The Distributing and Characteristic of Students' Personality Disorder Problems in an University

Objective: To achieve an in-depth knowledge of personality disorders prevalence features in the university students groups. Methods: Personality Diagnostic Questionnaire-4 + (PDQ-4+) was administered to a sample consisting of 3552 university students (including postgraduate and undergraduate) to investigate personality disorder (PD) subjects, and BPD subjects were diagnosed by Structured Clinical Interview for DSM-IV personality disorders (SCID-II). Results: 1) The undergraduates showed significantly higher than graduate students in the subscales for different types of PD (excluding schizoid) of PDQ-4+; 2) The males showed significantly higher than females in subtypes of paranoid, schizotypal, antisocial, narcissistic, com- pulsive-obsessive and passive-aggressive, and lower in subtypes of avoidant, borderline and dependent; 3) The results of Percentile showed that the scores of compulsive-obsessive and borderline were significantly higher at the point of 95% than cut-off scores of PDQ-4+; 4) According to the original classification, the positive rate of compulsive-obsessive was the highest, avoidant, histrionic, narcissistic, borderline followed, and schizotypal was the lowest; 5) The prevalence of BPD was 1.74% in the university students groups. Conclusion: There were differences in gender and art & science on some terms of PDQ-4+; the original clas- sification of PDQ-4+ is not suitable for university students, it needs to be adapted when applied.
