• The Borderline Personality Inventory (BPI) is a self-reported questionnaire for screening patients with borderline personality disorder. This study aims to construct and validate a shorter version of the original 53-item BPI suitable for use in Taiwan. A two-stage translation of the BPI was conducted and modified into colloquial language for use in Taiwan. It was tested against 3 groups of patients (borderline personality disorder, schizophrenia, neurotic disorders) and healthy subjects. After item analyses, a 20-item BPI was selected (BPI-T20), and its internal consistency was assessed. The validity was examined using relative operating characteristic (ROC) analysis. Altogether, 544 subjects successfully completed the study. The Cronbach's alpha coefficient was 0.92, while 3 factors were extracted from the questionnaire. The BPI-T20 had significant discriminatory power with satisfactory validity for borderline personality disorder, with an area under the ROCcurve of 0.93 at a cut-off point of 11/12. The sensitivity and specificity were 89.8% and 82.8% respectively, with a misclassification rate of 14.7%. The BPI-T20 appears to be reliable, effective and valid in screening borderline personality disorder. It could be applied in large-scale epidemiological community surveys.
