Dr. Victor has authored or co-authored several peer-reviewed publications in the field of neuropsychology. Her research has focused on identifying the effects of normal aging on the brain, the influence of culture and language on neuropsychological test performance, and the development and validation of performance and symptom validity indicators...

This authoritative volume is the first book specifically devoted to symptom validity assessment with individuals with a known or suspected history of mild traumatic brain injury (MTBI). It brings together leading experts in MTBI, symptom validity assessment, and malingering to provide a thorough and practical guide to the challenging task of assessing the validity of patient presentations after an MTBI. The book describes techniques that can drastically alter case conceptualization, treatment, and equitable allocation of resources. In addition to covering the most important symptom validity assessment methods, this timely volume provides guidance to clinicians on professional and research issues, and information on symptom validity testing in varied populations.

Comprehensive and user friendly, this book synthesizes the growing literature on symptom feigning in cognitive testing and translates it into evidence-based recommendations for clinical and forensic practice. A wide range of cognitive effort assessment techniques and strategies are critically reviewed, including both dedicated measures and the use of embedded indicators in standard clinical tests. The book describes approaches to distinguishing between credible and noncredible performance in specific clinical populations: persons presenting with head injury, chronic pain and fatigue, attention-deficit/hyperactivity disorder and learning disability, mental retardation, seizures, and exposure to environmental toxins. Special topics include the potentially confounding effects of psychiatric disorder and ethnocultural factors on effort testing, and cognitive assessment in the criminal forensic setting.

This book provides neuropsychologists with comprehensive information and specific practice recommendations for the assessment of patients with somatoform conditions. The first four chapters discuss the genesis of somatoform and other functional somatic symptom disorders, and the next seven chapters address somatoform conditions in the context of nonepileptic seizures, multiple chemical sensitivity and other claimed toxic exposures, pseudotremor and other nonphysiologic movement disorders, postconcussion syndrome, chronic pain/fibromyalgia/complex regional pain syndrome, attention deficit disorder, and auto-immune disease. Chapters are also included that address the use of the MMPI-2-RF in differentiating somatoform disorder and malingering; medically unexplained symptoms in non-English-speaking individuals; workplace factors in somatization; and testimony involving somatoform conditions. The book is targeted for practicing neuropsychologists, clinical psychologists including those specializing in behavioral medicine, and students in training.

The go-to resource for clinical and forensic practice has now been significantly revised with 85% new material, reflecting the tremendous growth of the field. Leading authorities synthesize the state of the science on symptom feigning in cognitive testing and present evidence-based recommendations for distinguishing between credible and noncredible performance. A wide range of performance validity tests (PVTs) and symptom validity tests (SVTs) are critically reviewed and guidelines provided for applying them across differing cognitive domains and medical, neurological, and psychiatric conditions. The book also covers validity testing in forensic settings and with particular populations, such as ethnic and linguistic minority group members.
