Fundamentals of Performance Validity Tests in Neuropsychological and Psychological Forensic and Related Disability Assessment

February 28, 2025, 2:00 - 5:15 PM

During this webinar, Dr. Young and Dr. Laszlo will review core concepts related to Forensic Disability and Related Assessment (FDRA), based on the significant amount of research conducted in the field; this will include critical issues of debate among various researchers. Dr. Gerald Young and Dr. Laszlo Erdodi will also address empirical and methodological issues for determining the merit of symptom and performance validity measures.  The webinar will also point out counterarguments to Dr. Leonhard who delivered a presentation on the topic of validity testing to CAPDA on November 22, 2024. Of note, the counterarguments to Leonhard’s criticisms are divided into the following three categories:   1. Conceptual Foundations; 2. Psychometrics (“Testing the tests”), and 3. Practical/FDRA Implications.

The workshop concludes with a summary of legitimate concerns about performance validity measures (e.g. limitations in predictive power) and how to address these limitations in high-stake FDRAs. Dr. Young and Dr. Erdodi will identify the reasons that performance and symptom validity measures provide valuable information about a patient’s clinical condition.  As such, there are strong arguments for validity measures to be implemented in psychological and neuropsychological assessments. This webinar will significantly assist practitioners who are required to defend the use of validity measures in arbitration and court.

 

LEARNING OBJECTIVES

As a result of this webinar, participants will be able to:    

  • Address the value and validity of using performance validity measures in forensic neuropsychological assessment
  • Respond to criticisms of the value and validity of performance validity measures in forensic neuropsychological assessment
  • Defend the use of performance validity measures in forensic neuropsychological assessment by referencing key position statements, reviews, and commentaries from published journal articles.
  • Argue persuasively for the use of performance validity measures in neuropsychological assessment by referencing critical empirical research
  • Prepare effective psychological and neuropsychological reports and testimony for court based on a list of 100 fundamental principles (critical ones will be reviewed; the others posted) underlying the value of utilizing performance validity measures in psychological and neuropsychological forensic and related disability assessments.

ABOUT THE PRESENTERS

Dr. Laszlo A. Erdodi, Ph.D., C. Psych.

Dr. Laszlo Erdodi is a clinical neuropsychologist and Associate Professor of Psychology at the University of Windsor. He is a licensed Psychologist in Ontario. He earned his Ph.D. in Clinical Psychology from Eastern Michigan University, with a pre-doctoral internship at the London Health Sciences Centre in neuropsychology. He completed his post-doctoral fellowship in Neuropsychology at the Geisel School of Medicine at Dartmouth.

His research interests revolve around performance validity tests (PVTs) within neuropsychological assessment, improving psychometric tools for assessing a variety of neuropsychiatric conditions, the effect of psychogenic interference and limited English proficiency on performance on cognitive testing. He has developed a multivariate procedure for aggregating embedded validity indicators that captures both the number and extent of PVT failures, providing a more nuanced measure of performance validity.

 

Dr. Gerald Young Ph.D., C.Psych., C-CAT (MB), CMLE (ON)

Dr. Gerald Young is a Full Professor in Psychology at Glendon College, York University, Toronto, Canada. He is a Fellow of the Association for Psychological Science (APS) and the American Psychological Association (APA).

Young is Editor-in-Chief of the journal Psychological Injury and Law, which he founded, and his work in that area has led to invited speaker addresses at scientific conferences. His most recent books include: Revising the APA Ethics Code (Springer, 2017) and Causality and neo-stages in development: Toward unifying psychology (Springer, 2022). His next book is co-edited and on Handbook of Psychological Injury and Law (Springer Nature, in preparation). He has appeared as an expert witness for a case involving the Supreme Court of Canada.
