This thesis explores the utility of established performance validity tests (PVTs) for assessing non-neurological aspects of test-taking behaviour in clinical populations. Part one is a systematic literature review examining the classification accuracy of a range of PVTs in dementia populations. Consideration is given to the impact of dementia severity and diagnosis on PVT specificity. Issues surrounding the use of cut-off scores on these measures are discussed. Part two is an empirical study exploring the base rate of failure on commonly-used PVTs in a sample of NHS acquired brain injury patients. The relationship between PVT failure and overall performance on cognitive testing is also assessed. Part three is a critical appraisal of the thesis which reflects on the broader clinical and conceptual challenges inherent in the field of performance validity testing as a whole.
