Disorders of adult personality and behaviour (F6). Results from the ICD-10 field trial of the Diagnostic Criteria for Research in German-speaking countries.

Results of the ICD-10 Diagnostic Criteria for Research (DCR) field trial in German-speaking countries revealed a high level of interrater reliability (kappa = 0.79) for disorders of adult personality and behaviour (section F6) with marked differences between specific diagnoses: borderline personality = 0.76, transsexualism = 0.98, factitious disorder = 0.33. Compared with the results of the field trial concerning the Clinical Guidelines for section F6 of ICD-10, the application of the more precise and restrictive DRC led to an improvement of general kappa values of 0.15.
