摘　　要：目的：了解加Ｋ矫正对ＭＭＰＩ剖图的影响和临床意义。方法：比较精神分裂症组（ｎ＝７２）和强迫症组（ｎ＝３１）５个临床量表（Ｈｓ、Ｐｄ、Ｐｔ、Ｓｃ、Ｍａ）加Ｋ前后Ｔ分数的变化，量表间的相关性和疾病鉴别能力。结果：５个临床量表加Ｋ后，在精神分裂症组和强迫症组的ＭＭＰＩ剖图上，与这两类精神疾病诊断密切相关的量表Ｓｃ和Ｐｔ的Ｔ分数分别平均升高２．５５和３．９６个Ｔ分点；加Ｋ后的剖图，精神分裂症的两点编码由３６／６３改变为６８／８６，强迫症组由２３／３２改变为２７／７２。而且，加Ｋ前后，临床量表间的相关水平也发生变化，加Ｋ后使利用相应的编码解释的可能性增加。当Ｔ≥６５时，加Ｋ后两类精神疾病的人数分别增加１５．１％（Ｐ＜０．０５）和１６．１３％（Ｐ＜０．０１）。Objective:To understand the effect of adding K Correction on the profile of MMPI and its clinical significance. Methods: The changes of T scores on 5 clinical scales(Hs、Pd、Pt、Sc、Ma),the intercorrelations among 8 clinical scales before and after K added were compared in schizophrenia( n =72) and obssesive-compulsive neurosis( n =31). Results: On the profile with K corrected, T scores on Sc and Pt increased 2.55 T-point in schizophrenia group and 3.96 T-point in obssesive-compulsive neurosis group respectively. The two-point code changed from 36/63 to 68/86 in schizphrenia group, and from 23/32 to 27/72 in obssesive-compulsive neurosis group. In addition, the intercorrelations among scales are different, and this makes it more possible to use the code to interprete clinical diagnosis. When T-score is equal to or above 65, the cases of schizophrenia and obssesive-compulsive neurosis increased 15.1% ( P <0.05) and 16.13%( P <0.01) respectively.Conclusion:By K-correcting, the probability of using clinical scales to identity different mental diseases could be increased.
