A brief clinical neuropsychologic screening battery: statistical classification trials.

Classified independently 150 neuropsychiatric referrals into Definite (DBD), Suspected (SBD) or No Brain Damage (NBD) groups on the basis of nonneuropsychological evaluative data. Each S was examined with a brief, 2-hour neuropsychologic screening battery, and the test data were analyzed by a stepwise linear discriminant function program. Statistical classifications were compared with criteria for NBD vs. SBD + DBD and for SBD vs. DBD groupings. Hit rates ranged from 95% for the former to 81.7% for the latter, with the low false positives and negatives. Hit and miss rates were not as strong in a validation step, but exceeded chance levels.
