Objective      To explore the personality characteristics of postgraduates from military university.       Methods      Eysenck Personality Questionnaire (EPQ) and symptom checklist 90 (SCL-90) were used to evaluate 1 536 military university postgraduates

and meanwhile

the military norms and military university student norms were chosen as controls. The personality differences in gender

age

educational level and grade were compared.       Results      (1) The psychoticism and neuroticism scores of the military university postgraduates were significantly lower than those of the military norms and the military student norms (P0.01)

while the introversion-extroversion scores were significantly higher (P0.01). The lie scores were higher than those of the military student norms but lower than those of the military norms (P0.01). (2) The psychoticism scores of male postgraduates were significantly higher than those of female postgraduates (P0.01)

but the neuroticism and lie scores of male postgraduates were significantly lower (P0.01). There was no statistical difference in the introversion-extroversion scores between male and female postgraduates (P0.05). (3) There was significant age difference in the psychoticism scores (P0.01)

and the psychoticism scores in the groups of 25-29 years old and 30 years old were higher than those in the group of 25 years old (P0.01). There was statistical difference in the introversion-extroversion scores between the groups of different ages (P0.01). (4) The psychoticism scores of doctoral candidates were significantly higher than those of the master candidates (P0.01)

but the introversion-extroversion scores of the doctoral candidates were relatively lower (P0.01). (5) The psychoticism scores of grade-2 postgraduates were significantly higher than those of grade-1 postgraduates (P0.05)

but the introversion-extroversion scores of grade-2 postgraduates were relatively lower (P0.05). (6) The psychoticism and neuroticism scores of the SCL-90-negative group were significantly lower than those of the SCL-90-positive group (P0.01)

and the SCL-90-negative group showed higher introversion-extroversion scores and higher lie scores (P0.01).       Conclusion      Military university postgraduates show more exocentric character and more stable emotion

and have obvious developmental characteristics in gender

age

level and grade.
