Development of a theory-driven, webbased behavioral change support system for environmentally friendly mobility behavior

While the internet has long been used for commercial ends, its use as communication medium or distribution channel in order to promote environmentally friendly behaviors is rather uncommon up to now. The paper gives an overview of those technological features of mobile applications and the Web 2.0 that seem relevant from an intervention perspective as well as experience that have been made so far with such web-based support systems. One important conclusion is that web-based interventions, too, can only be effective when adequately informed by behavioral theory. The Stage Model of Self-Regulated Behavioral Change (Bamberg, 2013a, 2013b) provides a framework that is suited for the development of dynamic and interactive web-based interventions. The main part of the article gives a detailed overview of how the model can be used to develop a web-based support system to promote environmentally friendly everyday mobility behavior.
