Calm + Oura Sleep Study

This is a quasi-experimental study with pre-post assessment using a convenience sample of Calm and Oura employees. We will employ two weeks of baseline data collection and administer the intervention for four-weeks. Participants will be randomized to one of three groups (i.e., general meditations, sleep meditations, or Sleep Stories). Self-report assessments will be conducted during baseline periods and during week 1 and week 4 of the intervention. Sleep diaries and objective (i.e., Oura ring and Calm app) usage data will be collected on a continual basis during intervention. The purpose of this study is to: 1. Test the preliminary effects of using Calm (daytime vs nighttime) for four weeks on sleep outcomes (sleep quality, sleep onset, sleep efficiency, number of nighttime awakenings, total sleep time) using self-report and objective measures. 1. Self-report: Sleep diaries, pre-sleep arousal (Pre-Sleep Arousal Survey), fatigue (Fatigue Severity Scale), daytime sleepiness (Epworth Sleepiness Scale), insomnia (Insomnia Severity Index), sleep quality (Pittsburgh Sleep Quality Index) 2. Objective: Oura ring (sleep onset, sleep efficiency, number of nighttime awakenings, total sleep time, REM/light/deep sleep). 2. Test the preliminary effects of using Calm (daytime vs nighttime) on neurophysiological outcomes \[heart rate variability (HRV), heart rate, respiratory rate\] as measured by the Oura ring during meditation and after four-weeks of mobile meditation practice.
