Exploring the Evidence to Interpret Differential Item Functioning via Response Process Data.

ABSTRACT: Evaluating differential item functioning (DIF) in assessments plays an important role in achieving measurement fairness across different subgroups, such as gender and native language. However, relying solely on the item response scores among traditional DIF techniques poses challenges for researchers and practitioners in interpreting DIF. Recently, response process data, which carry valuable information about examinees' response behaviors, offer an opportunity to further interpret DIF items by examining differences in response processes. This study aims to investigate the potential of response process data features in improving the interpretability of DIF items, with a focus on gender DIF using data from the Programme for International Assessment of Adult Competencies (PIAAC) 2012 computer
