Composite descriptions associated with rare MMPI two-point code types in an adult urban psychiatric setting: codes...

MMPI files of 1,016 psychiatric patients were searched for protocols with two-point codes that involved scale 0. Thirty-eight such protocols were found, which accounted for 3.7% of the sample. Salient characteristics of the cases were noted, and composite descriptions were developed for each of the code types. An additional 14 new outpatient cases from our clinic were located over the next 2 years. Base rates from the original sample, as well as descriptive statistics and composite descriptions from the extended sample, are provided for each of the eight code types.
