THE BCD CARDS

A card-based design support tool that supports the design of behavior change Technologies.

Stage Cards

The 5 Stage Cards are devoted to Prochaska’s et al. Transtheoretical Model of Behavior Change and, particularly, the 5 stages of behavior change. The front-side provides the description of the stage, while the backside lists design considerations and hints. Each stage card is presented with a discrete color, in an effort to make the technique-stage mapping easier.

Technique Cards

Each of the 34 technique cards, presents a behavior change technique, derived from Michie’s et al. taxonomy, and mapped to one or more of the five stages of behavior change that the technique is relevant to. The front-side provides the description of the technique along with an example intervention, while the back-side lists design considerations and hints that aim to trigger discussion among the members of the design team.

"Define the Problem" exercise

To provide a starting point, we adopted Michie’s et al. “define the problem” exercise which asks designers to define and reflect on the behavior to be changed and its constituents.
