Mindfulness Meditation for Insomnia
What this study is about
The investigators will conduct a 3-treatment group$1, pilot RCT where participants (N=30) will be randomly assigned in a 1:1:1 design to 4 weeks of instructed bedtime MM practice at night (n=10) vs. uninstructed MM (n=10) vs. sleep hygiene education only (n=10). Aim 1 is to understand the feasibility and acceptability of the intervention and study procedures.
View original scientific description
The investigators will conduct a 3-arm, pilot RCT where participants (N=30) will be randomized in a 1:1:1 design to 4 weeks of instructed bedtime MM practice at night (n=10) vs. uninstructed MM (n=10) vs. sleep hygiene education only (n=10). Aim 1 is to understand the feasibility and acceptability of the intervention and study procedures. Aim 2 is to explore patterns of within-group changes in sleep outcomes (i.e., insomnia severity and sleep quality). Patient-reported outcomes will be collected using a HIPAA-compliant electronic data management system (REDCap). Following informed consent, participants will receive links to REDCap surveys via email at Weeks 0, 4, 8, and 16. The investigators will also conduct a post-intervention interview at the end of Week 4 and an exit interview at Week 16. All participants will also receive a research kit with wearable devices and meet with our staff after they receive the kit for instructions. Data collected in the pilot RCT will help us to preliminarily identify tools for subjective measures and physiological signals to inform a future trial.
Interventions
BEHAVIORAL
Instructed bedtime app-guided mindfulness meditation
All participants will access the a smartphone app, and the mindfulness meditation practice may involve techniques such as breathing exercise, imagery, body scan, and relaxation. The investigators will provide instructions for participants who are assigned to practice at bedtime.
BEHAVIORAL
Uninstructed app-guided mindfulness meditation
The guided mindfulness meditation practice will also be based on the same app. The investigators will not provide instructions for participants, and they have complete freedom to use the app as real-world users.
BEHAVIORAL
Sleep hygiene education
Sleep hygiene education will be based on recognized, general, non-personalized sleep hygiene advice, for example, recommendations about bedtime routines and use of alcohol and caffeine, tips on creating a sleep-conducive bedroom environment.
Primary outcome measures
Screened-to-eligible ratio
Time frame: Week 0
The proportion of screened participants who were determined to be eligible for the study; calculated as the number of eligible participants divided by the total number of individuals screened.
Retention rate
Time frame: Weeks 4, 8, and 16
Retention rate is defined as the percentage of participants who complete the entire follow-up period. Reasons for participant dropout will also be documented.
Adherence to intervention protocol
Time frame: Week 4
In the intervention groups, a mindfulness meditation session ≥ 10 minutes will be considered as a completed session. Numbers of sessions completed during the four weeks will be recorded. Adherence to intervention protocol will be defined as those randomized to the intervention groups complete ≥ 70% of home practice.
Compliance with outcome assessment
Time frame: Weeks 0, 4, 8, 16
Compliance with outcome assessment will be determined by the percentage of participants who complete ≥ 70% of questionnaires at each time point.
Acceptability
Time frame: Week 4
At intervention end (week 4), a brief questionnaire will ask participants to rate (1=not at all to 5=very much) the enjoyableness, convenience, helpfulness, and overall satisfaction with the app-based mindfulness practice. Acceptability is assessed by self-report survey ratings, and a threshold of 80% ratings of 4 or higher will indicate acceptability.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age 18 years and older;
- Chronic insomnia (≥ 3 nights/week, for ≥ 3 months), defined by DSM-V or ICSD-3;

- Insomnia Severity Index score ≥ 15;
- Speak and understand English;
- Have a smart device (phone or tablet) for mobile app installation
Exclusion criteria
- Current diagnosis of sleep disorders other than insomnia (e.g., narcolepsy, restless leg syndrome, REM sleep behavior disorder, etc.);
- Shift worker or routine night shifts;
- Women with pregnancy or breastfeeding;
- Regular (defined as twice a week or more) practice of mind-body interventions;
- Patients with pace-maker or routinely using cardiovascular medications that have effects on heart rates (i.e., beta-blockers);
- Neurological disorders (e.g. epilepsy, dementia, stroke, Parkinson's disease, neuroinfections, brain tumors, etc.) or current diagnosis of comorbid psychotic, substance use, and trauma-related disorders;
- Currently under medications with sleep changing effects (e.g., anxiolytics/benzodiazepines, selective serotonin reuptake inhibitors, hypnotics, etc.);

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
