SNAPSHOT Study

The SNAPSHOT study seeks to measure Sleep, Networks, Affect, Performance, Stress, and Health using Objective Techniques. It is a NIH-funded collaborative research project between the Affective Computing group, Macro Connections group, and Harvard Medical School's Brigham & Women's hospital. We have been running this study since fall 2013 to collect one month of data from 50 MIT undergraduate students who are socially connected every semester. We have collected data from about 170 participants, totaling over 5,000 days of data. We measure physiological, behavioral, environmental, and social data using mobile phones, wearable sensors, surveys, and lab studies. We investigate how daily behaviors and social connectivity influence sleep behaviors, health, and outcomes such as mood, stress, and academic performance. Using this multimodal data, we are developing models to predict onsets of sadness and stress. This study will provide insights into behavioral choices for wellbeing and performance.
