Development of main effect DIF and interactive DIF detection method in cognitive diagnosis assessments: A recursive partitioning-based perspective

Key Points

• The study aims to address limitations in existing DIF detection methods used in cognitive assessments, particularly for interactive DIF.
• Developed a method called ISRPM using recursive partitioning techniques.
• Conducted simulation studies to compare ISRPM's performance with traditional DIF detection methods.
• Performed empirical research to assess ISRPM's consistency and effectiveness in real assessment scenarios.
• ISRPM performs comparably with traditional methods in main effect DIF detection.
• ISRPM outperforms traditional methods in detecting interactive DIF.
• Empirical research shows high consistency between ISRPM and traditional DIF outcomes.
