Final answer:
The Stages of Change Model, also known as the Transtheoretical Model of Behavior Change, was developed by James O. Prochaska and Carlo C. DiClemente in the late 1970s and early 1980s. It describes a series of stages individuals go through when changing behavior.
Step-by-step explanation:
The Stages of Change Model, which is pivotal in understanding the processes people go through to change their behavior, was not developed by Erik Erikson, Walt Rostow, nor by the contributors to social change movements. While Erikson developed a theory of personality development, Rostow outlined the stages of economic growth, and various sociologists and psychologists worked on understanding social movements, the Stages of Change Model refers specifically to the Transtheoretical Model of Behavior Change. This model was developed by James O. Prochaska and Carlo C. DiClemente in the late 1970s and early 1980s. They identified a series of stages individuals go through when changing behavior: precontemplation, contemplation, preparation, action, and maintenance.
