The Rey-Osterrieth Complex Figure Task (ROCFT) has been a standard in neuropsychological assessment for six decades. Many researchers have contributed administration procedures, additional scoring systems and normative data to improve its utility. Despite the abundance of research, the original 36-point scoring system still reigns among clinicians despite documented problems with ceiling and floor effects and poor discrimination between levels of impairment. This study is an attempt to provide a new method based upon item response theory that will allow clinicians to better describe the impairment levels of their patients. Through estimation of item characteristic curves, underlying traits can be estimated.Creation InformationDecember 2008.ContextThisis part of the collection entitled:andwas provided byto,a digital repository hosted by the.It has been viewed 8291 times, with 23 in the last month.More information about this dissertation can be viewed below.

An item response theory analysis of the Rey Osterrieth Complex Figure Task. Doctor of Philosophy (Health Pyschology and Behavioral Medicine), December 2008, 85 pp., 37 tables, 7 illustrations, references, 47 titles. The Rey-Osterrieth Complex Figure Task (ROCFT) has been a standard in neuropsychological assessment for six decades. Since the original drawing, there have been a number of elaborations of the test, the most commonly known of these is the Rey-Osterrieth Complex figure and the Taylor alternate version. Each version of the complex figure test is administered using the same general format. The individual.

Through estimation of item characteristic curves, underlying traits can be estimated while taking into account varying levels of difficulty and discrimination within the set of individual items. The ultimate goal of the current research is identification of a subset of ROCFT items that can be examined in addition to total scores to provide an extra level of information for clinicians, particularly when they are faced with a need to discriminate severely and mildly impaired patients.

About This ProductBY PHILIP FASTENAU, PHDThe ECFT retains the strengths and overcomes the limitations of the Rey-Osterrieth Complex Figure Test (CFT), a standard measure of perceptual organization and visual memory in brain-injured individuals.Like the CFT, the ECFT asks the patient to copy a complex geometric figure. It then assesses the patient’s immediate and delayed recall of the figure. Unlike the CFT, however, the ECFT adds Recognition and Matching trials to the design-copying task. This allows you to distinguish perceptual abilities from constructional skills and to determine the relative contributions of encoding and retrieval processes. In addition, a Short Form ensures that the test can be used with people who have limited use of their preferred hand. These enhancements give the test greater diagnostic sensitivity.The ECFT is useful not only in evaluating the effects of head injury, stroke, seizure, various medical conditions, and exposure to neurotoxins, but also in differentiating depression from dementia; distinguishing dementia-related memory deficits from normal, age-related memory lapses; and identifying aspects of memory functioning relevant to rehabilitation.
