The importance of quickly assessing personality traits in many studies prompted the development of brief scales such as the Ten-Item Personality Inventory (TIPI), a measure of five personality traits (extraversion, agreeableness, conscientiousness, emotional stability, and openness). In the current study, we present the Portuguese version of TIPI and examine its psychometric properties, based on a sample of 333 Portuguese adults aged 18 to 65 years. The results revealed reliability coefficients similar to the original version (α = 0.39–0.72), very good 4-week test–retest reliability (n = 81, rs > 0.71), expected factorial structure, high convergent validity with the Big-Five Inventory (rs > 0.60), and correlations with self-esteem, affect, and aggressiveness similar to those found with standard measures of personality traits. Overall, our findings suggest that the Portuguese TIPI is a reliable and valid alternative to longer measures: it offers a promising tool for research contexts in which the available time for personality assessment is highly limited.

诸多研究中快速评估人格特质的需求，推动了十项人格量表（Ten-Item Personality Inventory, TIPI）等简版人格量表的开发。该量表可测评五大人格特质：外向性、宜人性、尽责性、情绪稳定性与开放性。本研究以333名年龄介于18至65岁的葡萄牙成年人为样本，推出TIPI的葡萄牙语版本，并对其心理测量学属性展开检验。研究结果显示，该量表的信度系数与原版相近（α=0.39~0.72），4周重测信度表现极佳（有效样本量n=81，相关系数rs>0.71），因子结构符合预期，与大五人格量表（Big-Five Inventory）的会聚效度较高（rs>0.60），且其与自尊、情感及攻击性的相关模式，与标准人格特质测评工具所得结果一致。综上，本研究结果表明，葡萄牙语版TIPI可作为长版人格测评工具的可靠且有效替代方案：对于人格测评时间极为有限的研究场景，该量表是极具应用前景的测评工具。
