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.

Introduction: This study cross-validates and expands upon previous research by examining the optimal number of PVT failures necessary to determine invalid performance when 10 PVTs are administered during a neuropsychological evaluation. 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 looked at why certain embedded performance validity indicators (EVIs) lead to higher false-positive rates (FPRs) in ADHD evaluations among adults, focusing on 15 EVIs from six cognitive tests.
- The research involved 517 adults with ADHD and found that while some EVIs had FPRs over 10% when used alone, combining them reduced the overall FPR to 8.1%.
- The study concluded that the choice of tests and the number of EVIs used are crucial for reducing FPRs in ADHD assessments, emphasizing the need for more refined approaches to test validity.
Article Synopsis
- This study explored whether high cut-scores on the Barkley Adult ADHD Rating Scale-Fourth Edition (BAARS-IV) can indicate when adults might be overreporting ADHD symptoms during evaluations.
- Researchers analyzed data from 162 adults, dividing them into valid and invalid groups based on their symptom validity tests, and found that certain cut-scores effectively distinguished between these groups.
- The study suggests using specific cut-scores from the Current Total and Current Sluggish Cognitive Tempo scales together to better identify symptom overreporting, recommending that scores above these thresholds should lead to further examination of the patient's claims.
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.
