Development Of The Biostatistics And Clinical Epidemiology Skills Assessment For Medical Residents, Patrick Brian Barlow

Doctoral Dissertations

This study developed the Biostatics and Clinical Epidemiology Skills (BACES) assessment, and established its preliminary item characteristics and validity evidence. Unlike previous instruments, the BACES assessment was developed and tested using an item response theory (IRT) approach to measurement to create a new, adaptive biostatistics and clinical epidemiology knowledge assessment for graduate medical professionals. Thirty multiple-choice questions were written to focus on interpreting relevant examples of clinical epidemiology and statistical methods. A four person expert panel reviewed these items for content validity. After this review, the BACES assessment was administered to 147 medical residents across three academic medical centers. Results …
