Neuropsychologists are being increasingly called upon to demonstrate the value of their services. This edited book introduces clinical neuropsychologists to the concepts and challenges involved in conducting cost outcome research. It provides examples of how such research can be conducted within clinical neuropsychology and therefore is a "e;beginning"e; step in what must become an interdisciplinary effort. The text suggests that more than cost effectiveness studies should be considered when demonstrating the clinical utility of neuropsychological services. The concept of "e;objective"e; and "e;subjective"e; markers of value is emphasized, particularly as it relates to measuring the impact of a neuropsychological examination. Chapters review the economic burdens associated with different neurological conditions commonly seen by neuropsychologists. They also provide examples of how clinical neuropsychological services to different patient populations may reduce "e;costs"e; and increase "e;benefits"e; and suggest directions for beginning cost outcome research. Furthermore, the book summarizes the utility of various neuropsychological services that may be helpful to readers concerned with healthcare economies. The book is intended as a resource for clinical neuropsychologists who wish to explain to healthcare providers the value of their work. It is the first book of the National Academy of Neuropsychology book series entitled: Neuropsychology: Scientific Bases and Clinical Application.
