The Proactive Personality Scale (PPS) is used widely to measure proactive personality. Previous research has evaluated the psychometric properties of the 6-item PPS (hereafter called PPS-6) using classical test theory. There is a need to provide further validity evidence for the PPS-6 using modern test theory. This study evaluated the psychometric properties of the PPS-6 using Rasch analysis. A total of 429 participants completed the PPS-6. Rasch rating scale model (RSM) was used to analyse the data. RSM showed that the PPS-6 fitted the Rasch model well. RSM demonstrated that the PPS-6 functioned as a unidimensional measure with good internal consistency reliability. Items on the PPS-6 did not show any noticeable differential item functioning across gender. RSM showed that the response rating scale of the PPS-6 is suitable. Results suggest that the PPS-6 is a reliable measure for the assessment of proactive personality.
《主动性人格量表》（PPS）被广泛用于测量主动性人格。先前的研究已经使用经典测试理论评估了 6 项 PPS（以下简称 PPS-6）的心理测量特性。需要使用现代测试理论为 PPS-6 提供进一步的有效性证据。本研究使用 RASCH 分析评估了 PPS-6 的心理测量特性。共有 429 名参与者完成了 PPS-6。Rasch 评分量表模型（RSM）用于分析数据。RSM 表明，PPS-6 很好地符合了 Rasch 模型。RSM 表明，PPS-6 作为一个具有良好内部一致性可靠性的单维度量标准。PPS-6 上的项目在性别上没有表现出任何明显的差异项目功能。RSM 表明，PPS-6 的反应评分量表是合适的。结果表明，PPS-6 是评估主动性人格的可靠工具。
