NCT05802004

Brief Summary

In this study, the investigators will recruit young adults (ages 18-25 years) with elevated anxiety/depression symptoms and sleep disturbance. Participants will complete two overnights in a sleep lab. During one of the overnights, slow-wave activity will be enhanced by delivering sub-arousal auditory tones during slow-wave sleep using a headband device (Philips SmartSleep or Dreem 2). During the other overnight, tones will not be administered. Cognitive and emotional processes will be evaluated using behavioral task performance, self-report, and functional magnetic resonance imaging (fMRI). After the second overnight, participants will take the headband device home and wear it every night for approximately 2 weeks. For half of the participants, the headband will play tones every night and, for the other half, the headband will not play tones. Participants will then return for a final testing visit in which cognitive and emotional processes and anxiety/depression symptoms will be assessed using behavioral task performance and self-report.

Eligibility Criteria

Age18 Years - 25 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age 18-25. Equal numbers of men and women will be included.
  • Normal hearing.
  • Elevated anxiety or depression symptoms. This will be determined using the PROMIS anxiety and PROMIS depression scales. Participants with T-scores ≥ 60 (i.e., ≥ than 1 standard deviation above the mean) on either or both scales will be eligible for participation.
  • Elevated sleep disturbance. This will be determined using the PROMIS sleep disturbance scale. Participants with T-scores ≥ 55 on the PROMIS sleep disturbance scale will be eligible for participation.

You may not qualify if:

  • Presence of a severe chronic or psychiatric condition including psychosis, bipolar disorder, developmental disorders, or substance use disorder.
  • Current use of psychotropic medications or medications affecting sleep/wake function, such as antidepressants, antipsychotic medications, steroids, and stimulants. Rationale: These medications may affect sleep and cognitive-emotional function.
  • Substance abuse. Rationale: Substance abuse may affect sleep and cognitive-emotional function.
  • Consumption of \> 14 standard alcoholic drinks per week. Rationale: excessive alcohol consumption may interfere with sleep and cognitive-emotional function.
  • Consumption of \> 400mg of caffeine per day, which is roughly equivalent to 3-4 8oz cups of coffee per day.
  • Drug or alcohol use \< 48 hours before the in-lab overnight sessions. Rationale: Recent drug or alcohol use could affect sleep, cognitive-emotional processes, and poses a safety risk.
  • Severe insomnia or sleep apnea symptoms. Insomnia symptoms will be determined using the Insomnia Severity Index. Participants with severe insomnia (i.e., scores \> 21) will not be eligible. Sleep apnea symptoms will be determined using the STOP-Bang questionnaire. Participants with scores ≥ 3 will not be eligible. Rationale: Sleep disturbances which result in low sleep efficiency and frequent awakenings during the night may reduce the effectiveness of acoustic stimulation which targets the deepest stage of sleep (i.e., slow-wave sleep).
  • Extreme bedtimes (\< 10:00pm, \> 1:00am) or wake times (\< 6:00am, \> 10:00am). Rationale: Participants with extreme bed or wake times may have difficulty falling asleep, waking up, or obtaining a sufficient amount of sleep during the in-lab overnight sessions.
  • Short (\<5hrs) or long (\>9hrs) average sleep duration. Rationale: short or long sleepers may have different sleep profiles which could impact the effectiveness of the acoustic stimulation intervention.
  • Uncorrected vision problems.
  • Claustrophobia. Rationale: MRI safety criteria.
  • Metal in body. Rationale: MRI safety criteria.
  • Body Mass Index (BMI) \> 40. Rationale: MRI safety criteria.
  • Pregnancy. Rationale: MRI safety criteria.
  • Left handedness. Rationale: Left-handed people may have different lateralization of neural functioning which could affect the fMRI results.
  • +4 more criteria

Data Sharing

IPD Sharing
Will share

De-identified IPD associated with publications will be made available to researchers upon reasonable request. IPD will also be stored in a central data repository at the University of Pittsburgh, which can be accessed by researchers at the institution who have appropriate qualifications and access information. Examples of IPD that can be shared with other researchers include descriptive data such as means and de-identified performance scores on cognitive and emotional tasks, self-reports of mood or anxiety/depression symptoms, summarized sleep EEG data, and summarized fMRI data.

Shared Documents
STUDY PROTOCOL
Time Frame
Data will become available once data collection is finalized. IPD associated with manuscripts will become available once the manuscript is published.
Access Criteria
To access the data, the requester must have completed and up-to-date research and ethics training and data use or material transfer agreements must be in place.
