Study type
Description of intervention(s) / exposure
An eight week training in Mindfulness Based Stress Reduction consisting of 2.5 hours of instruction per week and 45 minutes per day of home practice. The course will utilize the materials from (permission has been sought and received from the site owner), which include video and written materials. Mindfulness practices include mindful eating, body scans, focused breathing and gentle yoga poses. These are conducted during the sessions and in home practice tasks. The palousemindfulness course is designed to be self-directed; however in this case the participants will meet as a group with a university student (doctoral student in clinical psychology) acting as facilitator. Maximum group numbers will be 10 per group. The group will be conducted in a meeting room at the rooms of the gastroenterologist (Dr Lauren Beswick) associated with the study. Each week participants will be given homework sheets to record their home practice; these will be collected and the times recorded as part of the data collection. The intervention is in addition to the standard care each patient will receive as part of their ongoing treatment with the gastroenterologist.

Treatment: Other
Comparator / control treatment
Standard care.They will continue to get care and treatment as usual, according to their individual needs and as determined by their gastroenterologist. They will be offered the opportunity to participate in the same Mindfulness Based Stress Reduction Course that the intervention group received. The course will be offered to the control group in 2020, which will be following the 6 month follow up period of the data collection phase.
Control group

Primary outcome [1] 308360 0
depression symptoms as determined by measurements on the Depression Anxiety and Stress Scale (Lovibond & Lovibond 1995)

Immediate post-intervention and six=month follow up
Secondary outcome [1] 354724 0
Homeostatically Protected Mood variability. This will be tested through a series of statistical analyses to participants answers to questions, how happy/content/alert they feel during a tw0-week ecological momentary assessment period. The statistical analyses will include within-person standard deviation, mean successive square differences and multi-level-modelling.

Secondary outcome [2] 354725 0
Inflammation levels through levels of C-reactive protein. These will be accessed through blood test results. Blood samples will be collected by the patient’s gastroenterologist as part of usual care.

4) Competence to consent
5) Access to the internet by a smart phone and the willingness to download the Instant Survey app.
6) A willingness to commit to 2.5 hours of MBSR at the identified times for a period of 8 consecutive or near-consecutive weeks, and engage with the homework sheets in the intervening period.
7) Scores of depression at mild or moderate levels of the DASS scale
Minimum age
18 Years
Maximum age
No limit

Key exclusion criteria
1) Alcohol/substance dependence, as identified by the gastroenterology team
2) Severe mental illness (e.g. psychosis, schizophrenia), as identified by the gastroenterology team
3) Severe anxiety or depressive symptoms as indicated by a scores >21 on the depression scale or > 15 on the anxiety scale of the DASS measure

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients meeting the inclusion criteria and providing consent to participate in the trial will be randomly assigned to either group A (mindfulness) or group B (waitlist/usual care). Patients in both groups will continue to receive their current treatment for their Crohn's disease. A researcher who will have no patient contact will be responsible for sequence generation and for preparing sealed envelopes in the allocation order. Those envelopes will be provided sequentially to patients meeting the selection criteria following the screening process.

Patients in Group A will receive the intervention in 2018 and will be required to provide subjective mood data via an app for two weeks prior to and two weeks following the 8-week intervention. Patients in Group B will receive an opportunity to attend a mindfulness course in 2020 and will be required to provide the same subjective mood data via an app for a period in 2019 that will parallel the data collection for Group A. Patients who have been allocated to Group A will be provided with two choices for mindfulness group meeting times and days. If neither time is convenient for them, they will be removed from the trial.

Intervention assignment
Other design features
The intervention involves participation in an 8-week mindfulness course, it is therefore not possible for it to be a blinded trial.

The data will be analyzed by the student researcher responsible for delivering the intervention.

Brief summary
The study aims to contribute to understanding of the relationship between stress and inflammation. It is thought that, during period of high psychological stress and inflammation, an individual's inner homeostatic system that controls mood and emotional regulation is challenged such that homeostasis is no longer functional. The study will explore whether a mindfulness intervention can aid in the restoration of homeostasis, and, if so, whether this restoration is also associated with a reduction in inflammation, perceived stress levels and symptoms of depression.
