Objective:To investigate the relationship among five personality factors, negative life events and suicidal tendency of college students, so as to provide reference for college students' suicide prevention.Methods:A cross-sectional survey was conducted among 885 college students in Xi'an city, Shaanxi province. A comprehensive college, a science and engineering college and a liberal arts college were selected respectively. Three questionnaires were applied to all subjects, including big five personality questionnaire, life event questionnaire and scale of adolescents' suicide tendency. Hierarchical regression model was adopted to analyzed the relationship of big five personality traits, negative life events and suicide tendency. Pearson correlation analysis and mediating effect test were conducted by using SPSS 20.0 software.Results:There was no significant interaction between gender and negative life events on suicidal tendency ( β=-0.03, t=-0.96, P>0.05). Conscientiousness( β=-0.12, t=-4.06, P<0.01), neuroticism ( β=0.24, t=7.54, P<0.01), agreeableness( β=-0.15, t=-3.65, P<0.01), extroversion ( β=-0.27, t=-8.56, P<0.01) and openness ( β=-0.12, t=-3.38, P<0.01)in Big Five personality had significant moderating effect on the relationship between negative life events and suicidal tendency. High conscientiousness, high agreeableness, high extroversion and high openness had protective effect on the relationship between negative life events and suicidal ideation. High neuroticism was a risk factor of the relationship between negative life events and suicidal tendency. Conclusion:The five factors of personality are closely related with negative life events and suicidal ideation. The five factors of personality can regulate the relationship between life events and suicidal tendency.

Objective: To explore the characteristics of cognitive processing over time in recognition of different emotional faces in patients with depression. Methods: Totally 29 patients with depression(patient group) and 30 normal control (control group)were selected.Subjects freely viewed positive, sad, threatening and neutral facial stimuli.Eye movement data were collected during the process of watching, and the differences of attention bias in time when the two groups of subjects recognized the four emotional faces were compared.The temporal variation trend of attention between the two groups was analyzed. Results: There was no significant difference in the fixation duration between the patient group and the control group in 0-2 s((10.39±1.83)ms, (9.63±1.28)ms), 2-4 s((12.61±2.34)ms, (11.21±3.00)ms), 4-6 s ((12.26±3.11)ms, (10.47±4.06)ms)(all P>0.05). Within 6-8 s((12.64±3.42)ms, (8.90±4.02)ms), 8-10 s((12.55±4.19)ms, (9.36±4.02)ms), the fixation duration in the patient group was significantly longer than that in the control group (P<0.01). The fixation time of the positive faces in the patient group in 0-2 s ((12.07±2.65)ms, (14.50±3.54)ms), 2-4 s((10.69±3.26)ms, (14.66±5.25)ms), 4-6 s((10.11±4.24)ms, (15.43±8.02)ms), 6-8 s((9.39±5.12)ms, (16.88±9.60)ms), 8-10 s ((9.45±4.94)ms, (16.63±10.15)ms) was significantly lower than that in the control group (all P<0.01). Conclusion Patients with depression tend to pay attention to negative stimuli in the later stage of cognitive processing, while the attention to positive stimuli decreases in the early stage of cognitive processing.Cognitive processing of emotional stimuli in patients with depression is manifested as increased attention duration of negative stimuli and decreased attention duration of positive stimuli.

ObjectiveTo verify whether the three different framing effects distinguished by Levin still exist in imitatively medical situation.MethodsEstablished medical decision making problems concerning doctor evaluation,medical compliance and treatment options selection.All these problem were described in the gain and loss frames.300 volunteers were randomly assigned to six groups.Every volunteer completed 2 decision making problems and evaluated their degrees of certainty.ResultsIf doctors were described in valid number,people tended to make more positive evaluations than described in invalid number( x2 =32.09,P ＜ 0.01 ).If treatment options were described in survival rates,people tended to choose adventure option of long-term benefit,otherwise people tended to choose conservative option of short-term benefit( x2 =25.92 P ＜ 0.01 ).If doctors' advices were respectively described in damaging or beneficial frames,the former one has better compliance (x2 =11.07,P ＜0.01 ).Parts of the deferences between the decision making confidence of choosing the adventure or conservative options were significant ( t attribute,positive =3.84,P ＜ 0.01 ; t goal,negative =6.44,P ＜ 0.01 ; t risky,positive =6.57,P ＜0.01 ).People were likely to be more confident with these options conforming to the framing effect.Conclusion-Framing effect exists in imitatively medical situation.

