ABSTRACT
The Minnesota Multiphasic Personality Inventory, the MMPI (Hathaway & McKinley, 1940, 1983), and its recent offspring, the MMPI—2 (Butcher, Dahlstrom, Graham, Teilegen, & Kaemmer, 1989), are the most widely used psycho pathology measures in the world (Butcher & Rouse, 1996; Lubin, Larsen, Matarazzo, & Seever, 1985). With item pools of unparalleled richness for characterizing psychopathology and many normal-range personality traits, these inventories are the questionnaires of choice in numerous clinical and research contexts (Ben-Porath & Waller, 1992). For these reasons psychologists are keenly interested in the underlying factor structure of the MMPI item pool. Although many have tried to uncover this structure (e.g., Archer & Klinefelter, 1991; Comrey, 1957a, 1957b, 1957c, 1958a, 1958b, 1958c, 1958d; Costa, Zonderman, & Williams, 1985; Johnson, Null, Butcher, & Johnson, 1984; Reddon, Marceau, & Jackson, 1982) a replicable factor structure for the MMPI has yet to be found.
