The Inventory of Problems – 29 (IOP-29; Viglione, Giromini & Landis, 2017) is a brief and effective symptom validity test (SVT). It is designed to assist practitioners evaluating the credibility of various symptom presentations, including those related to (1) depression/anxiety, (2) psychosis/schizophrenia, (3) post-traumatic reactions, and (4) neuropsychological/intellectual dysfunction. Comprised of 29 items, it can be administered via classic, paper-and-pencil format, or online, using a tablet or a PC. By analyzing the responses to each of these 29 items, a logistic regression-derived formula generates the False Disorder Probability Score (FDS), a probability value reflecting the likelihood of drawing that specific IOP-29 from a group of experimental feigners versus a group of bona fide patients. Based on emerging research attesting to the utility of combining symptom validity with performance validity measures, a new “add-on” feature of the IOP-29 has recently been developed. Named "IOP-M," its format is that of a brief, forced-choice, performance validity test (PVT). This half-day workshop will first review available research informing on the complex relationship between symptom and performance validity assessment. Then, it will describe the research foundation for using the IOP-29 and IOP-M in malingering evaluations and it will present guidelines for their use in applied practice. Together, these two brief tests, each taking five to ten minutes, provide the most efficient symptom and performance measure for the busy practitioner. No prior experience with the IOP instruments is required.s.
Goals and Objectives:
1. Describe the research findings observed when investigating the complex relationship between symptom and performance validity assessment
2. Understand the research foundation for using the IOP-29 and IOP-M to evaluate the credibility of various mental illness complaints
3. Compare the efficacy of the IOP-29 and IOP-M versus other available tools such as SIMS, TOMM, PAI and MMPI
4. Administer and score the IOP-29 and IOP-M
5. Interpret and integrate the results of IOP-29 and IOP-M
No prior experience with the IOP instruments is required, and all psychologists and graduate students at all levels of training may attend this introductory workshop.
