.


Introduction
Contemporary college students shoulder the mission of building socialism with Chinese characteristics and realizing the great rejuvenation of the Chinese nation. Their mental health level is not only related to the stability and development of the future society, but also to the healthy growth of the next generation. Therefore, the mental health of college students has become an important topic in the fields of psychology, education, management, and economics. Research in these fields shows that the mental health of college students is affected by many factors, among which neuroticism is one of the important factors. The core feature of neurotic personality is the tendency to experience negative emotions. This tendency causes individuals to experience more negative emotions and less positive emotions, thus making neuroticism have a negative impact on mental health, manifested as neurotic personality is depression. Susceptibility factors for common mental disorders such as symptoms and anxiety disorders.
As researchers pay more and more attention to the mechanism of sound mental health, the relationship between contemplation and mental health has become a hot research topic. Personality and health are closely related.
Although in the final analysis, whether health changes personality or personality affects health is a "chicken or egg first" problem that puzzles psychologists, a large number of studies also reflect that personality and health are highly related. There have been four models about the relationship between personality and mental health: a certain personality may lead to a certain disease, and a certain personality may be caused by a certain disease. Personality may be a perceptual filter personality and illness feedback each other. Neuroticism is one of the universal personality dimensions. This dimension refers to a continuum from extreme emotional instability to emotional stability.
People with high neuroticism are highly anxious, moody and easily agitated. At the same time, people with low neuroticism have mild and slow emotional response, and are easy to recover calm, not easy to anxiety, stable and mild, and easy to self-restraint [1] .
Meditation is now regarded as important cognitive factors lead to depression, and is closely related to the individual's emotional state. When individuals in the social information processing, the meditation of cognitive style tends to lead to repeated thinking of subjective negative feelings, that more durable for depression, poor circulation, meditation and depression will ultimately affect the mental health of the individual. Random effect model should be used to calculate the average effect value [2] . The metaanalysis of the correlation coefficient between neuroticism and mental health of college students in China is shown in Table 1 below.

Neuroticism and intimacy
Neuroticism is not only closely related to depression and anxiety, but also to physical fitness. It is also closely related to 1 life satisfaction. Some studies have found that there is a significant negative correlation between neuroticism and life satisfaction [3] .  [4] . The meta-analysis of the correlation coefficient between introversion and extroversion and mental health of college students at home and abroad is as follows:

THE ROLE OF MEDITATION IN COLLEGE STUDENTS' NEUROTICISM AND MENTAL HEALTH
As an important risk factor in psychopathology, neuroticism is closely related to depression. It was found that all the diagnostic groups scored better in neuroticism.
Anxiety disorder had the closest relationship with neuroticism, followed by depression disorder, and substance abuse disorder had the weakest relationship. However, depression increased faster in high neuroticism individuals than in low neuroticism individuals. In short, the higher the neuroticism level of individuals, the more depressive emotions they experience, the higher the risk of depression, and the higher the risk of recurrence of depression after cure [5] . after controlling intermediary variables, the predictive effect of independent variables on dependent variables is significantly reduced [6] . If the independent variable predicts the dependent variable significantly after controlling the intermediary variable, there will be some intermediary effect. If the independent variable does not predict the dependent variable significantly after controlling the intermediary variable, there will be a complete intermediary effect.

Correlation analysis of depressive symptoms, neurotic personality and contemplation
The predictive effect of neurotic personality on depressive symptoms was significantly reduced.
The standardized regression coefficient of neurotic personality on depressive symptoms decreased from 0.601 before the introduction of mediating variables to 0.414 after the introduction of mediating variables, indicating that there was mediating effect [7] . Fitting degree between the constructed five-factor neuroticism structure model and the measured data. There are many fitting indexes for confirmatory factor analysis, such as chi-square freedom ratio_2/df, RMSEA of approximate error, GFI of goodness of fit, AGFI of absolute fitting index, CFI of comparative fitting index, PNFI and PCFI of simple fitting index. If 2/df is less than 5, the model fits well.
The closer RMSEA is to 0, the better RMSEA is to    There is also a close relationship between meditation and anxiety. The results show that meditation is significantly correlated with anxiety.
A sample of college students has been studied.
The results show that meditation, compulsive meditation and reflection are strongly correlated with anxiety. Meditation is not only related to anxiety, but also to social anxiety. Individuals with high meditation level will have more inadaptable negative thoughts, fewer problem solving behaviours, fewer Du will support and more social friction, resulting in a higher level of anxiety experienced by individuals. In order to investigate whether the scores of contemplation and anxiety of college students conform to the normal distribution, the distribution of the scores of contemplation and anxiety of college students is shown in Figure 2.
From the above figure, we can see that the total score of neuroticism and various dimensions of college students are basically low, which shows that the emotional stability of college students is better basically. From various dimensions, college students are more likely to experience anxiety [9]. It can be seen that the emotional stability of college students is basically good, and in terms of the tendency to experience negative emotions, anxiety is more than depression. To test whether the sample is normal distribution, the sample is generally tested by castrated P-P chart. As shown in Figure   3, the castrated P-P chart of the total neuroticism score of college students is as follows: From the graph, we can see that the normal distribution test of each dimension shows that the scores of each dimension also obey the normal distribution.  [10] . Therefore, reveal the relationship between meditation and life satisfaction, and put forward reference suggestions to improve individual life satisfaction. Stepwise regression analysis was carried out with the scores of neuroticism and subjective well-being as independent variables. The variance of 24.4% was explained.      satisfaction is relatively simple. This shows that neuroticism is a negative and rational trait, and the mechanism of its influence on negative health indicators such as depression and anxiety is complex, as shown in Figure   4. The impact on health indicators such as life satisfaction is relatively simple. The complex mechanism of neuroticism affecting health was discussed. It was found that the mechanism of neuroticism affecting negative health indicators such as depression and anxiety was complex, and the mechanism of neuroticism affecting health indicators such as life satisfaction was relatively simple [11] . This  Table 6.
From the above table, we can see that the fitted indexes of neuroticism and physical and mental health model are good, which shows that the model is reasonably constructed.
Meditation, that is, compulsive meditation and reflection, partially mediates the relationship between neurotic personality and depressive symptoms.

Conclusion
Contemplation is a complex mode of thinking.
With the deepening of deep thinking research, more and more researchers have carried out multi-level analysis on it, but our research in the field of contemplation is still in the preliminary stage. Existing contemplative research   Neuroticism not only has a direct impact on anxiety, but also has an indirect impact on
