Examining independent and combined accuracy of embedded performance validity tests in the California Verbal Learning Test-II and Brief Visuospatial Memory Test-Revised for detecting invalid performance.

The California Verbal Learning Test-Second Edition (CVLT-II) Forced Choice Recognition (FC) and Brief Visuospatial Memory Test-Revised (BVMT-R) Recognition Discrimination Index (RD) are embedded performance validity tests (PVTs) assessing material-specific neuropsychological processes (i.e., verbal and visual memory, respectively). Prior research demonstrated the utility of these PVTs independently; however, no study has compared their diagnostic accuracy for identifying invalid performance relative to each other and in combination within a single sample. This cross-sectional study included an adult neuropsychiatric sample who underwent neuropsychological evaluation. Validity groups were determined via independent criterion PVT performance, and consisted of 103 participants with valid and 25 with invalid neurocognitive performance. FC and RD were not significantly correlated (
