Recently, the Individual Work Performance Questionnaire (IWPQ) version 0.2 was developed using Rasch analysis. The goal of the current study was to improve targeting of the IWPQ scales by including additional items. The IWPQ 0.2 (original) and 0.3 (including additional items) were examined using Rasch analysis. Additional items that showed misfit or did not improve targeting were removed from the IWPQ 0.3, resulting in a final IWPQ 1.0. Subsequently, the scales showed good model fit and reliability, and were examined for key measurement requirements (e.g., category ordening, unidimensionality, and differential item functioning). Finally, calculation and interpretability of scores were addressed. Compared to its previous version, the final IWPQ 1.0 showed improved targeting for two out of three scales. As a result, it can more reliably measure workers at all levels of ability, discriminate between workers at a wider range on each scale, and detect changes in individual work performance.
最近，使用拉施分析开发了个人工作绩效问卷（IWPQ）0.2版。本研究的目的是通过纳入更多项目来改进IWPQ量表的针对性。使用拉施分析对IWPQ 0.2（原始版本）和0.3（包括更多项目）进行了检验。将显示不匹配或未改善针对性的额外项目从IWPQ 0.3中删除，最终形成了IWPQ 1.0。随后，这些量表显示出良好的模型拟合度和信度，并对关键测量要求（如类别排序、单维度性和项目功能差异）进行了检验。最后，解决了分数的计算和可解释性问题。与之前的版本相比，最终的IWPQ 1.0在三个量表中的两个上显示出针对性的改善。因此，它能够更可靠地测量各级能力的员工，在每个量表上更广泛地区分员工，并检测个人工作绩效的变化。
