Developing Computerized Adaptive Testing for a National Health Professionals Exam: An Attempt from Psychometric Simulations.
Introduction: The accurate assessment of health professionals' competence is critical for ensuring public health safety and quality of care. Computerized Adaptive Testing (CAT) based on the Item Response Theory (IRT) has the potential to improve measurement accuracy and reduce respondent burden. In this study, we conducted psychometric simulations to develop a CAT for evaluating the candidates' competence of health professionals.
Methods: The initial CAT item bank was sourced from the Standardized Competence Test for Clinical Medicine Undergraduates (SCTCMU), a nationwide summative test in China, consisting of 300 multiple-choice items. We randomly selected response data from 2000 Chinese clinical medicine undergraduates for analysis. Two types of analyses were performed: first, evaluating the psychometric properties of all items to meet the requirements of CAT; and second, conducting multiple CAT simulations using both simulated and real response data.
Results: The final CAT item bank consisted of 121 items, for which item parameters were calculated using a two-parameter logistic model (2PLM). The CAT simulations, based on both simulated and real data, revealed sufficient marginal reliability (coefficient of marginal reliability above 0.750) and criterion-related validity (Pearson's correlations between CAT scores and aggregate scores of the SCTCMU exceeding 0.850).
Discussion: In national-level medical education assessment, there is an increasing need for concise yet valid evaluations of candidates' competence of health professionals. The CAT developed in this study demonstrated satisfactory reliability and validity, offering a more efficient assessment of candidates' competence of health professionals. The psychometric properties of the CAT could lead to shorter test durations, reduced information loss, and a decreased testing burden for participants.
期刊介绍：
Perspectives on Medical Education mission is support and enrich collaborative scholarship between education researchers and clinical educators, and to advance new knowledge regarding clinical education practices.
Official journal of the The Netherlands Association of Medical Education (NVMO).
Perspectives on Medical Education is a non-profit Open Access journal with no charges for authors to submit or publish an article, and the full text of all articles is freely available immediately upon publication, thanks to the sponsorship of The Netherlands Association for Medical Education.
Perspectives on Medical Education is highly visible thanks to its unrestricted online access policy.
Perspectives on Medical Education positions itself at the dynamic intersection of educational research and clinical education. While other journals in the health professional education domain orient predominantly to education researchers or to clinical educators, Perspectives positions itself at the collaborative interface between these perspectives. This unique positioning reflects the journal’s mission to support and enrich collaborative scholarship between education researchers and clinical educators, and to advance new knowledge regarding clinical education practices. Reflecting this mission, the journal both welcomes original research papers arising from scholarly collaborations among clinicians, teachers and researchers and papers providing resources to develop the community’s ability to conduct such collaborative research. The journal’s audience includes researchers and practitioners: researchers who wish to explore challenging questions of health professions education and clinical teachers who wish to both advance their practice and envision for themselves a collaborative role in scholarly educational innovation. This audience of researchers, clinicians and educators is both international and interdisciplinary.
The journal has a long history. In 1982, the journal was founded by the Dutch Association for Medical Education, as a Dutch language journal (Netherlands Journal of Medical Education). As a Dutch journal it fuelled educational research and innovation in the Netherlands. It is one of the factors for the Dutch success in medical education. In 2012, it widened its scope, transforming into an international English language journal. The journal swiftly became international in all aspects: the readers, authors, reviewers and editorial board members.
The editorial board members represent the different parental disciplines in the field of medical education, e.g. clinicians, social scientists, biomedical scientists, statisticians and linguists. Several of them are leading scholars. Three of the editors are in the top ten of most cited authors in the medical education field. Two editors were awarded the Karolinska Institute Prize for Research. Presently, Erik Driessen leads the journal as Editor in Chief.
Perspectives on Medical Education is highly visible thanks to its unrestricted online access policy. It is sponsored by theThe Netherlands Association of Medical Education and offers free manuscript submission.
