DSM Rating Form (DSMRF). The DSMRF is a one-page measure that assists the clinician in providing dimensional ratings for each of the 10 DSM-IV personality disorders in a manner comparable to the FFMRF. All 10 DSM-IV personality disorders are listed along with a brief one-sentence description. The clinician rates the extent to which the individual is characterized by each of the disorders on a 1-5 Likert scale where 1 = absent, 2 = subthreshold, 3 = threshold, 4 = above threshold, and 5 = prototypic. After rating each disorder, the clinicians were also asked to provide a final DSM-IV diagnosis, for which they could select: A) One or more of the above diagnoses, B) personality disorder not otherwise specified (PDNOS), or C) no personality disorder diagnosis.
Clinical Utility Questionnaire. After completing the DSMRF and the FFMRF, the clinicians were asked to rate both the DSM and the FFM descriptions on each aspect of clinical utility. This questionnaire was designed to assess components of clinical utility outlined by First et al. (2004). The six questions that were addressed were: 1) How easy do you feel it was to apply the system to this individual, 2) how useful do you feel the system would be for communicating information about this individual with other mental health professionals, 3) how useful do you feel this system would be for communicating information about the individual to him or herself, 4) how useful is this system for comprehensively describing all the important personality problems the individual has, 5) how useful would this system be for helping you to formulate an effective intervention for this individual, and 6) how useful was this system for describing the individual’s global personality. These ratings were provided on a 1-5 Likert scale, where 1 = not at all useful, 2 = slightly useful, 3 = moderately useful, 4 = very useful, and 5 = extremely useful.
