Underreporting of difficulties on the MCMI-III is suggested by low scores (raw score less than 34) on Disclosure (X) and Debasement (Z) and a high score (BR over 75) on Desirability (Y; an “arrow” profile on the Modifying Indices). However, it is sometimes difficult to differentiate persons who are faking good (underreporting) from those who actually have the positive qualities of being cooperative, self-confident, and conscientious. The client’s history is often the best tool for making this distinction.
