<p> The purpose of this study was to determine the reliability and validity of the Dot Counting Test as a measure of feigned cognitive performance. Archival neuropsychological test data from a “real world” sample of 147 credible and 328 non-credible patients were compared. The Dot Counting Test E-score cutoff of ≥ 17 continued to show excellent specificity (93%). However, sensitivity dropped from approximately 74% documented in 2002 to 51% in the current sample. When the cutoff was lowered to ≥ 15, adequate specificity was maintained (90%) and sensitivity rose to (61%). However, a third of credible patients with borderline IQ failed the test using the Dot Counting Test E-cutoff score, indicating cautious use of the test with individuals who likely have borderline intelligence.</p><p>
