This article examines the development and validation of the Validity Indicator Profile (VIP).
The Validity Indicator Profile (VIP) is a two-alternative forced choice procedure intended to identify when the results of cognitive and neuropsychological testing may be invalid because of malingering or other problematic response styles. The test consists of 100 problems that assess nonverbal abstraction capacity and 78 word-definition problems. The VIP attempts to establish whether an individual’s performance in an assessment battery should be considered representative of his or her true overall capacities (valid or invalid). Performances classified as valid are “compliant” and reflect a high effort to respond correctly. Performances classified as invalid are “careless” (low effort to respond correctly), “irrelevant” (low effort to respond incorrectly) or “malingering” (high effort to respond incorrectly). The VIP development sample included 944 nonclinical participants and 104 adults undergoing neuropsychological evaluation. The cross-validation sample consisted of 152 nonclinical participants, 61 brain-injured adults, 49 individuals considered at-risk for malingering and 100 randomly generated VIP protocols.
