Abstract

Criteria of DSM-III were used as source material for items in a psychopathology inventory series. The inventories provided DSM-III diagnoses by reproducing the DSM-III decision process through diagnostic keys. The personality disorders inventory (ADI) was chosen as initial research instrument. Forty-seven voluntary clients from two sites served as clinical subjects and 29 non-clinical volunteers, given special directions to avoid diagnosis, served as subjects for validity scales. Four clinical psychologists matched DSM-III criteria with ADI items in measurement of content validity. Results showed that the ADI was not a useful psychometric instrument in its present form. The ADI gave too many false positive diagnoses, and also gave too many false negative diagnoses to serve usefully as a screening instrument. There were significant differences for sex, site, sex within site A and site within females. A framework of attribute quality and attribute quantity was suggested by data juxtaposition, and resultant instrument revisions were derived.
