SARA - Substance Abuse Research Assistant

Memes/Gifs: Immediately after completing their daily ecological momentary assessment using the app, each participant is randomized to receive an inspirational or funny meme or gif that is displayed within the app. Life Insights: Immediately after completing both daily active tasks using the app, each participant is randomized to unlock a life insight. Life insights track data provided by the participant, are stored in a virtual library within the app, and are regularly updated with recent data points.

Reminder Push Notifications: All participants receive a push notification reminder from the app at 6pm (the time at which data collection opens) to complete their daily data collection activities. Each day, each participant will be randomized to receive either a generic reminder or a reminder that contains more detailed information (e.g., about upcoming incentives). Inspirational Push Notifications: Each day, each participant will be randomized to receive a push notification at 4pm that contains inspirational song lyrics or celebrity quotes.
