Over seven days participants were prompted with several questions (four times per day) about their desire for social interactions, and the quality of interactions that occurred. In addition, we assessed GPS, Bluetooth, accelerometer, and ambient audio recordings of participant daily life. These data allowed for passive data collection which can help us identify which participants are more socially isolated, and how that data may differ from self-reported social isolation. In this pilot study, participants found the Ethica app easy to use and non-intrusive to their daily activities. We have begun to analyze the cell phone objective data to identify key differences in our participant groups.
