Lay summary Background and study aims
It is well known that people who have experienced adversity in life are more prone to develop depression and anxiety. Through a research study it became evident that through prayer clients with this adversity experienced a release from the negative emotions and a related decrease in pondering of the hurtful events enabling them to move towards steady mental health more readily. This study aims to document the neural correlates of what is transpiring as the above occurs.

Who can participate?
Adults who are depressed but not on medication and are willing to engage in Christian prayer can participate in the study.

What does the study involve?
Participants are randomly allocated to one of two groups: the intervention group or the wait-list control group. People in the intervention group receive initial evaluation and prayer. Each prayer session lasts for about an hour and is conducted once a week for 6 weeks. Magnetic Resonance Imaging is done at the start and end of the study to record any changes happening in the brain. The wait-list control group will receive all the prayer sessions and evaluations as the interventions group but after 4 weeks.

What are the possible benefits and risks of participating?
This research does not involve major risks. Some clients may be disappointed in the prayer results while others may be encouraged.

Where is the study run from?
Baylor College of Medicine, Houston, Texas, USA.

When is the study starting and how long is it expected to run for?
The study starts in October 2013 and runs until April 2014.

Who is funding the study?
The Institute for Spirituality and Health, USA.

Study design Randomized wait-listed control study
Countries of recruitment United States of America
Disease/condition/study domain Emotional disorders
Participants - inclusion criteria 1. The subjects will be adults (male and female) between the ages of 18 and 65 who are depressed but not on medication
2. They will be willing to engage in Christian prayer and be without reservations or contraindications to fMRI scanning
Participants - exclusion criteria 1. All children, pregnant women, mentally impaired and those with physically incapacitating problems will be excluded
2. Individuals with other psychiatric disorders and those who have received professional psychotherapy or have been on antidepressants in the 3 months prior to study enrollment. Subjects with severe depression and/or suicidal ideation will be excluded and proper referral made.
3. Those who are unable to respond to the questions or would have difficulty maintaining a focus while responding to the questions during the scanning would also be excluded. Subjects will be allowed to engage in their usual private prayers, devotions and church-related activities. They will not be allowed to participate in any form of psychotherapy during the time period they are in prayer session or are wait-listed. This restraint is lifted for the time period between the completion of their prayers and the one-year follow-up.
4. Additionally, subjects who are unable to understand and follow the directions involved in the testing will be excluded

For the fMRI portion of this protocol, other exclusion criteria are:
1. Claustrophobia (this would make lying in the scanner very uncomfortable)
2. Pregnant
3. Contraindications to MRI: pacemaker, aneurysm clips, neurostimulators, cochlear implants, metal in eyes, steel worker, or other piercings and implants
Anticipated start date 07/10/2013

Patient information material Not available in web format, please use the contact details below to request a patient information sheet
Target number of participants 24
Interventions Group A receiving immediate evaluation and Christian prayer
Group B wait-listed prior to following the same protocol as Group A

Baseline rating scales and fMRI are performed immediately on entrance into the study. Subjects are then randomized into Group A or B. Group A goes into prayer intervention. Immediately at the conclusion of the prayer sessions both groups are re-evaluated even though Group B had no prayers. Group B is re-evaluated again prior to commencement of their prayers and at the conclusion of their prayers. Wait-list controls will receive their prayers within 4 weeks of the conclusion of prayers in the intervention group. Prayer sessions are 60 minutes in duration and conducted once a week for a duration of 6 weeks.
Primary outcome measure(s) Brain changes resulting from prayer as documented through fMRI
Secondary outcome measure(s) 1. Clients that meet the requirements of the study are measured for the severity of their depression utilizing the Hamilton Depression Rating Scale (HDRS) with 17 items. Potential subjects who are not on antidepressant or antianxiety medication and have a minimal score of 8 on the HDRS will qualify for the study. The Hamilton Anxiety Rating Scales (HARS) with 14 symptom-related questions will be used to test anxiety.
2. The Life Orienting Test (LOT) will be used to measure the effects of dispositional optimism on self-regulation in a variety of circumstances. It has shown construct validity with other studies demonstrating the effect of optimism health promotion in a variety of circumstances.
3. The Daily Spiritual Experience Scale (DSES) will use 16 questions to assess daily spiritual experiences in six domains
