![]() Both simulator groups were asked to feign concussion symptoms, but the coached group received a test-taking strategy and a description of concussion symptoms. Four-hundred volunteers were randomly assigned to one of three groups: uncoached simulators' group (n = 118), coached simulators' group (n = 136), or control group (n = 146). We hypothesized that the N-Tri would have comparable sensitivity and specificity to traditional tests but would have improved accuracy for detecting coached simulators. The study describes the validation of a computerized adaptation of the novel Tri-Choice Naming and Response Bias Measure (N-Tri) developed to detect untruthful responding while being less susceptible to coaching than existing measures. Collectively, our findings suggest that these tasks may not be vulnerable to simulated cognitive impairment, and that the tasks measure largely non-overlapping aspects of decision making. Few significant correlations emerged among tasks across studies and the pattern of relationships between tasks did not differ on the basis of simulator or PVT failure status. Across studies, participants simulating impairment were not distinguishable from controls on any of the behavioral tasks. They then completed a battery of tests including embedded and standalone performance validity tests (PVTs) and three behavioral decision making tasks. Across two studies (Study 1: n = 166, Study 2: n = 130), undergraduate student participants were asked to try their best or to simulate a specific diagnosis (Attention-Deficit/Hyperactivity Disorder Study 1), decision making impairment (Study 2), or general cognitive impairment (Study 2). The present study examined relationships among decision making tasks and whether simulated impairment moderates the relationships among them. In addition, it is unclear whether these tasks are sensitive to invalid performance or even simulated impairment. However, correlations among these tasks are low, indicating each may assess a distinct component of decision making. RDS for the NAB appears to be an adequate indicator of performance validity however, considering the very small number of participants who were invalid on the WCT (n = 15), as well as the utilization of only one stand-alone PVT to classify validity status, these findings are preliminary and in need of replication.īehavioral decision making tasks are common in research settings, with only the Iowa Gambling Task available for clinical assessments. The optimal cutoff for RDS was identified (<8). The area under the curve (AUC) value for RDS was 0.702 however, AUC values for all other digit span indices were unacceptably low. Analyses showed that RDS demonstrated acceptable classification accuracy between those who passed the WCT and those who did not. Receiver operating characteristic (ROC) curves, t-tests, and sensitivity and specificity analyses were conducted. Participants were 92 adults (ages 19-68) who completed NAB Digits Forward and Digits Backward, and the Word Choice Test (WCT). Retrospective archival chart review was conducted at an outpatient neuropsychology clinic. It does not store any personal data.The purpose of this study was to evaluate multiple embedded performance validity indicators within the Digits Forward and Digits Backward subtests of the Neuropsychological Assessment Battery (NAB), including Reliable Digit Span (RDS), as no published papers have examined embedded digit span validity indicators within these subtests of the NAB.
