Diagnostic Radiology Residency Assessment Tools: A Scoping Review

Abstract

Purpose: The multifaceted nature of learning in diagnostic radiology residency requires a variety of assessment methods. However, the scope and quality of assessment tools has not been formally examined. A scoping review was performed to identify assessment tools available for radiology resident training and to evaluate the validity of these tools. Methods: A literature search was conducted through multiple databases and on-line resources. Inclusion criteria were defined as any tool used in assessment of radiology resident competence. Data regarding residents, evaluators and specifics of each tool was extracted. Each tool was subjected through a validation process with a customized rating scale using the 5 categories of validity: content, response process, internal structure, relations to other variables, and consequences. Results: The initial search returned 447 articles; 35 were included. The most evaluated competency being overall knowledge (31%), most common published journal was Academic Radiology (24%) ; evaluations were most commonly set in the United States (57%). In terms of validation, we found low adherence to modern integrated validity, with 34% of studies including a definition of validity. When specifically examining the 5 domains of validation evidence presented, most were either absent or of low rigor (70%). Only one study presented a modern definition of validation (3%, 1/35). Conclusion: We identified 35 evaluation tools covering a variety of competency areas. However, few of these tools have been validated. Development of new validated assessment tools or validation of existing tools is essential for the ongoing transition to a competency-based curriculum.
