[Validation of a Spanish version of the Diagnostic Interview for Bordelines-Revised (DIB-R)].
BACKGROUND
Borderline Personality Disorder (BPD) is the most studied Axis II disorders. However, there are no Spanish versions of specific interviews. The Diagnostic Interview for Borderlines-Revised (DIB-R) is a semistructured interview used to determine the diagnosis and severity of BPD patients. The aim of this study was to validate the DIB-R for use in a Spanish-speaking sample.


METHODS
The psychometric characteristics of the DIB-R Spanish version were assessed in a sample of 156 patients with the possible diagnosis of borderline personality disorder. There were 29 men and 127 women with a mean age of 27.6 years (SD: 6.5; range: 18-45). The Spanish adaptation of the Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) was used as gold standard.


RESULTS
The DIB-R showed good total internal consistency (Cronbach's alpha: 0.89) and high inter-rater reliability (within-class correlation: 0.94). Using logistic regression analyses the best cut-off was judged to be 6 or more, obtaining high sensitivity (0.81), specificity (0.94) and moderate convergent validity of the diagnosis with the SCID-II (kappa: 0.59).


CONCLUSIONS
The Spanish version of the DIB-R showed psychometric characteristics similar to those in the original interview and may be useful to determine BPD presence and severity.
