Improved Activity Evaluations: An Iterative Process Using the Rasch Model

Introduction: Traditional evaluation models, often linear and outcome-focused, are increasingly inadequate for the complexities of modern medical education, which demands more comprehensive and nuanced assessment approaches. Methods: A standardized continuing professional development activity evaluation instrument was developed and implemented. An iterative process was performed, using a repeat Rasch analysis, to improve reliability of the evaluation instrument. Category Probability Curves and Test Information Function were generated by the Rasch analysis to refine the construction of the…
