A validity scale on the Minnesota Multiphasic Personality Inventory (MMPI)-2, consisting of 67 pairs of items (49 unique pairs) that either have similar or opposite content. Depending on the content of the item pair, inconsistent responding can take the form of the same (e.g., both “true” and “false”) or different responses. Very high or very low scores are indicative of inconsistent responding. Greene (1991) suggested cutoff scores of seven or below, and 16 or higher, to indicate inconsistent responding (p. 69). Pinsoneault (2007) found the VRIN scale to be the most sensitive to random responding of the available MMPI-2 validity scales. The clinical neuropsychologist integrates information from MMPI inconsistency measures together with other neuropsychological data and symptom validity scores to determine whether the inconsistency reflects random responding and/or carelessness versus a cognitive impairment issue (e.g., reading comprehension and attention)....
