Borderline personality disorder (BPD) is one of the most studied personality disorders and is associated with significant outcomes such as suicide. Although BPD is represented in as a categorical diagnosis, it may be better characterized dimensionally, such as from the perspective of the five-factor model of general personality (FFM). The Five-Factor Borderline Inventory (FFBI) assesses BPD from the perspective of maladaptive variants of FFM traits. Previous research suggests that informant-reports may increase the validity of personality disorder assessment, providing additional information that may supplement self-report. Therefore, the current study developed an informant measure of the FFBI, Informant Five-Factor Borderline Inventory (IFFBI) and examined its convergent and discriminant validity compared with the self-report FFBI, FFM, and traditional measure of BPD. Overall, the IFFBI demonstrated good convergent validity and moderate discriminant validity with the FFBI, FFM, and other traditional measures of BPD.
边缘型人格障碍（BPD）是研究最多的人格障碍之一，与自杀等严重后果相关。尽管BPD在分类诊断中有所体现，但从维度上进行描述可能会更好，比如从一般人格五因素模型（FFM）的角度。五因素边缘型人格量表（FFBI）从FFM特质的适应不良变体角度评估BPD。先前的研究表明，他人报告可能会提高人格障碍评估的效度，提供可补充自我报告的额外信息。因此，本研究开发了一种FFBI的他人评定量表，即他人五因素边缘型人格量表（IFFBI），并与自我报告的FFBI、FFM以及BPD的传统测量方法相比，检验了其聚合效度和区分效度。总体而言，IFFBI与FFBI、FFM以及BPD的其他传统测量方法相比，显示出良好的聚合效度和中等的区分效度
