This study attempted to cross‐validate an MMPI Key for the separation of brain‐damaged and schizophrenic inpatients. MMPI profiles generated by 20 males with a variety of documented brain dysfunctions were compared to those of 20 heterogenous male schizophrenics. The groups were matched on the variables of age and education. The procedure provided 82.5% correct classification, which included 85% correct schizophrenic identification and 80% correct brain‐damage identification. The Key was recommended for use as a rough screening device or as a supplement to appropriate neuropsychological procedures.
