Foundational knowledge - Behavioral Intervention Technology (BIT) model

5. When

This component refers to the workflow of the intervention and defines under what conditions the intervention is delivered. Some common examples of workflow elements are: (1) tunnelling – the use of data to decide which interventions meet the needs and preference of users in a specific time period; (2) frequency – how frequent the intervention is offered; (3) conditions – the use of data to determine when should an intervention be delivered (it can be time-based, task-completion, and event-based); (4) user-defined – offers access to all elements of the intervention from the beginning, allowing the user to set the sequence and timing of the app (Mohr et al., 2014). Usually, workflows integrate a number of these elements to achieve behavior change, depending on the needs of the interventions and the characteristics of the users (Mohr et al., 2014).
