Measurement of Eating Pathology Using the Minnesota Multiphasic Personality Inventory-3 (MMPI-3).

Eating disorders are prevalent among college student populations. Although previous iterations of the instrument did not include specific measurement of eating pathology, the Minnesota multiphasic personality inventory-3 (MMPI-3) now includes a specific scale (i.e., Eating Concerns [EAT]) to assess problematic eating behaviors. The current study examined the MMPI-3 assessment of eating pathology among 249 undergraduate women. A pattern emerged where symptoms of internalizing psychopathology on the MMPI-3 were generally associated with symptoms of eating disorder. However, the newly included EAT scale demonstrated the strongest associations with most areas of eating dysfunction. Further, hierarchical regression analyses suggested that the EAT scale added substantial incremental predictive utility (up to 23%) over other MMPI-3 scales combined in assessing eating pathology. Classification accuracy statistics yielded high sensitivity and specificity coefficients when predicting eating disorder risk at an EAT scale score cutoff of 75 T or higher. These findings support the use of the MMPI-3 in assessing eating pathology in college women, although its performance with men and with women not of college age remains to be studied.
