Preliminary screening stage of battery
During the preliminary screening stage in the development of the battery, items in the original pool that did not attain satisfactory inter-judge reliability were dropped. A 95% inter-rater agreement level was reported by the test constructors for the 282 items used in an early version of the battery developed after dropping those items. The manual having means and standard deviations for each item based on samples of control, neurologically impaired, and schizophrenic subjects. An alternate form of the battery is available. To the best of our knowledge, there have been no predictive validity studies. It is unclear whether or not there have been studies that address the issue of construct validity.
