An Investigation of the Eating Concerns Scale of the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) in a Postoperative Bariatric Surgery Sample.

Eating pathology is common pre-operatively and continues to be prevalent following bariatric surgery. A new version of the Minnesota Multiphasic Personality Inventory (MMPI), the MMPI-3, contains a new scale called Eating Concerns (EAT) that aims to assess problematic eating behaviors. The current investigation seeks to establish preliminary convergent validity of the MMPI-3 EAT scale in a postoperative bariatric surgery sample. Thirty-eight consecutive participants took the MMPI-3 and the Eating Disorder Examination-Questionnaire (EDE-Q). Higher MMPI-3 EAT scale scores were meaningfully associated with %Weight Regain (r = .37) and scale scores on the EDE-Q [Eating Concerns (r = .67), Weight Concerns (r = .39), Shape Concerns (r = .54), and the EDE total score (r = .59)]. Initial examination of the EAT Specific Problem Scale of the MMPI-3 yields good clinical utility in assessing eating pathology in a postoperative bariatric surgery sample.
