Validation of the Spanish version of the Borderline Personality Disorder Checklist (BPD Checklist) in a sample of BPD patients: Study of psychometric properties

© 2017 Asociación Universitaria de Zaragoza para el Progreso de la Psiquiatría y la Salud Mental Background and objectives: Borderline Personality Disorder (BPD) is one of the most complex personality disorders (PD). The Borderline Personality Disorder Checklist (BPD Checklist) is an instrument specifically designed to assess the burden of BPD symptoms according to DSM-IV/5 criteria in the past month. Methods: Our goal was to adapt and validate the BPD Checklist in Spanish and to study its psychometric properties, i.e. reliability and validity. We administered it in a sample of BPD patients (n = 342) and in a sample of patients with other PD diagnoses (n = 190). Results: The results obtained indicated that the psychometric properties of the Spanish version of the BPD Checklist are similar to those of the original version of the instrument. The internal consistency indices were generally good to excellent. The total score and the subscales of the BPD Checklist discriminated between diagnostic samples. As expected, the subscales were associated with the scores on the SCID-II and self-rating measures. Conclusions: Our results are consistent with the original version of BPD Checklist. In general, it is an adequate instrument for clinical screening and to assess the subjective burden of BPD experienced by the patient in the past month.
