The Study Of Personality Among Different Stages Of Major Depression

Objective:To assess the influence of the symptoms to the measured personality and to assess the personality mode of Major Depression patients by investing the Eysenck Personality Questionnaire(EPQ)personality of patients among different MD stages.Methods:Collected 120 MD patients who visited the Psychiatry Department in the first Hospital of Shanxi Medical University from 2005.5 to 2007.3 and 93 healthy volunteers who were matched with the patients in gender,age at the same time.To collect the demography data including gender,age,educational level,occupation.Three personality dimensions (Neuroticism,Extraversion and Psychoticism)were assessed with EPQ,MD symptom severity were assessed with HAMD,the anxiety symptom severity were assessed with HAMA.Follow up the patients after being cured for 3months,to those whose HAMD and HAMA scores were less than 7,assess the EPQ again.Compare the EPQ personality among different stages and compare the EPQ personality between MD patients and healthy volunteers.The t-test, chi-square-test and correlation analysis were used for statistical methods.Results:1.Demography data:Use t-test and chi-square-test to gender,age,educational level between MD patients and normal controls,results show there were no statistical significance(P＞0.05) between two groups.2.Association study between EPQ personality and depression,anxiety symptom severity in acute stage of MD patients:There were positive correlation between HAMD and MD patients neurotic personality in acute stage(r=0.188,P=0.04),and there were no correlation between the P.E personality and MD patients HAMD scores(P＞0.05).There were no correlation between HAMA and EPQ personality(P＞0.05).3.To compare EPQ personality between MD patients catabasis and acute stage:There were no statistically significant difference of P personality between MD patients catabasis and acute stage;E scores(48.32±10.83)were obviously higher than acute stage(45.79±11.36)(t = -2.152, P =0.034),N scores(56.40±10.74)were obviously lower than acute stage(60.60±11.20)(t = 3.448,P =0.001).4.To compare EPQ personality between MD catabasis and healthy volunteers:P scores in MD catabasis(51.55±9.07)were obviously higher than healthy volunteers(46.51±8.23)(t = 4.385, P =0.000),E scores in MD catabasis(48.32±10.83)were obviously higher than healthy volunteers(55.44±9.92)(t = -4.663,P =0.000).N scores in MD catabasis(56.40±10.74)were obviously higher than healthy volunteers(44.36±10.47)(t =7.800,P =0.000). Conclusions:1.MD symptom may effect the personality measurement obviously.2.There are significant differences between personality measured in MD catabasis and that in acute stage.3.MD patients in catabasis show high psychoticism,high nervousness and introversion personality.4.We should assess the personality of MD patients after the symptom being controlled.
