摘要
目的 :将人格障碍诊断问卷 (PersonalityDiagnosticQuestionnaire ,简称PDQ)第四版的中文版用于中国不同地区的普通人群及精神障碍人群 ,制定出国内初步常模并就其信度和效度资料进行研究。方法 :将人格障碍诊断问卷 (PDQ - 4 +)施测于国内 10个省市的 6 2 8例普通人群及 36 7例不同诊断的精神障碍患者。 4 9位被试间隔 2~ 4周重测。结果 :PDQ - 4 +的重测信度系数为 .5 0~ .80 (P <0 .0 1) ,分半信度指数为 .5 0~ .93,α系数为 .5 6~ .78。效度分析显示 ,精神分裂症组、情感精神障碍、神经症组及人格障碍组的各分量表分及总分均明显高于普通人群组 ,差异有极显著性意义 (P <0 .0 0 1) ;因素分析显示 ,12个分量表在 3个公因子上负荷分布与理论上的三个分群近似 ;以总分计算 ,PDQ - 4 +对人格障碍的诊断有较高的灵敏度和较低的特异度。结论 :PDQ - 4 +的中国普通人群的常模初步建立 ,信度和效度指标均达到了统计学要求 ;PDQ - 4 +对人格障碍诊断有较高的灵敏度和较低的特异度。
Objective: To develop norms of the Personality Diagnostic Questionnaire (PDQ-4+)and to examine its reliability and validity for assessing personality disorders in normal Chinese subjects and psychiatric patients. Methods: PDQ-4+ was administrated to the normal Chinese subjects ( n =628) and psychiatric patients ( n =367) recruited from 10 cities of China. Results: For the reliability of the scale, the test-retest cofficients ranged from .49 to .80(P<0.01); the split coefficients ranged from .50 to .93,and the alpha coefficients ranged from .56 to .78. For the validity the scale, the mean scores of 12 subscales of PDQ-4+ in patients group were significantly higher than those of the normal subjects. Factor analysis showed that PDQ-4+ possessed 3 dimensions which conform to the conceptual categorization of personality disorders. When PDQ-4+ was used as a diagnostic scale, it showed higher sensitivity than specificity. Conclusion: The reliability and validity of PDQ-4+ are satisfactory when applied to Chinese psychiatric patients and normal subjects.
