The Relationship Between Subjective Cognitive Complaints, Invalid Symptom Reporting, and Neurocognitive Test Performance Validity Among Adults Being Evaluated for ADHD.

Objective: Subjective cognitive complaints are common among patients presenting for evaluation of attention-deficit/hyperactivity disorder (ADHD). Despite these complaints, research overwhelmingly suggests that reported cognitive deficits do not align with objective neurocognitive performance. This study explored the relationship between subjective cognitive complaints, objective neuropsychological functioning, and performance and symptom validity testing in adult patients referred for evaluation due to concern about ADHD.

Additionally, the study assessed the degree of skewness of individual PVTs and PVT intercorrelations for the overall sample and by validity group.
Method: Participants were 283 adult neuropsychology outpatients evaluated at an academic medical center.
Article Synopsis
- - This study explored how the severity of processing speed impairment affects performance on the Rey 15-Item Test (RFIT) and its recognition variant, revealing that those with intact processing speed scored better than those with reduced or impaired speeds.
- - Data from 285 neuropsychological assessments were analyzed, using various standardized tests to measure processing speed and other cognitive functions, with results showing significant predictive power from both verbal/visual memory and processing speed.
- - While the RFIT tests showed good classification accuracy for individuals with intact processing speed, their effectiveness dropped significantly for those with impaired speeds, indicating that the RFIT may not be suitable for evaluating individuals with greater processing speed deficits.
Article Synopsis
- * The study included 129 adult outpatients and found that combining MIL and MCT-AI improved the detection of invalid performance, increasing sensitivity from 10-31% to 70% while keeping specificity above 90%.
- * Results indicate that failing either test is linked to lower cognitive scores, and failing both leads to significantly lower scores, supporting the idea that using multiple PVTs in assessments is beneficial.
Objective: The Making Change Test (MCT) is a brief, digitized freestanding performance validity test (PVT) designed for tele-neuropsychology (TeleNP). The objective of this study was to report the initial validation of the MCT in a mixed neuropsychiatric sample referred for neuropsychological evaluation using a known-groups design.
Method: The sample consisted of 136 adult outpatients who underwent a neuropsychological evaluation.
