Kevin Kennedy is pursuing a Ph.D. in the Health Research Methodology program at McMaster University. He began his studies in Psychology at Carleton University while working for the Public Service Commission as an analyst. He made the full time commitment to research in pursuit of his Master’s degree in Experimental Psychology at Laurentian University. For his Master’s, he studied regression techniques and psychometric validation, where he explored how clinical psychologists utilised decision support systems when making decisions on correctional officer candidates for their psychological suitability. Currently, Kevin is continuing work in psychometrics for applications in health care, establishing the psychometric validity of a disease-specific preference-based measures of health related quality of life for glaucoma (HUG-5). His doctoral research reviews common economic preference elicitation techniques (standard gamble, time trade-off), and contrasts utility functions with Louviere’s Best-Worst Scaling technique for disease-specific and generic measures of health related quality of life.
