Abstract
Objective: This study investigated whether indices within the Brief Visuospatial Memory Test – Revised (BVMT-R) could function as embedded performance validity measures in an outpatient clinical sample.Method: A sample of 138 neuropsychological outpatients was utilized; approximately 45% had a known or suspected external incentive. Patients were determined to be valid performers if they passed all criterion performance validity tests (PVTs) and determined to be invalid performers if they failed two or more PVTs. BVMT-R indices met criteria for optimal embedded PVTs if they were not significantly correlated with genuine cognitive dysfunction and if they adequately differentiated the validly from invalidly performing patient groups. Classification accuracy statistics for the indices were then calculated. Supplementary analyses were also calculated for a separate dementia sample.Results: Recognition Hits and Recognition Discrimination were identified as two optimal embedded PVTs for patients without dementia. Recognition Hits showed a sensitivity rate of 41% and a specificity rate of 95%. Recognition Discrimination showed a sensitivity rate of 54% and a specificity rate of 93%.Conclusion: Embedded BVMT-R PVTs are discussed in relation to previous research findings, which were obtained from veteran samples. Recognition Hits and Recognition Discrimination are now validated in a non-veteran clinical sample.
