A Structural Analysis of the Impact of MMPI-2 on MMPI-1

Minnesota Multiphasic Personality Inventory-1 (MMPI-1) items modified for Minnesota Multiphasic Personality Inventory-2 (MMPI-2) are presented in pairs to illustrate modifications. MMPI-1 items deleted from MMPI-2 are presented, grouped by categories. Frequencies of items remaining in MMPI-2 for the following special scales are presented: Harris and Lingoes subscales of the clinical scales (Harris & Lingoes, 1955/1968); Wiggins Content scales (Wiggins, 1966); Tryon, Stein, and Chu (TSC) cluster scales (Stein, 1968; Tryon, 1966); Indiana Rational scales (Levitt, 1989); and selected other special scales. Frequencies of MMPI-1 items in the MMPI-2 validity and content scales are also presented, k is concluded that most of the special scales developed for MMPI-1 remain relatively intact in MMPI-2.
