Biostatistics Seminar Series: Chengwu Yang, MD, MS, PhD

Chengwu Yang, MD, MS, PhD Measurement Specialist, Office for Scholarship in Learning and Education Research Assistant Professor of Biostatistics, Department of Public Health Sciences College of Medicine, The Pennsylvania State University   Abstract:  Measurement Instruments (a.k.a., Scales) such as the Mini-Mental Status Examination (MMSE) are widely used in medicine to measure subjective outcomes such as Cognition. However, in medicine "most scales were not professionally developed" (Teresi & Fleishman, 2007). Thus, a crisis exists in the field of Measurement in Medicine (MIM). Fortunately, recent movements of Patient-Centered Research (PCR) led by the NIH / PCORI / FDA offered tremendous opportunities to change the MIM from a crisis to a gold mine. This presentation will review the current situation of MIM, focusing on co-existing dangers and opportunities, with summaries of future directions. Along the way, 14 research projects will be demonstrated with grants and papers in diverse fields, including but not limited to Clinical Medicine, Medical Education, Hospital Administration, Radiology, Neurology, and Psychiatry.
