Screenshots of BREATHE’s ecological momentary assessment phone app. (A) A notification pops up on the smartphone at certain times throughout the day to collect information on symptoms, or if a sensed event triggers a specific survey. (B–D) To engage younger children in answering the surveys, gamification is employed, including the use of an animated dragon the user personally names when first starting the app. The pet dragon can be “fed” and kept happy whenever a survey is successfully answered, resulting in rewards.
