Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
It is anticipated that the mBrain Process will be around 30 to 40 minutes. The intervention is done on an individual face to face basis by one therapist. There will be two therapists doing the intervention who are trained in mBrain work. It is a talk therapy. The time in each stage is about half so 15 to 20 minutes in stage 1 and stage 2. The two therapists are located at 6 Rangiwai Rd, Titirangi, a suburb in west Auckland.
Stage 1 – Autonomic Balance
Participants will be taught how to use a balanced breathing regime to regulate their autonomic nervous system. This will be guided by a script, but through observation of the participant may require some individualisation to ensure compliance.

Stage 2 mBrain Meditation
A scripted mBrain Meditation (which will be recorded for consistency) will be played for each participant, with sufficient space for internal processing and accessing of head, heart and gut intelligence.

The therapists who administer the therapies are trained in alternative therapies of which mBrain therapy would be considered.

Comparator / control treatment
A basic mindfulness meditation which still focuses on breathing, but does not intervene with breathing rhythm. This will take the approximately the same length of time as the intervention arm.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once enrolled a treatment code will be obtained from www.caseweaver.co.nz
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomization will be carried out using the Caseweaver.co.nz controlled trials package which enables concealed randomization to occur.
a. Patients are randomised to the control group or intervention arm by way of the standard built-in random number generator on the server. This produces a random number of zero (assignment to the control group) or one (assignment the treatment arm). Each time the application launches, the random number generator is initialized with a random value, which is obtained from the system clock.
b. Patients are identified by way of a study identifier.
c. When a patient is enrolled into the trial, they are randomly assigned to either the control arm or the intervention arm. This is recorded on the server, made visible to the investigator, and used with subsequent data entries.
d. When data are sent to the server, they are encrypted prior to saving in the database, and decrypted on demand when it is required for display or reporting. This means that all the trial data in the database are encrypted. Access to the data is restricted to the investigator or other users to which the investigator has explicitly delegated access privileges (such as a research assistant). User passwords are also stored encrypted in the database, plus additional measures are applied to ensure that it is impossible to deduce someone's password from the database.
e. For additional security, access is restricted by requiring that each user has a "client certificate" installed on their computer, in addition to having their username and password. This is referred to as "two factor authentication".

Intervention assignment
Parallel
Other design features
The participants will sign a certificate of validation at the end of the intervention (as there are some outcomes measured at the end of the first visit) to state that the interviewer did not do anything to influence their filling out of the questionnaires.

Efficacy
Statistical methods / analysis
The analysis will done by intention to treat analysis. For the categorical outcomes expressed using counts (percentages) and compared between treatment groups using the Chi squared test. Continuous variables will be expressed using mean (standard deviation) and compared between groups using an analysis of variance. The multivariate models for the dichotomous outcomes will be evaluated using logistic regression to calculate odds ratios (which will be converted to risk ratios using the formula of Zhang), with confidence intervals. The continuous outcomes will be analysed using multiple linear regression. All multivariate models controlled for age and gender (and the baseline level of STAI for the primary outcome of STAI). Missing data at 4 weeks will be imputed. A two-tailed p value< 0.05 was considered to be significant. Statistical analysis was performed using SAS V.9.3 (SAS Institute Inc., Cary, North Carolina, USA).

Summary
Brief summary
This trial plans to study an intervention called mBrain therapy to evaluate if it is more effective than a mindfulness control activity for people with significant anxiety. As a new field mBraining is showing some encouraging results but at present lacks a robust empirical base to show unequivocally that it works in practice. Stress and Anxiety is one area where mBraining is having encouraging results and it is for that reason that we believe it would be valuable to evaluate mBraining in this study to demonstrate the impact that can be experienced through teaching new behavioural patterns which lead to the balancing of the autonomic nervous system. The intervention is a basic physiological taught technique to reduce the sympathetic response caused by stress and anxiety. It is our belief that the impact from the foundational mBIT Processes would be more significant and longer lasting.
