Conclusions: Our data shows there were greater failure rates on both memory PVIs for persons with TBI. That said, considering that PVT false positive rates hover around 15% in clinical samples and many test designers attempt to create PVTs with false positive rates of 10% or less, the BVMT-R PVI cut off proposed by Denning appears to be suitable for use with clients with TBI.

Objective:

The California Verbal Learning Test-II (CVLT-II) and Brief Visuospatial Memory Test-Revised (BVMT-R) are two common neuropsychological measures that assess memory functioning. Research has shown that persons with traumatic brain injury (TBI) demonstrate significant memory deficits. Embedded performance validity indicators (PVI) have been increasingly used in neuropsychological testing to measure performance credibility across domains. This study was designed to examine proposed embedded PVI cut-off scores for the classification accuracy of the CVLT-II total learning score (Shura et al., 2015) and BVMT-R recognition hits (Denning, 2012) in individuals with TBI.

Participants and Methods:

The sample consisted of 75 individuals with moderate-to-severe TBI and 57 healthy comparison participants. TBI participants were tested 6 months or more post-injury. Participants were excluded if they failed two free-standing performance validity tests (PVT), the Dot Counting Test and Rey-Fifteen Item Test plus Recognition. Chi-square analyses of the CVLT-II Total Learning Trials and BVMT-R Recognition Hits were used to evaluate PVI failure rates between groups.

Results:

Chi-square analysis indicated a significant failure rate difference between groups (TBI group: 57%; HC: 25%) on the embedded CVLT-II PVI, X²=14.18, p < .001, Ф = .33. However, there was no significant failure rate difference between groups (TBI group: 5%; HC: 0%) on the embedded BVMT-R PVI, X²=3.14, p = .077, Ф = .15.

Conclusions:

Our data shows there were greater failure rates on both memory PVIs for persons with TBI. That said, considering that PVT false positive rates hover around 15% in clinical samples and many test designers attempt to create PVTs with false positive rates of 10% or less, the BVMT-R PVI cut off proposed by Denning appears to be suitable for use with clients with TBI.
