Abstract

This study examined the validity of MMPI scores and MMPI-based cognitive complaints as indicators of memory and concentrational disturbances in 70 closed-head-trauma patients. The relation of scores on the MMPI Depression (D), Schizophrenia (Sc), Mental Dullness (D4), Lack of Ego Mastery, Cognitive (Sc2A), and Organic Symptoms (Org) scales to actual memory performance on the WA1S-R Digit Span and Wechsler Memory Scale (Russell's revision) subtests was explored. The results suggest an absence of any relation between actual memory performance on any of these subtests and MMPI scores or a Cognitive Complaint Index consisting of 8 MMPI items. Findings are discussed in light of the questionable validity of memory complaints in other samples, as well as possible limitations in the ecological validity of current tests of memory.
