This thesis deals with persuasive design. The result of this research was motivated by the quest for understanding the different dimensions or categories of analysis that influence or even determines changes in human behavior through the use of product designs. A transdisciplinary vision was the departure research posture in order to understand the full human behavioral dimensions playing a role in human behavioral changes. This stance recognizes the human behavior as a result of internal forces that shapes the individuals intentionality and external forces that constrain and determines the final behavior. This thesis intent to answer the main question about, which are the conceptual dimensions involved in behavioral change through the use of a product design that persuades people into the new behavior? The hypothesis thus defines the existence of external forces to the product that influence and determines the result of an intended change in human behavior through the use of product design. These external forces are defined as conceptual dimensions that must be taken into account when designing products with the intent of provoking a human behavioral change. The use of the Grounded Theory approach allowed studying a singular phenomenon and generating categories of analysis through theoretical sampling. The research focuses on the actual situation where a product design is involved in a human behavioral change. The research focused on the use of the bicycle as transportation system in Mexico City as a way to facilitate the observations in a single situation. A series of interviews to product users were applied and through the use of theoretical sampling a number of specific categories were identified thus building the final persuasive model. The research final result and the value for the design discipline is made explicit through a persuasive model proposal that defines the different dimensions on human behavior as categories that determines and influence human behavioral changes. The persuasive model proposed in this research contemplates the external categories that determine human behavior that are present in the context as well as in the individuals mind and the categories or product design properties that influence human behavioral changes. The research generated value towards the design discipline includes the persuasive model and a startup guide for its use during the design project process.
