Session Abstract: Recent research has demonstrated that the IOP-29 is a perfect complement to performance validity tests like the TOMM in the multi-method assessment of symptom validity.  As such, we developed an incidental recall task to be used immediately after administering the IOP-29 to evaluate the credibility of presented memory problems.  In this paper, we present the development of this new IOP-29 add-on application, which we named the IOP-M, and report on some initial research testing its validity and utility.  More specifically, we describe the leading principles we attended to when refining the IOP-M throughout its six versions, as well as the empirical findings we obtained in this pilot research.  Additionally, we also summarize findings from six international studies investigating the classification accuracy and incremental validity of the IOP-M with participants from Italy, France, Slovenia, Brazil, England and Australia. Taken together, these preliminary reports suggest that using the IOP-M in combination with the IOP-29 yields some incremental validity, not only when inspecting feigned cognitive problems (e.g., mTBI symptoms) but also when focusing on feigned depression, PTSD or schizophrenia.

Dr. Erdodi is an Associate Professor in Psychology and a licensed clinical neuropsychologist. He completed his PhD in Clinical Psychology at Eastern Michigan University, and pre-doctoral internship at the London Health Sciences Center specializing in clinical neuropsychology. After one year in private practice focusing on forensic neuropsychology, he completed a two-year post-doctoral fellowship in clinical neuropsychology at the Geisel School of Medicine at Dartmouth. He joined the Department of Psychology in 2014 as a member of the Clinical Neuropsychology Track. His long-standing research interests revolve around psychometrics, performance validity testing in neuropsychological assessment, the relationship between cognitive and emotional functioning, and limited English proficiency as a confounding variable in neurocognitive testing. He is also interested in the broader issue of instrumentation in psychological assessment: the interaction among administration time, order effects, testing paradigms, the influence of contextual variables (geographic region, incentive status, trauma history, current psychosocial functioning) on the clinical interpretation of test data. The psychometric, diagnostic and clinical challenges inherent in the assessment and treatment of patients with medically unexplained symptoms or with complex psychological trauma history, along with cross-cultural neuropsychology are his emerging areas of interest.