Objective To compare the cognitive difference of subjects'responses to the same visual stimuli under two different priming conditions,and to discuss the influence of inversion effect and configural changes upon facial recognition.Methods Priming pattern was employed,and subjects were induced to recognize the same stimuli as schematic faces or three English letters under different priming conditions.The participants'accuracy and reaction times were compared in two priming conditions. Results Participants'accuracy of the comparison stimuli in facial priming condition decreased significantly by inversion effect((79.03±10.53)%vs(89.43±9.98)%,P<0.01);reaction times of priming stimuli and comparison stimuli were delayed by inversion effect significantly((3720.40±607.71)ms vs(2998.33±544.02)ms,(3521.80±1038.20)ms vs(2750.87±867.13)ms,P<0.01),and there was no influence of inversion effect upon the reaction times of English letter stimuli(P>0.05).Correlations of accuracy to reaction times reached no significant difference under two conditions.Conclusion Priming effect make sense in the cognition,and there was a priming stage before the facial configuration.Inversion effect shows up in the face priming condition,and vanish in the English letter priming condition,which demonstrate the importance of configuration and inversion effect in the facial cognition.What's more,such effect can't be explained by the changes of cognitive difficulty.

Objective To explore the relevant factors for job burnout of female reserve duty soldiers in parade training.Methods Maslach burnout inventory-general survey(MBI-GS),Eysenck personality questionnaire (EPQ),coping pressure style questionnaire,self rating social adaptation and will power test were conducted in 380 female reserve duty soldiers in parade training.Results ①The results showed that the score of the job burnout in female reserve duty soldiers in parade training was in middle level.The scores was 12.83±5.28:5.86±3.90;23.28±6.18,respectively.②There were some relevant factors of job burnout and the significant correlation existed between job burnout of female reserve duty soldiers and coping pressure styles,personality,social adaptation and will power(P<0.01).③These factors could significantly predict job burnout(Standardized βwas 0.264,0.186;0.331,-0.161,-0.206,-0.144;0.391,0.179,0.199,-0.164).Conclusion To prevent the job burnout of female soldiers,it should be taken seriously about building up of their character,improving social adaptation and enhancing their will power.

Objective To analysis the relationship among coping styles,personality and mental health of female reserve duty soldiers in parade training,and built a path model on them.Methods Coping style questionnaire ,self check list(SCL-90) and Eysenck personality questionnaires were administered to 264 female reserve duself-blame( r=0.194) effected mental health directly.Self-blame(r=0.230) ,retreat( r=0.197) and illusion( r = 0.322) predicated mental health indirectly by the mediation of neuroticism.Conclusion Coping styles can influence mental health directly,and neuroticism is a mediation variance between coping styles and mental health.

Objective To explore the relationship between schizotypal personality proneness and intelligence .Methods 1905 subjects were tested by Chinese Soldier Personality Questionnaire(CSPQ).According to the results of CSPQ,the subjects were divided into high-risk subjects and normal ones.The Words Reasoning Test, the Arithmetic Reasoning Test and the Assembling Test were used to evaluate the intelligence,and the scores of these tests were compared between the two groups.Correlation coefficient between schizotypal personality proneness and intelligence was calculated.Results The scores of the Words Reasoning Test,the Arithmetic Reasoning Test and the Assembling Test in high-risk subjects were significantly lower than those in normal ones((87.83±18.42)VS(101.37±13.48),P<0.01;(91.74±14.26)vs(101.65±14.62),P<0.01;(87.70±18.82)VS (101.73±14.26),P<0.01).Schizotypal personality proneness was significantly correlated with the scores of intelligence(r=-0.39,P<0.01).Conclusion Lower intelligence level is found in the group with schizotypal personality proneness.Intelligence is correlated with schizotypal personality proneness.

Objective To study the relationship between psychological health and social support and coping style in general hospitals. Methods 756 nurses from 3 general hospitals were enrolled by cluster sampling and were investigated by Symptom Checklist 90(SCL-90),Social Support Rate Scale(SSRS)and Simplified Coping Style Questionnaire(SCSQ).The investigation results were analyzed. Results The general level of psychological health of nurses was not optimistic with a positive rate Of 37.04％. The somatizatlon factor of the head nurses was different from that Of normal nurses. Significant difference existed in the following aspects such as somatization, depression and terror factors between night shift nurses and day shift nurses. Relativity could be seen between social support and coping style and psychological health. Conclusion Hospital managers should attach importance to the psychological health of nurses. At the same time they should supply positive social support and instrucitons of coping style to improve the general level of psychological health.
