Multivariate Models of Performance Validity Assessment

June 15, 2022, 7:30 - 9:00 PM

The CAPDA Board of Directors is pleased to offer a series of Zoom sessions titled "Truth Through Discourse", which offers open discussion on various topics of interest to psychologists, psychological associates and clinical psychology graduate students.

Normally scheduled from 7:30 - 8:30 pm each month, these discussions are offered free for CAPDA members and $5 for non-members for each session.

Our next session is scheduled for Wednesday June 15 from 7:30 -9:00 pm (1 hour lecture and 30 minutes for Q&A).

Dr. Laszlo Erdodi will discuss Multivariate Models of Performance Validity Assessment: logic, evidence and clinical interpretation.


Laszlo Erdodi is an Associate Professor in Psychology at the University of Windsor and a registered clinical neuropsychologist in Ontario. He completed his PhD in Clinical Psychology at Eastern Michigan University, a pre-doctoral internship at the London Health Sciences Center specializing in clinical neuropsychology and a two-year post-doctoral fellowship in clinical neuropsychology at the Geisel School of Medicine at Dartmouth in Lebanon NH (USA). His long-standing research interests revolve around psychometrics, performance validity testing in cognitive assessment, and cross-cultural neuropsychology. He developed a novel method for aggregating multiple individual PVTs into a composite measure of performance validity that takes into account both the number and extent of PVT failures, while acknowledging the indeterminate range as a legitimate third outcome of performance validity assessment. The empirical support for the EI model has been rapidly accumulating in recent years.


This workshop will feature a specialized section on interpretation of the MMPI-3 with compensation seeking/disability claimants.

It will be presented by the MMPI-3's lead author, Dr. Yossi Ben Porath.
