Purpose -The paper aims to give an introduction into symptom validity assessment (SVA) to non-experts in the field of neuropsychology. Design/methodology/approach -The analysis is based on the knowledge of the progress in this field which can be conceived as one of the most prolific developments in forensic neuropsychological assessment. Findings -By its very nature, clinical neuropsychology is a data-driven discipline, both on the level of single-case assessment and in research. In forensic contexts where secondary gain is immanent, uncooperativeness and malingering may threaten the integrity of data, so much so that no valid conclusions may be drawn from the data. Originality/value -In the last 20 years, clinical and forensic neuropsychologists have been more prominent in the development of methods to detect response distortions and to identify malingering than any other profession. In forensic contexts, neuropsychological evaluations without SVA must be considered incomplete. Clinically and forensically working psychologists should strive to have a thorough knowledge of symptom validity assessment.
Clinical and forensic neuropsychologyClinical neuropsychology as a scientifically based discipline deals with the brain-behaviour relationship. Thus, it may be more qualified than any other discipline to answer questions about consequences of brain damage on human behaviour. In clinical and rehabilitative contexts, neuropsychological assessment, counselling, and therapy has a long tradition of determining cognitive, emotional, and social consequences of impaired brain functioning which may arise as sequelae of traumatic brain injury (TBI), cerebrovascular accidents, brain tumor, inflammatory diseases of the central nervous system, alcoholism, etc.For the assessment of cognitive functioning, neuropsychological tests have been developed to measure such domains as memory, attention, visuospatial abilities, language, and executive functions. Tests continue to be one of the major tools used by neuropsychologists. For a number of domains, test results have been shown to be a good predictor of everyday functioning. Standardized psychological tests are the basis of what makes neuropsychology a data-driven discipline.In the context of personal injury litigation, workplace accidents, and social security legislation, neuropsychologists have increasingly been involved as expert witnesses in cases where possible behavioural consequences of brain injury are disputed.
