Abstract

The 50-item International Personality Item Pool version of the Big Five Markers (IPIP-BFM) is an open-source and widely used measure of the big five personality traits. A short version of this measure (IPIP-BFM-25) has been developed using the classical test theory approach. No study was performed to examine the psychometric properties of a longer and shorter version of IPIP-BFM Indonesia using modern test theory. This study aimed to evaluate the psychometric properties of the Indonesian version of IPIP-BFM as well as IPIP-BFM-25 using Rasch analysis. The analysis was conducted in order to test their dimensionality, rating scale functioning, item properties, person responses, targeting, reliability, and item bias on 1003 Indonesian samples. The findings showed that both IPIP-BFM and IPIP-BFM-25 Indonesia have some adequate psychometric properties, especially regarding category function, item properties, reliability, and item bias. However, the emotional stability and intellect scales did not meet the assumption of unidimensionality, and all items on the scales were too easy to endorse by participants. In general, longer measures outperformed shorter measures in terms of person separation and reliability. Further testing and refinement must be conducted.

国际个性项目库五大标记量表的Rasch分析：时间越长越好？

五大标记的50项国际个性项目库版本（IPIP-BFM）是一种开源的、广泛使用的五大个性特征测量方法。使用经典测试理论方法开发了该度量的简短版本（IPIP-BFM-25）。没有使用现代测试理论对印度尼西亚IPIP-BFM的长短版本的心理测量特性进行研究。本研究旨在使用Rasch分析评估印尼版IPIP-BFM和IPIP-BFM-25的心理测量特性。该分析旨在对1003个印尼样本的维度、评分量表功能、项目属性、个人反应、目标定位、可靠性和项目偏见进行测试。研究结果表明，IPIP-BFM和IPIP-BFM-25 Indonesia都具有足够的心理测量特性，尤其是在类别功能、项目特性、可靠性和项目偏倚方面。然而，情绪稳定性和智力量表不符合单一维度的假设，并且量表上的所有项目都太容易被参与者认可。总的来说，在人员分离和可靠性方面，较长的衡量标准优于较短的衡量标准。必须进行进一步的测试和改进。
