Health behavior theories assist in understanding health behavior problems, developing intervention based on salient determinants that affect behaviors and evaluating the effectiveness of the health interventions. The most effective persuasive interventions for behavior change usually occur when the intervention is behaviorally focused and theory driven(Consolvo, McDonald, & Landay, 2009).Therefore, persuasive technology can be made optimally effective, if they are also combined or supported by behavior change theories (Shegog, 2010). Since, the aim of this research is to design a persuasive technology in line with individual’s health goals. The use of any of these model could drive the intervention-tool to be a user-centered.
