Cross-validating the Dot Counting Test Among an Adult ADHD Clinical Sample and Analyzing the Effect of ADHD Subtype and Comorbid Psychopathology.

This study cross-validated the dot counting test (DCT) as a performance validity test (PVT) in an adult attention-deficit/hyperactivity disorder (ADHD) clinical population and examined the effect of ADHD subtype and psychiatric comorbidity on accuracy for detecting invalidity. DCT performance was assessed among 210 consecutive adult ADHD referrals who underwent neuropsychological evaluation and were classified into valid ( = 175) or invalid ( = 35) groups based on seven independent criterion PVTs. The invalid group had significantly worse DCT performance than the valid group using both the standard and unrounded scoring procedure ().

Every second counts: A comparison of four dot counting test scoring procedures for detecting invalid neuropsychological test performance.

Although performance validity tests (PVTs) are an integral element of neuropsychological assessment, most PVTs have historically been restricted to the memory domain. The Dot Counting Test (DCT) is a nonmemory PVT shown to reliably identify invalid performance. Although several traditional and abbreviated scoring methods have been derived, no study to date has directly compared the available scoring approaches within a single sample.

Impaired or invalid? Limitations of assessing performance validity using the Boston Naming Test.

The Boston Naming Test (BNT) has been proposed as an embedded performance validity test (PVT), though replication is needed to provide further empirical support of its simultaneous use as a cognitive ability measure and embedded PVT. This cross-sectional study examined BNT performance in a mixed neuropsychiatric sample of 137 patients with/without cognitive impairment. Four independent criterion PVTs classified 109 (80%) as valid and 28 (20%) as invalid.

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).
