How confusing an assessment might be? a case study in borderline personality disorder

Accurate diagnosis especially in personality disorders has been always challenging to select the most appropriate intervention method. However, the consistency between diagnostic methods based on patientchr('39')s self-report and methods based on the evaluation of clinicians is not satisfactory.

The present study aimed to investigate the consistency of diagnostic method based on clinicianchr('39')s evaluation and the method based on the patientchr('39')s self-report to select the most appropriate diagnostic method.

The present study was a clinical case study. The data were obtained from a 30-year-old male client using Structured Clinical Interview (SCID-II; First et al., 1994), Millon Clinical Multiaxial Inventory-III (MCMI-III; Millon, 1994), and unstructured interview assessment tools, and were explanatorily analyzed.

According to the results, the client was diagnosed with borderline personality disorder to the SCID-II, and despite the profile validity, there was found no elevation at the borderline scale of the MCMI-III.

No appropriate consistency was found between the method based on the evaluation of clinician and self-report-based method in this case study. In general, the results of the present study indicated that known and valid tests will not always lead to reliable results and the combination of several sources of evaluation is more appropriate and effective and result in more reliable results
