ABSTRACT
The self-as-doer is introduced as a self-schema that specifically addresses motivation for behavioral engagement and the maintenance of behavioral change. The self-as-doer is presented as a construct that aims to describe individuals in terms of their identification with doing a behavior. Throughout this chapter, the self-as-doer construct is described in detail through discussion of its foundational theories including the identity theory and how it is different from other motivational and health theories (e.g., self-determination, self-efficacy, habit, locus of control, and outcome expectancies). Foundational research on the self-as-doer is also reviewed to further describe unique attributes of the self-as-doer. The purpose of this chapter is to introduce the self-as-doer theory and why it is important to consider as a critical theory in health promotion and maintenance.
