Preliminary investigation of the Denver Attention Test (DAT) in a mixed clinical sample

Abstract

In this pilot study, the clinical utility of a new computerized performance validity test (PVT) called the Denver Attention Test (DAT) was evaluated in a known-groups experimental design. Subjects consisted of 130 adults with mixed neurological conditions evaluated in an outpatient setting. Using the Word Memory Test (WMT) to categorize subjects into valid and invalid groups, the DAT was found to have adequate discrimination. Classification statistics for the DAT demonstrated low to moderate sensitivity and excellent specificity relative to the WMT. ROC analyses demonstrated AUCs of at least .78 for select DAT subtests. Overall, data from this pilot study suggest that the DAT has potential to serve as a useful PVT. Future research directions are discussed.
