Response consistency among high F scale scorers on the MMPI

Classified male psychiatric inpatients (N = 200) with high (T greater than 90) scores on the MMPI F scale as either consistent or inconsistent responders using the Test-Retest (TR) Index. As predicted, consistent MMPI responders appeared to exaggerate pathology, while inconsistent responders' profiles were indicative of random responding on the MMPI. Results supported use of the TR Index in enhancing interpretation of MMPI profiles with very high F scale scores.
