The BCD cards were grounded on two well-established theoretical models of behavior: the Transtheoretical Model (TTM)
of behavior change and the Behavior Change Techniques Taxonomy (BCT taxonomy). By condensing the BCT taxonomy to a set
of 34 behavior change techniques that are applicable to the design of digital interventions, the BCD cards provide
an easily accessible repertoire of theoretically and empirically grounded behavior change techniques for interaction designers.
Using the TTM of behavior change, and particularly the stages and processes of change, the BCD cards provide a way to structure designers'
efforts, inviting them to tailor their intervention to particular stages of change and to consider the specific challenges and
the purpose the intervention can serve in each stage. By mapping the 34 techniques to the five stages of change, we support designers
in selecting the behavior change techniques that are most appropriate to a given stage.
