This study investigates the feasibility and effects of a mindfulness meditation mobile application on sleep for individuals reporting sleep disturbances.
The purpose of this study is to investigate the effects of a mindfulness meditation mobile application on sleep in individuals reporting sleep disturbances.
The investigator's guiding hypothesis is that the combined elements of a consumer-based mobile meditation app, Calm (e.g., daily mindfulness meditation, sleep stories and behavioral components), will be feasible, accepted and associated with sustained improvement in sleep among individuals who self-identify as having sleep disturbances. Calm provides daily, 10-minute, guided meditations grounded in mindfulness-based stress reduction (MBSR) and Vipassana meditation. Uniquely, Calm also offers "Sleep Stories", developed using techniques from Cognitive Behavioral Therapy and Relaxation Technique.
This is a randomized control feasibility study with an intervention and waitlist control.
Aim 1: Examine the feasibility of using a consumer-based mindful meditation app for >10 mins/day over eight weeks for 100 adults who self-identify as sleep disturbed.
Aim 2: Explore the preliminary effects of Calm on sleep disturbance and emotional symptoms associated with sleep disturbance (i.e. stress, anxiety, depressive symptoms) as compared to those in a wait-list control group.
Recruitment: Participants will be recruited nationally via Internet-based strategies including social media (e.g. Facebook, Twitter, Instagram), social networking sites and email listservs. Recruitment flyers will be posted on social media websites. ResearchMatch.org will be also be utilized as a recruitment tool for this protocol.
Eligibility: Inclusion criteria are: (1) self-identify as sleep disturbed (i.e., score >10 on the Insomnia Severity Index), (2) >18 years of age, (3) English speaking, (4) willing to download the Calm app to their smartphone, and (5) have not practiced meditation more than 60 minutes a month in the past six months (6) willing to be randomized. Participants will report use of medication for sleep at baseline, mid-intervention and post-intervention and not excluded for medication.
Enrollment: Interested participants will complete a brief (5-10 minute) eligibility screener via Qualtrics. Participants will not be made know of sponsor name before randomization assignment to avoid disclosing the app that they will be using. Eligible participants will be asked to sign an electronic informed consent prior to the start of the intervention. After informed consents have been completed, participants (N=100) will be identified. Once eligible participants have been identified, they will be emailed instructions. Ineligible participants will be notified by email.
Tracking: Intervention participants (n=50) usage will be continuously tracked throughout the intervention by Calm.
Post-intervention: Post-intervention questionnaire will be emailed to intervention and control participants via a link from Qualtrics. All participants will have access to Calm after the 8-week study period, but will not be asked to meditate.

| Calm | Experimental | The intervention will occur across 8 weeks. During Week 1, it is suggested to intervention participants that they complete "7 days of Calm" meditation series (7 meditations, each approximately 10 minutes long, created to help users learn the basics of mindfulness meditations. For the remaining weeks (Week 2- Week 8) intervention participants will be asked to meditate for 10 minutes per day using any of the meditation sessions/features. Throughout the intervention, participants not completing 30 minutes of meditation per week will be sent reminders texts/emails. |
|
| Control | No Intervention | This group is a wait-list control group who will receive the intervention following the 8-week waiting period. Participants in this condition are instructed not to start meditating before the waiting period. After the 8-week waiting period, waitlist participants will receive the same intervention as described in the Calm Arm. |

| Calm | Behavioral | Calm provides daily, 10-minute, guided meditations grounded in mindfulness-based stress reduction (MBSR) and Vipassana meditation. Calm also offers "Sleep Stories," developed using techniques from Cognitive Behavioral Therapy and Relaxation Technique. Clam also includes behavioral components to reinforce sustained practice. |
| Measure | Description | Time Frame |
|---|---|---|
| Acceptability, as measured by participants' satisfaction with the content in the mindful meditation app | Participants' satisfaction will be measured by participant responses to the item, "On a scale of 1-5 (1=did not enjoy at all, 5=very much enjoyed), how would you rate your overall enjoyment with using Calm (i.e., likeable, pleasurable)?" on an investigator-developed survey. Participants rate their satisfaction on a five-point scale, ranging from 1 (did not enjoy at all) to 5 (very much enjoyed). | Participant satisfaction is measured immediately after the the conclusion of the 8-week intervention. |
| Acceptability, as measured by participants' perceptions of the appropriateness of the content in the mindful meditation app | Participants' perceptions of appropriateness will be measured using six items on investigator-developed survey. Items inquire about participants' perceptions regarding the app's ease of use, aesthetics and graphics, and adequacy of the instruction (all rated on 1-5 scales, with higher ratings reflecting greater perceived appropriateness), and three items about the appropriateness of the duration of daily meditations, sleep meditations, and Sleep Stories (rated on a 1-4 scale, with higher ratings reflecting greater perceived appropriateness). Average scores will be reported for each item. | Participants' perceptions of appropriateness are measured immediately after the the conclusion of the 8-week intervention. |
| Demand, as assessed by the percentage of participants who use the mindful meditation app for the 70% of the prescribed weekly minutes (≥ 70 minutes/week) | The amount of time that participants use the app will be recorded by Calm (internally) and shared with Arizona State University. | Duration use app use is recorded continuously throughout the 8-week intervention. |
| Demand, as assessed by the the comparative frequency of participants use of meditation, sleep meditation, and Sleep Stories | The frequency of using individual app components will be recorded by Calm (internally) and shared with Arizona State University. |
| Measure | Description | Time Frame |
|---|---|---|
| Preliminary effects of the mindfulness meditation app on depression, as assessed by changes in participants' pre- and post-intervention scores on the Depression Anxiety Stress Scale-21 Items | The Depression Anxiety Stress Scale-21 Items is a set of three seven-item self-report scales measuring depression, anxiety, and stress/tension. Respondents use a four-point scale, ranging from 0 to 3, to rate the extent to which symptoms of depression, anxiety, and stress apply to their experiences during the past week (0=did not apply to me at all, 3=applied to me very much, or most of the time). For each scale, ratings for the relevant items are summed, and sums for each scale are multiplied by two to allow for comparison with scores from the original the 42-item version of the Depression Anxiety Stress Scale; thus total scores range from 0 to 42, with higher scores indicating greater depression, anxiety, and stress. |
