Health Behavior Change (HBC) refers to facilitating changes to habits and/or behaviors related to health. There are a number of models/theories of HBC, which provide a structured framework to better understand the HBCs of individuals. The Transtheoretical Model (TTM, aka "the Stages of Change" model) is an integrative model used to conceptualize the process of intentional behavior change and is applied to a variety of behaviors, populations, and settings. In the last few years, use of TTM by the profession of audiology has been increasing.
