| Psychological safety is the basic psychological need of people, and plays important role on the individual survival and the development. For individuals, lack of psychological safety can reduce the individual psychological health level and effect of interpersonal trust, and for groups, lack of psychological safety can effect social stability and reduce social trust. The present situation of university students’social trust is not optimistic, and the social trust needs to be paid more and more attention. University students are the future builders and successors, and cultivating their social trust is important. Their social trust has an important influence on their development and social harmony. On the basis of psychometric theory, we drawn up standardized questionnaire "University Students’ Psychological Insecurity Questionnaire", then we made large sample survey with it, in order to investigate the the effect of psychological insecurity of social trust. The results are as follows:1. University students’ psychological insecurity includes 5 factors, such as anxiety and panic, escaping and avoiding, irritability and hyperactivity, the general sense of insecurity, self troubleshooting. The internal consistency reliability of the total questionnaire is 0.978; the internal consistency reliability of the factors are:0.955. 0.940.0.901ã€0.884 and 0.678. The fit index of confirmatory factor analysis are: x2/df=2.85,NFI=0.94, RFI=0.94, IFI=0.97, CFI=0.97, RMSEA=0.076; The criterion validity with the anxiety dimension, which is a dimension of intimate experience questionnaire, is 0.509; We carried out tests on some people, a month later the same tests were carried on them, there is no significant difference between two tests, which illustrate the retest reliability is good.2. The degree of the psychological insecurity of university students is in the low middle level. There is a significant sexual difference in the irritability and hyperactivity, and there are significant disciplinary differences in the anxiety and panic, escaping and avoiding, irritability and hyperactivity, general sense of insecurity, self troubleshooting.3. There is a significant negative correlation between psychological insecurity score and its 5 factors and social trust score and its 2 factors. The general sense of insecurity can predict social trust score and institutional trust, and the general sense of insecurity and irritability and hyperactivity can predict trust in others.4. The difference of psychological insecurity levels causes difference social trust levels, specifically, high level of psychological insecurity causes low level of social trust,and low level of psychological insecurity causes high level of social trust. |
