The diary component of SHIFT focused on intensively measuring and examining the fluctuations and co-occurrence of mood, stress, substance use and sexual behavior among undergraduates at Columbia. Data from the diary will be used to explore variation in measured variables over time and help the team understand how processes unfold over days and weeks. Each day for 60 days between October-December 2015, over 400 Columbia undergraduates took the same brief web-based questionnaire assessing the above mentioned factors. Students accessed the diary between 4pm-4am each day via a web-based portal, accessible via phone, tablet or computer. Students were sent at least 1 daily text message reminder to complete the diary. The team is currently analyzing the data.
