MMPI Scoring & Validity Scales

After taking the MMPI-2 an interpretive report is constructed. The scores are converted to normalized “T scores” on a scale ranging from 30 to 120. The scores are analyzed according to a person and not a group of people. The MMPI is usually administered with other psychological tests so that the test can confirm or deny the results that are suggested by the MMPI. The MMPI includes six specific scales that serve as indicators of test validity:

L Scale Presence of virtues in greater abundance than the norm
K Scale Indicates if problems have been minimized
TRIN True Response Inconsistency, where opposite answers are both marked as true
VRIN Variable Response Inconsistency, indicating random answers
F Scale Atypical Answers
