Screening for psychopathology in groups of black and white prison inmates by means of the MMPI

Of 225 male offenders who were administered both the MMPI and a structured diagnostic interview, the Psychiatric Diagnostic Interview (PDI), 51 (25 blacks, 26 whites) earned highly elevated MMPI profiles (at least one clinical scale greater than or equal to T score of 90) and 46 (26 blacks, 20 whites) achieved profiles that were essentially within normal limits (all clinical scales less than T score of 70). It was noted that the concordance between the MMPI and the total number of PDI syndromes reported by inmates was significantly greater in the white group (classification accuracy = 96%) relative to the black group (classification accuracy = 71%). However, both the black and white hit rates were found to significantly improved upon chance.
