About this study

The purpose of this study is to find out how meditation influences certain systems in the body: nervous system, hormonal system, and respiratory system. Another purpose is to see how meditation may help improve post-traumatic stress disorder symptoms.

Read the detailed description

This study requires nine visits to the clinic: one screening visit, one baseline visit, six training sessions, and one endpoint visit. There will be approximately 100 people enrolled in this study who will be randomly allocated to one of four groups: a slow breathing group, a meditation group, a meditation plus slow breathing group and a sitting quietly group.

Participants will undergo a telephone screening, a screening visit, baseline visit, six intervention visits (once per week for six weeks), and one endpoint visit (one week after the final training visit). A telephone screening and screening visit will ensure participant eligibility. The screening visit included structured clinician interviews on PTSD symptoms and other mental health disorders, completion of questionnaires, and receipt of home saliva collection kit. At the baseline visit, electrodes will be attached to measure the electrical activity of head, chest, skin, and respiration and blood pressure during a computer task. Intervention visits include slow breathing, meditation, mediation and slow breathing, or sitting quietly depending on which group the participant is allocated to. Breathing rates and other electrical activity of the body will be measured also. Breathing rate will be measured with an elastic band that is placed around the chest. Electrical activity will be measured by the electrodes that will be placed on the scalp, chest and skin. The endpoint visit will be exactly the same as the baseline visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Slow BreathingBehavioural

    The slowed breathing group will be trained on a breathing device, RESPeRATE, designed to reduce respiratory rate.They will practice with RESPeRATE once a week (for 6 weeks) in the laboratory with the research staff.

  • MeditationBehavioural

    The Mindfulness Body Scan meditation will be used for the mindfulness meditation group.Participants will be trained once a week (for six weeks) in the laboratory by the research staff.

  • Meditation and slow breathingBehavioural

    A structured Mindfulness breathing will be guided by the research staff during the lab trainings. The participant will sit upright and attempt to focus attention on his or her own breath as it passes the opening of the nostrils or on the rising and falling of the abdomen or chest. Whenever attention wanders from the breath, the participant will simply notice the distracting thought and then let it go as attention is returned to the breath. Training will be given once every week for 6 weeks.

  • Sitting QuietlyBehavioural

    The SQ control group's "intervention" will include sitting quietly and listening to a neutral-content book on tape to serve as a time and attention control at each laboratory session. They will also be asked to sit quietly at home daily.

Questions about this trial

What is this clinical trial studying?

A study testing Slow Breathing, Meditation and Meditation and slow breathing in people with Post-Traumatic Stress Disorders, run by Oregon Health and Science University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 13 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Attentional Network Task: conflict effect score (time frame: Change from Baseline to Endpoint visit (one week after last training visit)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2015.
