Based on Item Response Theory, and more specifically the Rasch model, the financial knowledge domain included in the OECD/INFE adult financial literacy assessment conducted in 2015 was evaluated. This was done in order to determine whether the measurement instrument, in its existing design, could be classified as an International Large-scale assessment (ILSA), suitable for within countries and for comparison across countries. The development cycle of the OECD/INFE assessment was briefly presented to portray the conditions necessary to ensure that successful measurement would lead to action. Based on the first phase of the analysis, the suitability of the data for the Rasch model was established and the applicability of the instrument to country-specific analysis was confirmed. However, the differential item function (DIF) exploration determined that the assumption that item difficulties are homogeneous across the various countries does not hold, therefore confirming the utility of this study. The results highlighted the greater risk associated with the traditional ranking of results rather than with sophisticated analyses, as traditional approaches could result in misdiagnosis of problem areas on instruments which might not be comparable across countries. Based on the results, it does not seem that the OECD/INFE adult financial knowledge assessment adhere to the requirements of being classified an ILSA.

使用Rasch模型对OECD / INFE金融知识评估的比较分析

基于项目响应理论，更具体而言，基于Rasch模型，对2015年进行的OECD / INFE成人金融素养评估中所包括的金融知识领域进行了评估。这样做是为了确定测量工具在其现有设计中是否可以归类为国际大型评估（ILSA），适用于国家内部和国家间比较。简要介绍了OECD / INFE评估的开发周期，以描绘确保成功进行测量可以采取行动所需的条件。基于分析的第一阶段，确定了Rasch模型数据的适用性，并确认了该仪器对特定国家/地区分析的适用性。然而，差分项目函数（DIF）探索确定了在各个国家/地区中项目难度相同的假设不成立，因此证实了这项研究的实用性。结果强调，与传统的结果排名相比，与复杂的分析相比，存在更大的风险，因为传统的方法可能会导致对工具上存在问题的区域进行误诊，这在各国之间可能无法比拟。根据结果​​，经合组织/ INFE成人财务知识评估似乎不符合被分类为ILSA的要求。结果强调，与传统的结果排名相比，与复杂的分析相比，存在更大的风险，因为传统的方法可能会导致对工具上存在问题的区域进行误诊，这在各国之间可能无法比拟。根据结果​​，经合组织/ INFE成人财务知识评估似乎不符合被分类为ILSA的要求。结果强调，与传统的结果排名相比，与复杂的分析相比，存在更大的风险，因为传统的方法可能会导致对工具上问题区域的误诊，这在各国之间可能是无法比拟的。根据结果​​，经合组织/ INFE成人财务知识评估似乎不符合被分类为ILSA的要求。
