MMPI 中美 T 分对神经症与正常人区分效度的对照研究

Chinese—T score vs American—T score of MMPI:Discriminant validity for neurotic patients and normal subjects

采用明尼苏达多相个性调查表 (MMPI) 中国版399题,对102例神经症与100例正常人进行测查,比较中国 T 分(不加 K)与美国 T 分(加 K)两种标准下 MMPI 的量表区分度。结果发现,采用中国 T 分后神经症组呈现较为典型的1.2.3.7型剖面图,从整体上更能反映神经症性个性偏移的特征。同时,2量表 (D) 特异性有所提高。但另一方面又发现,2、7量表以及含有这两个量表的两点或两点以上编码模式敏感性下降。上述结果在一效度检验组中得到证实。

One hundred and two neurotic patients and 100 normal subjects completed 399—item Chinese versionof MMPI to compare the discriminant validity between Chinese—T(CT)score and American—T(AT)score of MMPI.Judged by Chinese—T score,the neurotic group presented a typical four—peak model of the scale 3(Hy),2(D),1(Hs),and 7(Pt),considered to be the characteristic model of personality deviation in neuroses.It is also found thatthough the specificity of scale D,by using cutoff point of 60 Chinese—T,increased significantly,the sensitivity of thescale Pt,D,and some relevant multi—point codes decreased significantly.Thus,it seemed that,in terms of discriminat-ing neurotic patients from normal subjects,the efficiency of CT by the two—points codes of Hs+Hy,Hy+D,or Hs+D is not different significantly from that of AT by any two combination of the scale D,Pt,Hs or Hy.Furthermore,if only by the scale D or Pt,or by the multi—points codes including either of them,the pseudo—negative rate of CTcriterion would go up more obviously.The authors argued that more consideration should be paid to cultural differencebetween China and American rather than to change T score criterion only.
