MMPI/MMPI-2: comparisons of amnesic patients.
The amnesic population provides a unique opportunity to examine the reliability of clinical tests because amnesics do not consciously recollect initial testing sessions. In this study, amnesic subjects were studied to examine the reliability between the Minnesota Multiphasic Personality Inventory (MMPI) and the MMPI-2. Findings indicated that there were no statistical differences between versions of the MMPI and further revealed that many of the scales were significantly correlated. Amnesic patients produced elevated scores on subscales two (depression) and eight (schizophrenia), not unlike various other groups of neurologically impaired individuals. This indicates that MMPI and MMPI-2 scores in these patient populations may reflect the medical and psychosocial effects of brain damage rather than premorbid personality dysfunction. A close evaluation of amnesics' performance, in conjunction with the critical items they endorsed, offers insight into the personality traits of the amnesic patient population. The relative stability of performance across personality tests administered over several weeks is relevant to the formation and stability of the amnesic's concept of self.
