Abstract and Keywords

Volumes of research and countless models have examined how people decide to make a health-behavior change. This chapter is focused on what happens after the decision to change is made. Do people maintain the changes they initiate? In other words, how do people commit to the new healthier behavioral choice? Often, the factors that push a person to make the change may be the same factors that help the person maintain the change. We discuss how, in fact, there may be a paradoxical inverse relationship. A number of theories are examined and applied to behavior maintenance. These include borrowing from both the commitment literature with Rusbult’s Investment Model of Commitment, as well as the health-behavior-change literature, such as the Theory of Planned Behavior, the Health Belief Model, and the Transtheoretical Model. We also examine the concepts of approach and avoidance motivation and goal orientation. Discussion of these models and future directions conclude this chapter.

Keywords: health-behavior change, commitment, behavioral maintenance, Investment Model, Theory of Planned Behavior, Health Belief Model, Transtheoretical Model, approach/avoidance orientations, self-efficacy, self-regulation
