3. What

This component of the BIT model refers to the actual behavioral intervention technologies the intervention offers to prompt behavior change. These can take the form of a data field for logging in the desired behavior (e.g. food consumption, sleep hours, etc.) to act as a behavior change strategy of monitoring (Mohr et al., 2014). Other examples of behavioral intervention strategies are notifications, app reports for users, logs, and visualizations; these elements are delivered separately or embedded together (Mohr et al., 2014).
