Welcome to the Digital Marshmallow Test!

The Digital Marshmallow Test app (DMT mPulse), powered by Appleā€™s Researchkit, is a collaborative effort between Northwell Health, Cornell Tech, and Sage Bionetworks. The smartphone app uses brief surveys and game-like tasks to collect information on thoughts, feelings, and behaviors across different situations. The app also collects information on how you use your phone, including battery life. We hope that gathering this information will lead to meaningful advances in learning to help individuals who sometimes have difficulty regulating their behavior or act impulsively in certain situations.

If you would like to test the app, please do the following:

  1. Download the app from the App Store

    (Note: You must have the latest OS installed on your phone in order to maximize user experience.)
  2. Follow the on-screen instructions to sign in

  3. Complete the Baseline Assessment

  4. Take brief surveys and play mini-games in the morning and evening every day for one week

  5. Complete the Day 7 Assessment

  6. Send your completion code via email (separate from your data) and earn a $25 Amazon gift card
