Minimizing evaluation time while maintaining accuracy: Cross-validation of the Test of Memory Malingering (TOMM) Trial 1 and first 10-item errors as briefer performance validity tests.

Current standards of practice in neuropsychology advocate for including validity tests (PVTs). Abbreviating PVTs, such as the Test of Memory Malingering (TOMM), may help reduce overall evaluation time while maintaining diagnostic accuracy. TOMM Trial 1 performance (T1), as well as the number of errors within the first 10 items of Trial 1 (TOMMe10), have shown initial promise as abbreviated PVTs but require additional external cross-validation.

Evaluation of the classification accuracy of multiple performance validity tests in a mixed clinical sample.

The Test of Memory Malingering (TOMM) and Word Memory Test (WMT) are among the most well-known performance validity tests (PVTs) and regarded as measures. Due to the many factors that impact PVT selection, it is imperative that clinicians make informed clinical decisions with respect to additional or alternative PVTs that demonstrate similar classification accuracy as these well-validated measures. The present archival study evaluated the agreement/classification accuracy of a large battery consisting of multiple other freestanding/embedded PVTs in a mixed clinical sample of 126 veterans.

Comparison of models of premorbid IQ estimation using the TOPF, OPIE-3, and Barona equation, with corrections for the Flynn effect.

Objective: Premorbid estimates of intellectual functioning are a key to assessment. This study aimed to compare 3 common measures and assess their accuracy: the Test of Premorbid Functioning (TOPF), Oklahoma Premorbid Intelligence Estimate (OPIE-3), and what is commonly referred to as the . We also sought to provide appropriate adjustment considering the Flynn effect.

The Word Memory Test genuine memory impairment profile discriminates genuine memory impairment from invalid performance in a mixed clinical sample with cognitive impairment.

: The Word Memory Test (WMT) is a memory-based performance validity test (PVT) with adjusted interpretive criteria (Genuine Memory Impairment Profile; GMIP) proposed for those with cognitive impairment (CI). The GMIP has been criticized for poor discriminability; thus, this study sought to validate the GMIP in a mixed clinical sample. Analyses aimed to demonstrate enhanced detection of invalid neuropsychological test performance while minimizing false positives in a sample including patients with mild CI.
