Validity Indicator Profile (VIP)

The Validity Indicator Profile uses verbal and nonverbal subtests to measure response styles that are used by neuropsychologists, forensic psychologists, clinical psychologists, civil and criminal lawyers.  Test results help assess cognitive, neuropsychological, and other types of testing and whether they are valid representatives of peoples’ actual capacities.  The four response styles are Compliant, Inconsistent, Irrelevant, and Suppressed.

The format for the test includes a verbal subtest which has seventy-eight items and a nonverbal sub-test which has one hundred items.  The verbal part uses word-definition problems, whereas the other part uses nonverbal abstraction capacity.  Twenty minutes is required for the verbal part and thirty minutes for the nonverbal part.  Participants should be of ages eighteen to sixty-nine years.
