The MMPI-2 The Essentials To K-correct, or not to K-correct? Research doesn’t support the use of the K-correction on the MMPI-2 Little correlation differences between K and non-K corrected and other clinical variables Several have found the K-corrected to be worse at prediction of other clinical variables Recommendation: Don’t use them Cannot Say (?) The total number of omitted items (or items answered both T and F) Can be due to indecisiveness, to avoid admitting faults, or carelessness/confusion “Official” rule is 30+ omitted items = invalid Graham recommends 10 omits = use caution If many items are omitted, examine which scales they come from (automatic on computer scoring) 1 Variable Response Inconsistency (VRIN) VRIN was developed for MMPI-2 and indicates tendency to respond inconsistently Does so by using 67 pairs of items that ask similar questions, then comparing the answers to those questions Use to help understand high F scale scores High F and high VRIN support random responding High F and normal VRIN suggest either severely disturbed or “faking bad” True Response Inconsistency (TRIN) Used to identify all true or all false responding patterns Higher scores indicate indiscriminate true responses, lower indicate indiscriminate false responding Raw scores of 13+ (80+ T-scores in the direction of true) indicate all true responding Raw scores of 5 or less (80+ T-scores in the direction of false) indicate all false responding Infrequency (F) Developed to detect deviant / atypical ways of responding to test items Used in conjunction with VRIN, TRIN, and Fp to determine whether someone is truly disturbed,
