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)。结论:加K矫正可提高临床量表对不同精神疾病的鉴别能力。

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 addedwere compared in schizophrenia( n=72)and obssesive-compulsive neurosis(n=31). Results: On the profile with K corrected, T scores onSc and Pt increased 2. 55T-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. WhenT-score is equal to or above 65, the casesof 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.
