Abstract: This paper used factor analysis to assess the structure validity of aChinese version of the Minnesota Multiphasic Personality Inventory(MMPI)which was administered to 1095 subjects: 633 normal subjects and 462 psy-chiatric patients. Separate factor analysis were performed on six groups ofsubjects: four groups of normal subjects divided according to their sexand educational level and two groups of psychiatric patients divided acc-ording to their sex. Principal component analysis(with varimax rotation)of the 13 standa-rdized scale scores that sequentially extracted three, four, five and six fa-ctors generated almost the same factor structure in all six groups. Thesix-factor solution generated the following factors: psychoticism, neuroti-cism, introversion-extroversion, overcontrol, antisocial characteristic andmasculinity-femininity. The main MMPI factors found in China are consi-stent with those found in America and other countries, The result has alsobeen used to form six factor-scales of the MMPI to assist MMPI inte-rpretation.
