MMPI中国常模中量表8及量表9K校正系数的探讨

DO WE NEED TO MAKE K CORRECTIONS ONTO SCORES OF SCALE 8 AND SCALE 9 OF THE MMPI CHINESE NORMS?

本文针对MMPI中国常模中各临床量表一般不作K分校正的建议作了实证研究。其分析了912名被试的K、Sc及Ma量表数据资料,其中有345名精神分裂症患者,111名躁狂症患者以及456名正常被试。利用半和方区分比率法和频数分析法进行分析的结果表明,为了使MMPI在辅助诊断心理失常者时达到较好的效果,①量表8原始分数需加1K校正分数;②量表9原始分数以0.2K分数进行校正较不作校正为好。由此本研究建议,在应用MMPI时应采用加K分的中国常模。

This study is to provide an empirical criteria for Chinese MMPI users tomake decision on the problem of whether or not the MMPI Chinese normswith K correction should be used in their clinical practice. All data of K, Scand Ma scales were from 912 subjects, among whom 345 were schizoids, 111maniacs and 456 normal persons. The traditional methods of'half sum of squ-ares' and the freqnency analysis were used in this study. The results showed:a) Sc scale (Scale 8) raw score should be added with 1.0 K scale score; b)it is better to have 0.2K scale score added into Ma scale (Scale 9) than notin terms of the largest differential ratio value and the best hitting rate achie-ved. So this study suggests that we should use the K corrected MMPI Chinesenorms.
