Age, stage, and the MMPI: changes in response patterns over an 85-year age span

Statistically significant and clinically relevant age-related changes in MMPI response patterns have long been known to clinicians. Graphic representations of mean scores that cover an 85-year age span, separately by sex, for each of the 13 basic MMPI validity and clinical scales support the use of adolescent norms and indicate that clinicians should give greater acknowledgement to age-related MMPI changes in adults and their interpretation, particularly among geriatric patients.
