Behavior change is often a goal for staff working directly with constituents, organizations, governments,
or communities. Individuals charged with this task can be thought of as “interventionists” whose goal it is
to design and implement programs or interventions that produce the desired behavioral changes1 (Glanz,
Lewis, & Rimers, 1990, p. 17). As Glanz, Lewis, and Rimmers1 suggest, designing interventions to yield
behavior is best done with an understanding of behavior change theories and an ability to use them in
practice (1990, p. 19). The goal of this Gravitas, therefore, is to introduce three major theories of behavior
change, describe the key variables of behavior change models, and to explore the link between behavior
change and attitude
