An MMPI sign to separate organic from functional psychiatric patients

Abstract
Evaluated the utilities of all 90 possible unweighted additive/subtractive two scale MMPI combinations as indices to separate brain-damaged from functional patient groups in a Veterans Administration psychiatric hospital. One index, Hs – PT, showed more promise than any of the other 89. HS – PT mean scores were significantly higher among organics than among alcoholics, neurotics, affective psychoses, character disorders, process schizophrenics or reactive schizophrenics. Interpretative information on the HS – PT index was presented.
