Abstract: 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.

Key words: MMPI Chinese norm, K scale, Differential ratio, Half sum of squares, Frequency analysis
