Assessing for Noncredible Presentations in ADHD Across the Lifespan

1.5 CE Credits

 

Julie A. Suhr, Ph.D.
Professor of Psychology and Director of Clinical Training
Ohio University






In this workshop, concerns about noncredible presentations of Attention Deficit Hyperactivity Disorder (ADHD) will be discussed. The workshop will include review of the existing research literature on noncredible presentations of ADHD in both children and adults. The base rates of noncredible presentation will be discussed. Evidence that assessment for noncredible presentation is currently lacking in most psychoeducational evaluations will also be presented. The workshop will include discussion of both noncredible self-report (including prior and current symptoms and impairment) and noncredible behavior on cognitive tests. Empirical evidence for the use of both Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs) in ADHD assessment across the lifespan will be reviewed, and some “best practices” based on this literature will be presented. There will also be attention given to development of new SVTs and PVTS for use in ADHD assessment, with discussion of research methodology relevant to both child and adult assessments.

After the session, participants will be able to:
1. Describe the need for assessment for noncredible presentations in both child and adult ADHD.
2. Explain the empirical support for SVT and PVT use in child and adult ADHD assessment.
3. Describe methods for development of new SVTs and PVTS for use on ADHD assessment across the lifespan.

Target Audience: Neuropsychologists and trainees

Review and Update on Adult Performance Validity Testing

1.5 CE Credits

Presented by:
Patrick Armistead-Jehle, Ph.D.
Chief, Concussion Clinic
Munson Army Health Center

This course will provide a review and update on performance validity testing (PVT) in adult neuropsychological evaluations.  Recent literature discussing the utility of validity testing in neuropsychological assessment, as well as reviews of stand-alone and embedded measures, will be discussed.  Special topics to be covered will include:  (1) feedback to patients and referring providers; and (2) use of PVTs in special populations. Emphasis will also be given to future directions in PVT research.

After the webinar, participants will be able to:

  1. Describe the influence of performance validity testing on interpretation of cognitive test results.
  2. Explain and utilize feedback strategies with patients and referring providers. 
  3. Discuss application of PVTs in patients with low IQ, dementia, and English as a second language.

Target Audience: Neuropsychologists, as well as psychologists involved in cognitive assessments.

Instructional Level: Intermediate

The Use of Positive and Negative Validity Findings in Clinical Versus Forensic Cases

1.5 CE Credits

 

Michael Chafetz, Ph.D., ABPP 
Algiers Neurobehavioral Resource, LLC







The central question of this workshop is whether negative validity test findings should be used in the aggregate along with positive test findings for the determination of a case of illness-deception (ID), as it was asserted by Frederick (2015) and Black, Necrason, and Omasta (2016). A comparison of the use of validity tests versus other kinds of medical and psychological tests is made, with findings suggesting that ID is fundamentally different from other constructs/diseases in evidence-based medicine, psychology, and neuropsychology because deception about illness involves a deliberate process that may involve coaching, research, and/or focusing the deception on one aspect of functioning (e.g., slowness). A case study is presented to consider how decisions about other medical and neuropsychological problems are enhanced by considering positive and negative findings, how likely findings are to be manipulated by the patient, and how well the assertion that both positive and negative validity test findings must be used together in the aggregate stands up to comparative scrutiny. The fundamental assumption that a negative test finding concerning ID represents good effort is flawed, as it simply represents a lack of evidence of ID which cannot, in turn, be construed as evidence of lack of deception. Commentary is provided on best practice in neuropsychology regarding use of validity tests.

After the session, participants will be able to:
1. Explain how positive and negative test results are used together to determine the probability of a given condition of interest in medicine and psychology.
2. Compare the changes in posterior probabilities from positive versus negative test findings for a condition of interest.
3. Describe how the case example supports using only positive test findings in a determination of illness-deception.

Dr. Michael Chafetz is a Board Certified clinical neuropsychologist in independent practice in New Orleans.  His research interests have focused on the validity of Social Security disability examinations, where he has sought to understand how validity testing operates in low functioning claimants.  This research led to an initiative to help the Social Security system produce more accurate assessments.  In these endeavors, he consulted with a United States Senator and the Office of the Inspector General to bring attention to this research in the Social Security system.  More recently, he consulted with the Swedish Social Security system to help bring about needed changes in assessment. His current research interests include the connection between factitious disorder and malingering and in the probability calculations you will see in this talk.
