MMPI codes, different scores, and absolute elevations were combined in a multistage sequential decision rule for classifying profiles as N-type ("neurotic"), P-type ("psychotic"), and I-type ("indeterminate"). In cross-validation (N=988, 8 diverse clinical settings, half uncontaminated), the hit-rate among determinate cases ranged from 61% to 93% and totaled 76%. 30% of profiles are indeterminate. Methodological discussion and suggestions for further construct validation are presented.
