Relationship between behavior Fogg model and behavior change technique taxonomy 93: Implications for behavior designers

Abstract

BCT taxonomy v1 is an extensive taxonomy of 93 consensually agreed, distinct Behavior Change Technics (BCTs). The BCT taxonomy offers a step change as a method for specifying interventions and becomes a very useful way to systematize a set of 93 BCT that have been developed thorough a Delphy study by Michie. The Behavior Fogg Model (BFM) explains in an elegant and easy way how behavior happens when three elements converge at the same moment: Motivation, Ability, and Prompt. Thus, BCT inventory is the most exhaustive and well-validated set of behavior change techniques that any researcher/professional can use both to analyze psychological interventions, with and without technology use. On the other hand BFM allows researchers and practitioners to design intervention in which the behavioral change techniques have a key role and allow researchers/professionals to analyze the "persuasibility" of an intervention. In this framework, our research question were: Could we find a relationship between BFM and BCT Inventory? Could we classify the 93 BCT's in the three "dimensions" of BFM model? Methods. Two researchers classified the 93 BCT's V1 in three categories following an ad-hoc criterion: D1 Motivation, D2: Ability and D3: Prompt. Results showed that it is possible to categorize the 93 BCT's techniques in the dimensions of Ability, Motivation and Prompt of BFM. Analyzing the 93 BCT's we concluded that it exists more techniques related to "Motivation" and "Prompt" Dimensions, that with "Ability" Dimension. Conclusion. We need further research to analyze the implication in psychological intervention aimed to change behaviors. As first conclusion we considered that since Fogg considers that the Ability dimension increases the adoption of a specific behavior it would be useful to make a reflection about how to increase the number of BCT's related with Ability dimension in our interventions.
