Abstract
Objective To explore the correlation between the higher-order personality dimension(neuroticism) and the lower-order personality traits(alexithymia, dependence, self-criticism, perfectionism) in the sample of university students, and explore the effect of the higher-order personality dimension and lower-order personality traits to depression in the same sample. Methods A convenient sample of 563 university students from the two Universities College in Hunan province.These students were assessed with Center for Epidemiological Studies-Depression Scale(CES-D), Depressive Experiences Questionnaire(DEQ), The twenty-item Toronto Alexithymia Scales(TAS-20), Frost multidimensional perfectionism scale(FMPS) and neuroticism subscale in EPQ. Results (1)There were significant relationships between the total score of CES-D, each depressive symptoms and 10 personality factors, such as neuroticism, doubts about action and so on(The coefficients ranged from 0.105 to 0.569, P<0.05 or P<0.01). (2)Factor analysis and multiple linear regression on the neurotic showed that doubts about action, concerned over mistakes, difficulties identifying feelings(DIF), difficulties describing feelings(DDF), dependency, self-criticism and neuroticism belonged to the factor 1(the factor load coefficients ranged from 0.574 to 0.775). (3)Neuroticism can explained 32.3% variance of depression(Radj2=0.323), after 6 personality factors entered the regression equation, such as difficulties describing feelings(DDF), parental criticism and so on, the explained variance of depression increased to 43.2%(Radj2=0.432). Conclusion There are overlapping and interaction between personality traits which include self-criticism, dependency, difficulties describing feelings(DDF), difficulties identifying feelings(DIF), concerned over the mistakes and neuroticism personality dimensions. The depressed affect are effectively predicted by neuroticism which is a effectively predict factor of depression, personality traits included self-criticism, dependency, alexithymia and malajustment perfectionism have a gain function of depression base on the Neuroticism.
