Abstract:Objective To investigate whether there are any differences in the Eysenck personality characteristics between repeaters and non-repeaters and to further study the influencing factors, so as to provide a basis for further development of psychologically educational and instructional activities among the repeaters. Methods We randomly selected 106 repeaters and 221 non-repeaters from universities in Xuzhou City. General information questionnaire and Eysenck Personality Questionnaire (EPQ) were used to survey the 327 college students. Data were input with Epi Data 3.1, and were analyzed with SPSS19.0 software. Results EPQ test revealed that the difference in P dimension of Eysenck personality between the repeaters and the non-repeaters showed statistically significant difference (P<0.05). The students with higher score in P dimension were more inclined to stay down.Univariate analysis showed that there were statistically significant differences in the score of each EPQ factor in the repeaters with respect to 17 variables, such as whether or not being only-one-child, whether or not being from single parent family and whether or not having enough living expenses. Multiple regression analysis showed that the score of each EPQ factor of the repeaters was correlated with various factors, such as only-one-child familiy background, parental control, burden of study and social pressure. Conclusions Eysenck personality characteristics of the college repeaters in Xuzhou City display obvious particularity, and their mental health is affected by self-factors, school atmosphere, family environment, etc. Overall, the mental health of the college repeaters is poor, and the society should pay enough attention to them.
