Abstract:
A three-factor model of personality pathology was investigated in a clinical sample of 183 female patients in an outpatient eating disorders treatment program. Cluster analysis of MCMI-II personality scales (Millon, 1987) yielded three distinct personality profiles, which were consistent with previous studies. First, 16.9% of the sample comprised a High Functioning cluster, which manifested no clinical elevations on the MCMI-II and had significantly lower scores on the Eating Disorder Inventory (EDI; Garner; 1991) scales than the other two clusters. Second, 49.1% of the sample comprised an Undercontrolled/Dysregulated cluster. Finally, the remaining 34% of the sample comprised an Overcontrolled/Avoidant cluster. This final cluster had significantly higher EDI Ineffectiveness scale scores than the Undercontrolled/Dysregulated cluster group. Cluster membership was not associated with eating disorder subtype, suggesting that there is considerable variance in personality pathology within eating disorder diagnostic categories.
