Abstract

Resilience is one of the important indicators of mental health. It is the psychological characteristics of individuals to overcome difficulties and complete the process of positive adaptation under adversity and pressure. The research on resilience of college students has a direct help and guidance to improve the level of mental health of college students. This study adopts the Connor Davidson Resilience Scale (the Connor Davidson Resilience Scale), which is widely used in China Using spss19.0 and MATLAB to make principal component analysis and fuzzy comprehensive evaluation on the survey data, the results show that: (1) the weight of the three secondary indicators of resilience is tenacity (77.631%) > strength (16.364%) > optimism (6.005%); (2) According to the evaluation index system of resilience, the fuzzy comprehensive evaluation model is constructed from three dimensions of tenacity, strength and optimism. The coefficient of variation method is used to determine the weight of psychological indicators, so as to avoid the subjective arbitrariness brought by the subjective weighting method. Then, the secondary indexes are quantified, and a mathematical model is established to predict and measure the level of resilience; (3) The proportion of poor and very poor resilience of college students is 11% and 6% respectively, and the total is as high as 17%. This fully shows that the level of College Students' resilience is not optimistic, and it needs to arouse the positive attention of colleges and universities. (4) Resilience accounted for 77.631% of the weight of psychological resilience. Strengthening the training of College Students' psychological resilience is an effective way to improve the level of College Students' psychological resilience. (5) The proportion of poor college students with poor and very poor resilience is 48%, which is 31% higher than other college students. The resilience index of poor college students is 2.57, which is also significantly lower than 3.38 of other college students.
