2592例大学生人格诊断问卷(PDQ^(+4))测试结果分析

Personality Disorders Detected by PDQ^(+4)in Under-Graduate Students

目的 :用人格诊断问卷 (PDQ+ 4)调查大学生人格障碍阳性率 ,探讨PDQ+ 4在特殊群体中的适用性。方法 :以PDQ+ 4问卷为工具 ,按照整群抽样的原则调查综合大学大学生 2 5 92人。结果 :大学生样本PDQ+ 4总分为 2 9 3 2± 12 0 4;十二项人格障碍分量表分 (除分裂性、回避型、强迫型外 )都普遍高于国内普通人群 ,样本比较差异有显著性 (P <0 0 0 ) ,各分量表得分的百分位显示在P90、P95位的得分普遍高出PDQ+ 4原量表划界分 ;在性别差异上 ,男性在分裂型和自恋型上分量表分较女性高 (P <0 0 0 ) ,女性在回避型、边缘型和依赖型上高于男性 (P <0 0 0 ) ,但总分上无显著性差异 ;通过因子分析提取了三个因子 ,分别为因子I -神经质 ,因子II-冲动性特质 ,因子III -精神质。结论 :以PDQ+ 4筛查大学生人格障碍 ,所得阳性率高于普通人群样本 ;该问卷的某些条目和原划界分不适合本研究样本 ,提示在用于我国文化背景时需进一步修订。

Objective:To investigate the personality characteristics and the positive rate of personality disorders (PD) among under graduate students and to explore the adaptability of PDQ +4 in special cluster of Chinese culture Method:For screening personality disorder, personality diagnostic questionnaire-4+(PDQ +4 )was administrated to a sample of 2592 students of two universities in Hunan and Shandong province Result:Among 2592 students, the mean of total PDQ +4 scores was 29 3±12 0;the subscales for different type of PD (excluding schizoid, avoidant, obsessive-compulsive)of PDQ +4 were higher than normal sample in China(P<0 00); the results of Percentile showed that the scores of all subscales were higher at the points of 90% and 95% than cut-off scores of PDQ +4 Three factors were abstracted by factor analysis The loading of three factors were very consistent with what was originally proposed in the theory of test construction Conclusion:The screening positive rate of personality disorders among under graduate students is higher than normal sample in China The items of PDQ +4 need to be adapted when applied in Chinese culture (especially in non-clinical clusters) Factor analysis shows that structural validity of PDQ +4 is high
