Using the IOP-29 in the Assessment of Disability and Impairment

November 10, 2021, 7:30 - 8:30 PM

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

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 November 10 on Using the IOP-29 in the Assessment of Disability and Impairment, and presented by Luciano Giromini, Donald J Viglione, & Laszlo A Erdodi


Evaluating the credibility of presented symptoms is a key component of psychological and neuropsychological assessments focused on possible disability or impairment. The Inventory of Problems-29 (IOP-29) is a useful addition to both routine clinical and high-stake forensic evaluations. The IOP-29 is a brief self-administered symptom validity test that is resistant to coaching and has superior excellent classification accuracy. The IOP-29 has been published It is available in several languages, allowing assessors to evaluate non-English speaking examinees without the involvement of translators.

This workshop will describe its development, research foundation, and how it can be integrated into existing assessment batteries to consolidate the empirical evidence used to determine the credibility of a given clinical presentation. The workshop concludes with case studies from Ontario to illustrate the benefits of using the IOP-29 in clinical and forensic settings.


NOTE: This session is open to psychologists, psychological associates and clinical psychology graduate students only.

_images/LErdodi.jpgLaszlo A Erdodi, PhD, is an Associate Professor of Psychology at the University of Windsor and a registered Clinical Neuropsychologist in the Province of Ontario, Canada. His main research interests revolve around performance validity tests (PVTs), emergent markers of neuropsychological status and the link between emotional and cognitive functioning. The common thread connecting these areas is the search for contextual variables associated with non-credible responding during neuropsychological assessment. The ultimate goal is to develop a better understanding of the complex relationship between the examinee’s personal history, current stressors and demands, psychiatric conditions, instrumentation artifacts and their effect on neurocognitive profiles. At the practical level, his research program is designed to identify clinically relevant and statistically robust predictors of invalid response patterns using embedded PVTs in isolation and aggregated into composite scores. Developing novel indices in well-established tests and exploring the advantages of a multivariate approach to performance validity assessment over single indicators is a recurrent theme in these investigations.
