Borderline personality disorder: an adaptation of the Taiwan short version of the screening inventory into Brazilian Portuguese

Abstract Objective The current study presents the translation and adaptation of the 20-item Taiwan version of the Borderline Personality Inventory (BPI) into Brazilian Portuguese (BPI-P). Methods After translation and back-translation, the Brazilian Portuguese version was administered to three samples: patients with borderline personality disorder, psychiatric patients with comorbid substance use disorder and volunteers with no reported mental disorders. Results Significant differences between groups for borderline scores (analysis of variance [ANOVA], F = 52.923, p = 0.01) were found but there were no significant correlations between scores for borderline personality disorder and alcohol or nicotine dependence. The BPI-P had satisfactory validity for borderline personality disorder, even when anxiety and depression were present, with an area under the receiver operating characteristic curve of 0.931 at a cutoff point of 14. Conclusion This study provides support for the potential utility of the BPI-P as a screening instrument for clinical practice in Portuguese speaking countries, including outpatients with alcohol and nicotine use disorders in early or sustained remission.摘要：研究目的 本研究旨在将20条目台湾版边缘型人格量表（Borderline Personality Inventory, BPI）翻译并调适为巴西葡萄牙语版本（BPI-P）。方法 经翻译与回译流程后，将该巴西葡萄牙语版本施测于三组样本：边缘型人格障碍患者、共病物质使用障碍的精神科患者，以及无精神障碍报告的志愿者。结果 三组受试者的边缘型人格量表得分存在显著组间差异，经方差分析（analysis of variance, ANOVA）验证，F=52.923，p=0.01；但边缘型人格障碍得分与酒精或尼古丁依赖程度未呈现显著相关性。BPI-P对边缘型人格障碍具有良好的效度，即便在合并焦虑与抑郁症状的情况下亦表现优异，其受试者工作特征曲线下面积在临界值14分时达0.931。结论 本研究证实BPI-P可作为葡萄牙语国家临床实践中的筛查工具，具备潜在应用价值，尤其适用于处于早期或持续戒断阶段的酒精与尼古丁使用障碍门诊患者。
