MMPI-2 Validity Indices

compliance --> omission (? or cannot says, cutoff 30) --> response pattern --> VRIN & TRIN (cutoff 80) --> L (cutoff 65) --> K & S (cutoff 65) --> F & F(B) (60-80 a large number of mental health problems; cutoff 90; 110 malingering); Elevations of more than T = 60 on the F(p) mean that this individual has endorsed considerably more mental health symptoms than most psychiatric patients do.

* ? or Cannot Says - cut off 30 (raw score)

* L (lying; faking good) - cut off 65 (T score)

* F (faking bad) - cut off 90 (T score) exaggerated symptom presentation

* K (test defensiveness) - cut off 70 (T score)
In practice, K does not really improve empirical discrimination over non-K corrected scores (Archer, Fontaine, & McCrae, 1998; Sines, Baucom, & Gruba, 1979).

* Yea-saying and nay-saying: If 20% or less of the items are endorsed in the true or false direction, the protocol is likely to be invalid.

* VRIN (Variable Response Inconsistency scale) - random responding

* TRIN (True Response Inconsistency scale) - TRIN-T > 80 respond inconsistently in the true direction; TRIN-F

* S (superlative self-presentation scale) - defensiveness; high S responders are viewed by their spouses as emotionally well-controlled and generally free of pathological behavior features.
