Abstract
ABSTRACTThe present study examines the Rey Auditory Verbal Learning Test (RAVLT) Embedded Performance Validity Indicator (EPVI) for detecting performance validity. This retrospective study analyzes the performance of four groups of 879 participants comprised of 464 clinically referred patients with suspected dementia, 91 forensic patients identified as not exhibiting adequate effort on other measures of response bias, 25 patients with well documented TBI, and a random sample of 198 adults collected in the Gulf State of Oman. The EPVI was also put to the test using normative data collected from the literature. Using sensitivity and specificity analyses, the results indicate moderate to high sensitivity yet low specificity. In conclusion, the study shows that the EPVI is a reasonably good indicator for inadequate effort on the RAVLT but those who fail this measure might not necessarily be exhibiting adequate effort. The limitations and benefits of utilizing the EPVI in clinical practice are discussed.
