In recent years there has been an increased interest in the development of neuropsychological tests that can diagnose accurately brain damage. The most successful of these test are represented in the Halstead-Reitan Neuropsychological Battery, which has been shown to be 90% or more effective in the diagnosis of brain damage. However, this battery is not available to many psychologists or clients because of its length, cost, and the considerable background required to use it properly. The present study tested 121 Ss (30 normal, 91 brain-damaged) to develop an abbreviated version of the battery that is relatively brief (1 hour) and inexpensive, but accurate. It was found by discriminant analysis that the abbreviated battery is capable of diagnosing brain damage equally as well as the full battery 93% of the time. The limitations and advantages of the abbreviated battery are discussed
