The Big Five Inventory (BFI) is an instrument designed to assess the personality of individuals aged 18 and above. The original version consists of 44 items divided into five sub-scales representing each of the five personality factors: agreeableness, neuroticism, conscientiousness, openness, and extraversion. The main purpose of this study was to assess the factorial structure of the 44-item BFI and the reliability of two shorter versions with 20 and 10 items. The study also aimed to present normative data for interpreting scores from the short and ultrashort versions of the BFI for the Brazilian population. A total of 3565 individuals with a mean age of 33.3 years (SD = 13.0) from all Brazilian states participated in the study, with 44.2% from the State of Rio Grande do Sul. Participants completed a sociodemographic questionnaire and the BFI. Confirmatory factor analysis showed poor adaptation of the original 44-item model, but the short and ultrashort versions with 20 and 10 items respectively had good adaptation indexes and reliability, with Omega coefficients above 0.70. Normative data for the shorter versions were presented using mean, standard deviation, and percentiles (lower, medium, and higher). The study concluded that the short and ultrashort versions of the BFI have good reliability and can be used in surveys requiring a brief personality assessment.
大五人格量表（BFI）是一种用于评估 18 岁及以上个体人格的工具。其原始版本由 44 个项目组成，分为五个子量表，分别代表五个人格因素：宜人性、神经质、尽责性、开放性和外向性。本研究的主要目的是评估 44 项 BFI 的因子结构以及包含 20 项和 10 项题目的两个更简短版本的可靠性。本研究还旨在为巴西人群提供解释 BFI 短版和超短版得分的常模数据。共有来自巴西所有州的 3565 名年龄平均为 33.3 岁（SD=13.0）的个体参加了这项研究，其中 44.2%来自南里奥格兰德州。参与者完成了一份社会人口学问卷和 BFI。验证性因子分析表明，原始的 44 项模型适应性较差，但分别包含 20 项和 10 项题目的短版和超短版具有良好的适应指数和可靠性，Omega 系数均高于 0.70。使用平均值、标准差和百分位数（低、中、高）呈现了较短版本的常模数据。研究结论是，BFI 的短版和超短版具有良好的可靠性，可用于需要简短人格评估的调查。
