Identity processes during health behavioral change

To what extent and how do identity processes influence health behavior?

This project focuses on  the identity processes that accompany health behavioral change. Main premises of the theoretical framework we apply is that over time a behavior, such as smoking, is likely become integrated in the identity of a person. When this happens, behavior becomes robust to change because it is so closely linked to central self-views. Thus, this research is based on the contention that behavioral change can only then occur if the new (healthier) behavior becomes part of the “self”: the person one perceives oneself to be, or wishes to be. Such views of the self need to be vivid  and readily accessible, particularly at times when one is faced with difficulties that interfere with establishing a new behavioral pattern.

We examine behavioral change as it occurs over time and search for self-defining moments during the process. We also experimentally induce new identities, and try to encourage people to link a behavioral goal, such as continuing or quitting smoking, to (un)desired future self-views, or so-called Possible Selves (Markus & Nurius, 1986).
