Doctor of Philosophy (Ph.D.)


A 405-item experimental Personality Adjective Check List (Strack, Note 2), which was developed in conjunction with an earlier research project, was refined into a 310-item form. This instrument is designed for use as a client rating inventory to assess the 11 personality disorders comprising Axis II of the Diagnostic and Statistical Manual of Mental Disorders III, DSM III, (American Psychiatric Association, 1980). Item selections were guided by personality theory (Millon, 1969, 1981). Empirical ratings and check list data were then collected from forty-six therapists located at 4 treatment centers, and were based on the responses of 204 clients. In addition, each client completed the Millon Clinical Multiaxial Inventory, MCMI, (Millon 1977, 1983). Scales for the 11 personality disorders were derived by a combination of rational and empirical procedures. The several steps taken in scale construction are presented in detail, as are preliminary MCMI validation statistics. Research projects aimed at further refining the scales and at establishing external validation are described.
