The purpose of this research study is to assess the links between personality, daily positive and negative events, sleep quality, and cardiometabolic markers in daily life. We hope to use the results of this study to inform interventions to improve daily mood and sleep quality. Participation in this study would have four parts. If you meet inclusion criteria, first you would be asked to take a baseline survey online; then you would be asked to complete a daily survey component that consists of a short in-person training session followed by 14 days of short daily surveys, during which time you would be asked to wear a non-invasive actigraphy watch (similar to a FitBit); finally, you would be asked to come in for one final in-person visit for a blood draw to assess cardiometabolic factors related to stress. In total, it is expected that the entire study (baseline survey, training session, daily survey completion, and cardiometabolic session) should take you approximately 6.5 hours, spread over the course of a few weeks. It is emphasized that your participation is voluntary. You will not be penalized in any way for not participating, or for dropping out at any point throughout the study.
