BACKGROUND: The psychological researches on undergraduates popularly believe that status of mental health of undergraduates can be worried.OBJECTIVE: To investigate the relationship between personality and mental health of undergraduates in Henan province, and analyze the feasible value of developing mental health education effectively.DESIGN: Sampling investigation.SETTING: Department of Health Administration, Henan Medical College for Staff and WorkersPARTICIPANTS: 1 128 students from 3 university and colleges in Henan province, whose majors were agriculture, medical science, sciences,literal arts, arts and physical education, etc., were enrolled randomly in this study between April and June 2001.METHODS: Group test was performed in 1 128 students from higher learning schools of Henan province test with Eysenck Personality Questionnaire (EPQ) [including 4 dimensions: Extraversion (E), Neuroticism (N),Psychoticism (P), and Social Desirability (L)] and Symptom Checklist90(SCL-90) (90 items, 9 dimensions).MAIN OUTCOME MEASURES: ① Comparison of personality characteristics between undergraduates and national norms. ② Classified comparison of personality characteristics of undergraduates. ③ Relationship between personality characteristics and mental health of undergraduates.RESULTS: Incomplete questionnaires were excluded, and 1 100 qualified questionnaires were collected. ① Comparison of personality between undergraduates and national norms: Scores on N and L of EPQ in male undergraduates were higher significantly than those of the national norms (5.47 ±3.13,4.53 ±3.11 ;4.99 ±2.47,4.50 ±2.59,P ＜ 0.001 ).Scores on N, P and L of EPQ in female undergraduates were all higher remarkably than those of the national norms (2.97±1.71,2.68±1.82;5.68±3.08,4.97±2.96;5.32±2.46,4.74±2.48,P ＜ 0.05-0.001). ②Classified comparison of personality in undergraduates: There were obvious differences on the 4 dimensions of EPQ in students of 6 different specialties (P ＜ 0.05-0.001 ). Scores on P in agricultural students were the highest (3.44±1.97); Scores on E in students of physical education were the highest (8.27±2.45), while scores on N in literate arts students were highest (5.99±3.24). Male students'scores on L were lower markedly than female students'(4.99±2.47,5.32±2.46,P ＜ 0.05).Scores on E in students from cities were lower significantly than those in students from countrysides (7.54±2.73,7.93±2.63,P ＜ 0.05). Between lower grade (freshman year and sophomore year) and higher grade (junior year and senior year), only scores on L in the former were high er significantly than those in the latter (5.42±2.44,5.01±2.48,P ＜ 0.01 ).Moreover, scores on E in student cadres were higher apparently thanthose in non-student cadres (8.42±2.61,7.42±2.68,P ＜ 0.001). ③Relationship of personality and mental health in undergraduates: E and L of personality dimension in undergraduates had obviously negative correlation with every factor of SCL-90 (P ＜ 0.01-0.001 )while N had significant positive correlation with every factor of SCL90 (P ＜ 0.001),and P had significant positive correlation with somatization, hostility,phobic anxiety and paranoid ideation (P ＜ 0.05-0.01 ).CONCLUSION: Personality of undergraduates have extremely close internal correlation with their mental health. Introversion, emotional instability and psychoticism of personality of undergraduates have side effects on their psychological health. There are some differences of personality characteristics in different specialty, sex, grade, native place (city or countryside),cadre or non-cadre students.

Objective To evaluate medical students′ achievements of studying through the practical base website for humanistic quality education. Methods Totally 61 students from school of nursing and 135 students from the first clinical medical college of Southern Medical University in Guangzhou were organized as volunteers. They were divided into the intervention group and the control group (98 people per group) in completely random method by the Random Number Generators of SPSS 20.0. With a two-month experiment, the humanistic knowledge scores and humanistic caring ability scores of these two groups were investigated by the Humanistic Knowledge Test Paper and the Caring Ability Inventory. And the learning effects of the website by the intervention group was evaluated with the self-designed questionnaire. Results There was no significant difference (P>0.05) between students in the intervention group and the control group when it came to general information. Before the experiment, the score of humanistic knowledge test paper, the total score of caring ability inventory, the score in the dimension of cognition, patience, and courage of the intervention group were 6.29 ± 0.58, 172.40 ± 10.00, 58.98 ± 4.22, 51.56 ± 5.22, 61.86 ± 6.40, the scores of the control group were 6.36 ± 0.63, 172.65 ± 13.49, 59.31 ± 4.05, 50.83 ± 6.56, 62.52 ± 7.28, there were no significant differences between the two groups (all P>0.05). After the experiment, the score of humanistic knowledge test paper, the total score of caring ability inventory, the score in the dimension of cognition and courage of the intervention group were 7.82± 0.62, 182.34 ± 12.78, 65.04 ± 9.12, 65.17 ± 6.58, the scores of the control group were 6.37 ± 0.60, 170.73 ± 8.92, 58.29±5.61, 62.36±6.90, there were significant differences between the two groups (t=2.92-16.67, all P<0.01). The scores in the dimension of patience of the intervention group and the control group were 52.12±3.60 and 51.02±4.34, and there was no significant difference (t=1.94,P>0.05). As shown by the evaluation made by students in the intervention group about the learning effect of the website, the average score was the highest in the field of skills (3.95 ± 0.58), followed by the cognitive field (3.92 ± 0.46) and emotional field (3.75 ± 0.66). Most of the respondents believed that web-based learning could deepen students′ understanding of humanistic quality education (4.13 ± 0.57), independent web-based learning could strengthen the application of online resources (4.06±0.59) and students could master communicative skills required in different situations through web-based learning (4.05 ± 0.58). Conclusions Students are satisfied with the practical base website for humanistic quality education, the website has rich learning contents and can improve students′ interests and motivation. Through web-based learning, humanistic knowledge and humanistic caring ability of students can be improved to some extent. But the website is still in development, it needs an evaluation indicators system in order to do further research for all application effects of the website.
