| Abstract: | A seeded duster analysis procedure was applied to the Minnesota Multiphasic Personality Inventory (MMPI) profiles of 102 male and 63 female back-pain patients. For both men and women, the resulting subgroups were found to correspond closely to similar subgroups obtained in several previous investigations. New data on the psychometric properties of the MMPI Alexithymia scales (Kleiger & Kinsman, 1980) are presented. Significant differences in alexithymia among empirically derived MMPI subgroups were found in the male sample only. |
