Examples of intervention mapping following the behavior change wheel.

Constructs/mechanisms of action targeted	Intervention function	BCTsa	Intervention components and modes of delivery
Memory, cognitive overload, and behavioral regulation	Enablement	Conserve mental resources, feedback on behaviors, and self-monitoring	Use wearable trackers to automatically monitor sitting time, and an app provides daily feedback to enable user to self-monitor day-to-day changes in break patterns.
Belief about capabilities	Education	Feedback on behaviors	An app presents daily summary of and feedback on the sit-break pattern.
Prospective memory, cognitive overload, and goal priming	Environmental restructuring	Conserve mental resources, prompts and cues, and add objects to the environment	Add or augment objects that facilitate the performance of breaks; use the object to cue breaks naturally associated with the object (eg, augment a cup to cue tea breaks).
Breaking habit, self-efficacy, and implementation intention (goal accessibility)	Enablement	Action planning	Researcher guides the person to set up plans to combat prolonged sitting by specifying the frequency and duration of breaks, including developing “if-then” rules that use an IoT object as the cue.
Habits and contingencies	Training	Habit formation	Researcher guides the person to develop automatic responses to the introduced stimuli (the IoT object) through repetition.
