This is a doctoral level seminar that provides an overview of behavioral decisional theories (e.g. rational choice, multiattribute utilities models, naturalistic decision making, ethnographic decision models, Janis and Mann's conflict theory, information processing theory, heuristic models, process tracing models, etc.) and examines research applications of those theories to the health of older adults. Research focuses on decision made by physicans, older adults, caregivers and policy makers. A variety of applications include such decision domains as preventative screening, retirement and financial planning, other medical treatments, self-care, seeking medical care, institutionalization, end-of-life, etc.
