Validity and Validation in Social, Behavioral, and Health Sciences

“This book discusses validity theory and validation practices across different disciplines, an important endeavor because testing is used for making individual and public policy decisions. … This well-written book addresses an important topic, since so many fields depend on tests and measurements to make critical decisions. It is a good resource for researchers and test users.” (Gary B. Kaniuk, Doody’s Book Reviews, March, 2015)

“This book by Zumbo and Chan is recommended for professionals working on development and validation of tests and measures and for researchers investigating on outcomes based on these instruments, because it discloses how things should be made in this matter and how really they are not.” (Pablo Martinez-Martin, Applied Research in Quality of Life, Vol. 10, 2015)

Bruno D. Zumbo (Ph.D.) is Professor of Measurement, Evaluation, & Research Methodology with additional appointments in the Department of Statistics and the Institute of Applied Mathematics at the University of British Columbia (UBC) in Vancouver, British Columbia, Canada. Prior to arriving at UBC in 2000, he held Professorships in the Departments of Psychology, Education, and Mathematics at the University of Ottawa and then the University of Northern British Columbia. Over the last 25 years his interdisciplinary program of research has emerged to have broad interdisciplinary impact and as such is well-recognized in a variety of disciplines including psychology, applied social science research (quality of life and well being), assessment, educational research, language testing, health and human development. His research on validity and validation is at the core of his program of research and has elements of working at the foundations of the discipline, including philosophy of science, scientific methodology as well as practical psychometric methods at the intersection of measurement, statistical science and mathematics. Professor Zumbo's research and teaching have been recognized with international awards. He was recipient of the 2005 Samuel J. Messick Memorial Lecture Award for his work in validity, 2010 Research Fellow Award by the International Society for Quality of Life Studies and 2011/2012 UBC Killam Teaching Prize. He was also selected as a Fellow of American Educational Research Association (AERA) in 2011.Eric K. H. Chan (Ph.D.) received his doctorate from the University of Calgary in Mental Health and Counseling and completed his post-doctoral training in the Measurement, Evaluation and Research Methodology (MERM) Program at the University of British Columbia (UBC) under the supervision of Professor Zumbo. Eric specializes in psychometric methods, knowledge synthesis (systematic review and meta-analysis) and patient- (and client-) reported outcome measures (PROM) and patient- (and client) reported experience measures (PREM) and consulting. He currently holds a prestigious Fellowship with the Technology Evaluation in the Elderly Network (TVN), with a focus on establishing consensus-based best practice guidelines for the selection and utilization of PROMs and PREMs to inform heath care. Prior to his fellowships he held a research appointment at the Canadian Council on Learning, where he conducted and provided advice on a number of systematic review and meta-analytic projects for policy decision making.
