DRAFT 1 Using Behavior Modification Theory to Understand and Guide Technological Interventions

Interactive behavior change technology (IBCT) has shown great promise for people with diabetes as a supplemental resource that will support them as they take health actions to manage their disease and work to prevent long term complications. IBCT may include the use of pervasive devices (such as mobile phones, personal digital assistants and sensing devices), as well as pc based and internet based applications. A study of existing IBCT for diabetes revealed “only one third of the studies had incorporated behavioral theories or models into the interventions.” [61] We believe that interactive technologies designed with the intent of changing health behavior will be more effective if they are grounded in the relevant theory. The purpose of this chapter is to introduce three of the most widely used behavior modification theories, demonstrating how they may be used to evaluate and assist in the design of IBCT.
