Brief summary

This pilot study will evaluate the feasibility of a 6-week intervention using Chorus Sleep's ios app to improve sleep quality, reduce stress, and reduce depression and anxiety using a randomized controlled design.

Detailed description

Chorus Sleep is a successful wellness company with a loyal and growing clientele, and considerable qualitative and anecdotal evidence for its efficacy at reducing stress, and improving sleep quality. It builds upon existing meditation and mindfulness practices with well documented efficacy for reducing pain, improving mental health, and reducing stress. Further its innovative approach - including the use of popular music and breathwork patterns that elicit stimulating and novel sensations and physiological activity - may removes barriers to participation and engagement of many traditional meditation and mindfulness practices. Prior research evaluating the efficacy of audio meditation using the Calm app found use of the app for eight weeks significantly decreased daytime fatigue and sleepiness and pre-sleep arousal compared to a wait-list control group. Further, use of the calm app for 8 weeks was associated with greater improvements in depression and anxiety symptoms, and those effects were mediated by lower pre-sleep arousal. This study will investigate whether Chorus Sleep's innovation in auditory app-based sleep inventions will demonstrate similar efficacy. This study has the following objectives: 1. Pilot a randomized controlled trial on Chorus sleep to evaluate feasibility. 2. Evaluate the effect of Chorus sleep practice at improving sleep quality. 3. Evaluate the effect of Chorus sleep practice at reducing perceived stress, depression, and anxiety, both directly and indirectly through improved sleep quality. 4. Characterize habit formation of Chorus sleep practice

Interventions

During the 6-week intervention, participants will receive daily reminders to complete their daily sleep log and a link to a chorus sleep class for them to listen to that night. The daily sleep class involve listening to 15 minute audio sessions, which include guided mediation and breathing exercises.

Design outcomes

Primary

MeasureTime frameDescription
Preliminary effects of the Chorus Sleep app on sleep related impairment, as assessed by changes in participants' self-reported sleep related impairment from pre- to post- 6-week intervention periodWithin 24 hours pre-and within 1 week post- 6 week interventionChange in total score on the PROMIS Sleep Related Impairment Scale from baseline to 6-week follow-up. Mean scores across the 8 items will be used. Items are a 5-point scale from 1-5. Therefore, the range of possible change scores is from -4 to 4, where a lower negative score corresponds with greater decreases in sleep disturbance, a higher score corresponds with greater increases in sleep disturbance, and 0 indicates no change.

Secondary

MeasureTime frameDescription
Change in perceived stressWithin 24 hours pre-and within 1 week post- 6 week interventionChange in perceived stress on the Perceived Stress Scale-10 from baseline to 6-week follow-up. Mean scores across the 10 items will be used. Items are on a 5-point scale from 1-5. Therefore, the range of possible change scores is from -4 to 4, where lower negative scores correspond with greater decreases in perceived stress, higher positive scores correspond with greater increases in perceived stress, and 0 indicates no change.
Change in depression symptomsWithin 24 hours pre-and within 1 week post- 6 week interventionChange in depression symptoms on the PROMIS® Item Bank v1.0 - Emotional Distress - Depression-Short Form 8a from baseline to 6-week follow-up. Mean scores across the 8 items will be used. Items are on a 5-point scale from 1-5. Therefore, the range of possible change scores is from -4 to 4, where lower negative scores correspond with greater decreases in depression, higher positive scores correspond with greater increases in depression, and 0 indicates no change.
Change in anxiety symptoms from baseline to 6-week follow-up.Within 24 hours pre-and within 1 week post- 6 week interventionChange in anxiety symptoms on the PROMIS® Item Bank v1.0 - Emotional Distress - Anxiety - Short Form 8a from baseline to 6-week follow-up. Mean scores across the 8 items will be used. Items are on a 5-point scale from 1-5. Therefore, the range of possible change scores is from -4 to 4, where lower negative scores correspond with greater decreases in anxiety, higher positive scores correspond with greater increases in anxiety, and 0 indicates no change.
Demand, based on frequency of use of the Chorus Sleep appRecorded continuously throughout 6-week interventionThe percentage of days in which participants use the chorus sleep app over the course of the 6 week study period.

Other

MeasureTime frameDescription
Daily self-reported sleep disturbance, as measured by number of awakenings on the in-app sleep surveyRecorded daily throughout the 6 week intervention (intervention group only)Daily reports of number of awakenings on the in-app sleep survey with options from 0-more than 4 times in increments of 1.
Daily self-reported sleep disturbance, as measured by total time awake on the in-app sleep survey.Recorded daily throughout the 6 week intervention (intervention group only)Daily reports of number of awakenings on the in-app sleep survey with the following options: 0-30 minutes, 31-60 minutes, 1-2 hours, 2 or more hours
Habit formationwithin 1 week post- 6 week interventionHabit formation for using the Chorus Sleep App will be measured using an adaptation of the Self-Report Behavioral Automaticity Index. Mean scores will be used across 4 items. Possible scores range from 1-5, where higher scores indicate greater automaticity.
Daily self-reported sleep disturbance, as measured by time to fall asleep, on the in-app sleep survey.Recorded daily throughout the 6 week intervention (intervention group only)Daily reports of time to fall asleep reported on the in-app daily sleep survey with options: Fell asleep within 15 minutes, Fell asleep within 16-30 minutes, Fell asleep within 31-60 minutes, Fell asleep after 60 minutes.
