Ecological momentary assessment (EMA) entails taking surveys multiple times daily on a smartphone. EMA has been widely used to monitor moment-to-moment fluctuations in thoughts, feelings, and behaviors as they occur naturally in one's environment. The current study investigated how depression, productivity, and sleep, fluctuate across time and how these variables covary together in undergraduate participants using EMA for two weeks. Participants were either assigned to EMA which included items about mindfulness (Mindfulness-EMA) or without mindfulness items (No-Mindfulness EMA). Participants were asked to report upon current depression, stress, irritability, productivity, fatigue, and sleep, up to three times daily. Multilevel modeling was used to examine trajectories of change and how variables may increase or decrease over the span of two weeks. The sample (n=103) included 60.9% female, 37% non-white, and 11% Latino/Hispanic participants, with a mean age of 19 (SD = 1.24). Nearly half (47.8%) were freshmen. Preliminary analyses reveal a significant time effect for stress (p=.000); anxiety (p=.001); irritability (p=.002); and sleep disturbances (p=.004), such that all variables improved over two weeks for all participants. Fatigue, depression, and dissociation did not significantly change. Subsequent analyses will examine how trajectories of change covary by demographics, such as sex and year in college.
