An improved MMPI short form: The MMPI-168-E

Abstract

K‐corrected MMPI‐168 scales using short and long form K scales (N = 2439). The latter increased the correlation between abbreviated and standard scales in most instances. Because using the entire K scale involves the addition of only 18 items to the MMPI‐168 while it generally improves the statistical validity of several scales in addition to K, this was proposed as a cost‐effective means of improving the MMPI‐168.
